PREFACE
History and examination are essential parts of clinical practice and key elements in
medical training, requiring constant supervision and evaluation. The assessment of
these skills is therefore a mandatory requirement of every medical school. The form
of this assessment varies: continuous assessment is common, and desirable, with
constructive feedback, to ensure that students are developing appropriate skills.
The primary aim of this text is to reduce the chances of failure in the clinical part of
surgical finals. This is by encompassing the core knowledge and skills needed to
pass finals, and providing a reliable and safe approach to patients and their
surgical problems; it also addresses the requirements of the various forms of
assessment that are in current use. Student as well as staff involvement in the
initiation and development of the first and subsequent editions has retained a close
link to teaching and assessment methods, and most importantly to clinical practice.
The text takes the candidate through the clinical history and examination of
frequently encountered surgical conditions and common written or verbal questions
that are added to manned or unmanned examination stations. The emphasis is
surgical and topics more pertinent to medical specialities, such as cardiac,
respiratory, neurology, dermatology and psychiatry, are not included. For these and
other aspects of finals, consult the companion Medical, OSCE and EMQ volumes.
We hope that the continued popularity of the text reflects its close link to the
examination systems across the UK and reader’s success in his or her surgical
finals.

INTRODUCTION
By the end of your undergraduate training you will have probably accumulated
enough knowledge and clinical experience to pass finals; however, clear
organisation of factual material and refining of your clinical skills increases your
confidence, reduces examination stress and ensures optimal performance. This
book addresses the clinical aspects of the examination in a concise, ordered and
meaningful way, presenting essential information in a form that is linked to the
various examination systems that are in current use across the UK.

SYLLABUS CHECKLIST
As an aid to revision, use this syllabus as your own personal checklist. Page
numbers are given in brackets after each case. You should aim to achieve at least
two ticks per case before the date of the examination. If you have not actually seen
a condition, look it up in an illustrated textbook.

FORMAT
The examiners
Examiners of a long case traditionally work in pairs. There is normally one
‘internal’ examiner (from your own teaching hospital) and one ‘external’ (invited
from outside). The difficulty in finding enough clinical material to assess large
numbers of candidates has led to the merging of medical and surgical cases and an
increase in assessments of structures. However, the text has been structured to be
applicable to all forms of assessment.
You will usually be told who your examiners are. It is worth knowing their special
interests, even though their questions will not be confined to these areas. Talk to
medical students who have been taught by your examiners to find out any particular
preferences in examination technique (eg always kneeling down to examine the
abdomen).
The patients
The range of conditions that you will see in the examination is not necessarily
representative of the conditions seen in general hospital care. First, you will never
be given a very ill patient with, for example, an acute abdomen or an acutely
ischaemic limb. Second, there are some rare conditions that crop up
disproportionately in examinations: such patients usually have long-standing
problems with good physical signs. Examples are AV malformations or carotid
body tumours.
Patients are drawn from four sources: inpatients, patients coming up from clinics,
‘professional’ patients and simulated patients.
21
1. Inpatients
Most inpatients transferred to the examination will be awaiting operations such as
hernia repairs or removal of breast lumps. Postoperative patients are also available
for the clinicals: after all, you will be expected to manage such patients in your F1
and F2 years. A minority of patients will be those recovering from acute conditions,
with good histories and/or physical signs that have not yet resolved.
3. ‘Professional’ patients
These are patients with long-standing signs who are listed on a computer database
and who have been called up numerous times in the past. Such patients are usually
excellent historians and may even point out their physical signs.
4. Simulated patients
Simulated patients are healthy individuals who are trained to simulate a patient’s
illness in a standard manner. They are usually actors. Some training is usually
required to ensure that they are able to bring out the main points in the history on
request and within the time allowed. Simulated patients can become skilled
historians and very persuasive patients, such as when replicating a psychiatric
disturbance. They are often asked to give their own marks on the student encounter.
PREPARATION
Early preparation
22
Don’t fall into bad habits
Ask a doctor to watch you examine and listen to your presentations as early and as
often as possible. Without this, it is very easy to acquire bad habits that are difficult
to break.
Act as a chaperone
Senior medical students in their clinical years are often used as ‘chaperones’ in
clinical examinations. Their role is to escort the candidates from room to room,
ring the bells and ensure that the examination runs smoothly. If you are given this
opportunity, take it. You will get an idea of the examination format and there will
often be time to examine the patients yourselves afterwards. There can be no better
preparation: some of the same patients may even come up the following year.
Bleep the FY1 and FY2 and ask for lists of patients to see as long and short cases.
Ask when patients are to be admitted. Also find out when day surgery lists take
place: here you will find many swellings, ulcers, varicose veins and hernias to
examine.
23
Revise efficiently
This book gives plenty of lists of clinical features and provides tables of
differential diagnoses. Modify these to make your own lists: you will remember
best what you compile yourself. Laptops or card systems may be a useful revision
aid at this stage.
Try not to work late into the night, relax before you go to bed, avoid excess coffee
and keep up physical exercise. You will retain much more if you are alert during the
revision period than if you are exhausted. Remember that hypnotics and anxiolytics
can dull your mind on the day of the examination: take them only under medical
supervision.
24
Long cases in finals may be combined medical and surgical assessment with one or
two examiners. You may or may not be observed during the history and
examination. Often you are taken back to a patient to demonstrate specific signs.
The traditional long case format has inherent problems of objectivity and
reliability. In response to such problems, standardised patients and markings
systems have been introduced. These include the introduction of the ‘objective
structured long examination record’ (OSLER). The OSLER might include more than
one case (a real patient, a simulated patient or a video, see here), each allocated
20–30 minutes, usually with a single examiner. This allows the examiner to test
specific aspects of knowledge, skills or management decisions. Shorter periods
may be allotted to specific parts of the history taking or focal examination.
25
patient is comfortable at all times. Do not ask the diagnosis immediately. On the
other hand, if you gain the patient’s sympathy, he or she may point you in the right
direction and may even show you physical signs.
The history
Go through your usual scheme, which should be familiar by now. You will probably
be given paper and a writing board. Start with name, age, occupation and marital
status. This is followed by seven headings.
1. Presenting complaint
Ask about the main problem(s). List these together with a time scale, eg
• Nausea: 4 days
5. Family history
Again, include questions about anaesthetic reactions.
26
6. Social history
A good social history will make you stand out from other candidates. Don’t just ask
about alcohol and smoking; check environmental hazards (eg asbestos exposure). It
is important that you know how well the patient will manage at home during the
postoperative period. Therefore ask about family, neighbours, carers, GP home
visits, district nurses, home help, meals on wheels and financial problems.
Your social history should be relevant to the patient’s problem, so if you have a
patient with a stoma, enquire into the details of stoma care, and whether they can
change the bag themself. If you have a patient with an orthopaedic problem or
amputation, ask about physiotherapy, occupational therapy, aids and appliances.
7. Systemic enquiry
As in subsequent sections.
The examination
Your hands should be washed clean and warm before commencing any examination.
(For more than one station there will usually be an alcohol wash at the bedside; if
not, ask an attendant where you can wash your hands.) Your examination may be
observed by an examiner. This does not mean that you should change your clinical
approach: the order for general and regional examination is just the same, as
outlined in the text, and the one you have practised with supervisors and your
chosen colleague (here).
27
drummed into you by your teachers, and look, feel, move and measure for joints –
this is not the time to forget them! When palpating, always watch your patient’s face
for distress, and apologise for causing any discomfort. When auscultating, warm the
bell or diaphragm and tap the end to make sure that you are plugged into the right
bit before you start.
An examiner may ask what you are doing at each stage; take this into account when
you are preparing with a colleague and do likewise. When you have finished your
examination make sure that the patient is covered and comfortable.
Thinking time
If you are not being observed you will usually have a few minutes between
examining the patient and presenting your findings. During this time, reorganise any
misplaced information and summarise the case in writing. You might also predict
your examiners’ questions so that you are one step ahead. The sections on ‘typical
cases’ in this book will help you to do this.
If your patient was a poor historian, start by commenting on this fact: this is an
important sign in itself and allowances will be made. However, it is no excuse for
a poor presentation.
If the patient has more than one complaint this should be brought out by listing the
presenting complaints. Then explain, ‘I will describe each of these in turn.’
You should not give long lists of negative findings: if the main problem is
abdominal and you have found no other abnormality, it is quite permissible to state
that ‘other systems are normal’.
28
The examiners may interrupt you in the middle of your presentation. They may be
happy with the way that you have started and want to go on to the next point, they
may wish to discuss a problem in more depth, or they may simply be bored after
listening to several well-delivered histories in a row.
You may be taken back to the patient to demonstrate an abnormal finding. This does
not necessarily mean that there is any doubt about your findings: you may have
elicited a sign previously missed! At the end of your presentation give the diagnosis
(if you are sure of it), and/or list the common differentials or causes of the patient’s
problem.
29
Objective structured clinical examination (OSCE) assesses a broad range of
knowledge and skills in a quantifiable, valid and reliable form. The OSCE aims to
assess your factual recall, your interpretative skills, your decision making, your
behavioural attitude in professional practice and your ability to perform particular
practical tasks. It ensures that each of you is presented with the same material and
therefore provides a uniform evaluation and marking system.
The OSCE often includes short cases. These are probably the most difficult part of
the clinical examination because you will be required to examine a patient under
the eagle eye of one or two examiners. The examiners will watch for three things.
30
• Do not take the examination schemes provided in this book as gospel. Modify
them according to your own teaching and individual preference.
• Don’t be such an automaton that you fail to listen to the instruction: if the
examiner tells you to ‘palpate the abdomen’, do not start with the hands.
• Passing the short cases is rather like passing a driving test: you must actually
show your examiners that you are following the correct routine, eg by standing at
the end of the bed to observe the patient.
• Although you are not supposed to take a history during the short case, you are
allowed certain questions, eg before examining a lump you cannot see, ask the
patient to point out its exact position.
There are certain things that you are not expected to include in the examination
situation, such as a rectal examination. However, you must indicate to the
examiners that you would normally examine these areas. Furthermore, you should
express a desire to examine other systems to seek underlying causes of local
conditions, eg tell the examiners that you would like to examine the abdomen for
secondary causes of hernias or varicose veins.
It is usually up to you whether you talk as you examine or you present your findings
at the end. Practise both ways: you may be requested specifically to ‘explain what
you are doing’ or you may be interrupted at any stage of the examination to ‘present
your findings so far’.
Seek clues from the beginning: observe all the artefacts around the patient such as
drips and catheters. Plastic gloves next to a patient with a submandibular swelling
indicate that you are expected to palpate the gland bimanually. A glass of water next
to a patient with a neck swelling suggests a goitre.
Never forget to look at the patient as a whole, even when you are asked to examine
31
one small part: rheumatoid nodules on the elbow suggest the diagnosis before you
have even looked at the hands.
OSCEs assess your interpretive skills, preparation and progress, as well as factual
recall; they include task-oriented items and they can examine your powers of
decision making, problem solving and behavioural attitudes in simulated
professional practice. The overall effect is to provide a valid assessment of
clinical practice.
32
Medicine involves a great deal of communication, with both patients and
colleagues from all disciplines. Thus presenting clinical findings, answering
related questions, and discussing differential diagnoses and subsequent management
are a routine part of clinical practice. Do not therefore be surprised to be asked
further questions about your clinical findings.
If you are unfortunate enough to be in this group, take courage from the fact that
there are usually two examiners looking for reasons to pass you. The examination
usually follows a standard approach, and paying attention to the viva techniques
outlined below and the content of the subsequent pages will make it less of an
ordeal. They are likely to cover a number of topics to ensure that your knowledge
across the syllabus is at a safe and competent level for you to progress.
You should also be aware that any part of the clinical examination can turn into a
‘mini viva’. The frequently asked questions throughout the text cover the topics,
and answers, that make up the standard surgical viva.
The other type of viva that you may be fortunate enough to be part of is the
distinction viva – equally terrifying! Here the rules are different; the examiners are
assessing a depth of surgical knowledge beyond the contents of this book. They may
start off with the same standard questions, but will then ask the details of probably
two topics, pushing you to your limit. You may think that you shouldn’t be there and
be tempted to withdraw – but don’t – it is as an enlightening experience, you can’t
be marked down and your luck may hold! Scan through topics that have been
33
covered in surgical journals over the last year online and when you find ones that
interest you read them in detail – you may have to visit the library to find the full
text. The examiners will have read the same material and will enjoy the discussion
– good luck.
VIVA TECHNIQUE
Note the following points:
• Although you will be nervous, try not to show it: aim to give an impression of
calm confidence.
• Try to hold the attention of your examiners: speak audibly and clearly. Keep
eye contact with at least one of them.
• When asked a question, consider for a moment before rushing into an answer.
However, do not hesitate too long because this makes you appear uncertain.
• If you do not understand a question, admit it, put it behind you and be ready
for the next question.
• Once you get onto a topic that you know, keep talking as long as you have
positive factual knowledge to offer. Drop your voice slightly on the final
sentence so that the examiners know that you have completed your statement;
try not to peter out.
• Don’t dig yourself a hole mentioning a very rare condition or something about
which you know little or nothing. The examiner could very well ask you to
elaborate (‘Oh yes, tell me more about that’).
• Don’t worry if some humour arises and you are excluded: examiners are
pleased to have some light relief during a heavy day’s examining. However,
do not go out of your way to be funny because this can fall very flat.
34
• At the end, do not rush off as soon as the bell rings: the examiner decides the
finishing point, not you. When the end is signalled, smile and thank the
examiners, regardless of your feelings. Leave quietly at a normal pace. Try
not to trip, knock over the chair or slam the door!
ORGANISATION OF INFORMATION
Always show the examiners that you can classify information. The following ‘time-
honoured’ mnemonics will help you organise your information, but if you make up
your own they will be more memorable.
A disease
You may be asked to talk about a particular disease. Use a pathology sieve to
structure your answer. One aide-mémoire is ‘Dressed In a Surgeon’s Gown A
Physician Might Make Progress’: Definition, Incidence, Sex, Geography,
Aetiology, Pathogenesis, Macroscopic pathology, Microscopic pathology,
Prognosis. This is modified to form a clinical sieve ‘… a physician Should
Succeed In Treatment’: Symptoms, Signs, Investigations, Treatment.
Aetiology
Examiners often ask the causes of a condition. Remember to mention common
causes before rarer ones. If you have not memorised a list for that condition, again
refer to a sieve. You may find the following mnemonic useful: CIMETIDINE –
Congenital, Infective, Inflammatory, Metabolic, Endocrine, Traumatic, Iatrogenic,
Degenerative, Idiopathic, Neoplastic, Everything else!
Management
The question ‘How would you manage a patient with this condition?’ comes up
again and again. The term ‘management’ is sometimes used loosely to be
synonymous with treatment. However, management refers to history, examination,
35
special investigations and treatment. You should always begin by saying ‘I would
take a thorough history and perform a full examination.’ Go on to describe the
special investigations that you would request and only then describe the treatment.
If asked about the management of trauma or shock, never forget to say: ‘This is an
emergency. I would first check the airway, the breathing and the circulation
(ABC).’
Special investigations
When asked about special investigations, start with simple investigations such as
urinalysis and blood tests: haematological (FBC, clotting studies, group and save),
biochemical (U&Es, LFTs, TFTs, amylase) and urinalysis. Then go on to describe
relevant imaging investigations (chest radiograph, ultrasonography and Doppler
sonography, angiography, barium studies, CT and MRI), endoscopy and biopsies
(cytology and histology). Remember that all older patients being considered for
surgery should have a chest radiograph and ECG (think: 1 fluids, 2 tissues and 3
imaging).
Treatment
If asked about the treatment of any disease, always divide your answer into
conservative, medical and surgical. Under conservative treatment, consider the
contributions from all other healthcare providers such as nurses, physiotherapists,
occupational therapists and social services. Under medical treatment, consider
drugs, chemotherapy and radiotherapy.
Results of investigations
Familiarise yourself with plain radiographs, CT and MRI scans of the skull, chest
and abdomen, and barium studies, IVUs and angiograms. Examiners like to know if
you have actually seen these investigations and may ask you to describe the
procedures. You should also know normal haematological and biochemical values.
36
Pathology specimens
If handed a pathology pot, look all around the specimen: a discouraging amorphous
mass on one view may be easily recognised by the presence of a nipple or an
appendix on the other side. Note the organ, describe the abnormalities and make a
diagnosis. You may then be asked about the condition and how the patient might
have presented.
Other objects
You are expected to recognise a variety of instruments and tubing. These include an
endotracheal tube, a laryngoscope, a Guedel airway, a laryngeal mask, a chest
drain, a tracheostomy tube, a Sengstaken–Blakemore tube, a T-tube, a proctoscope,
sigmoidoscope and an endoscope. You may be asked to describe a practical
procedure such as how to catheterise or how to put down an endotracheal tube.
Emergencies
You must know about the management of the common surgical emergencies such as
the acute abdomen and acute upper and lower GI bleeding. These are ‘pass/fail’
questions.
37
The examination week is very intensive. Each day covers OSLERs/long cases and
OSCEs/short cases, and may include a viva. It therefore deserves forethought and
preparation, particularly on what you intend to take with you, what you will wear
and how you will make your way to the examination.
• Stethoscope
• Short ruler
• Tape measure
Neurological examination requires additional items that you can bring yourself,
although they will usually be provided:
• Cotton wool
38
• Sterile, sheathed disposable needles (wooden sticks, if against med. school
policy)
• Tuning fork
• Tendon hammer
• Ophthalmoscope.
Dress conventionally
Avoid appearing at all unconventional. Men should wear a plain dark suit, tie and
white shirt. Women should wear a smart dress or suit. Hair should be tidy: men
should have a recent haircut and women with long hair should tie it back. Make
sure that your nails are clean and your shoes polished.
Arrive on time
It is essential that you arrive on time and in a composed state. You can be sure that
there will be examiners and patients waiting for you, regardless of traffic delays or
train strikes. Excuses wear thin on such occasions. If you are not familiar with the
venue, a preliminary visit may be worthwhile in order to time your journey.
Aim to be at the examination at least 30 minutes before the listed starting time. This
will ensure that you are able to find the toilets, check your dress and equipment,
and fill in any necessary forms. It is a good idea, while waiting outside the
examination room, to write down the various headings of your history and
examination on the blank paper provided. Not only does this ensure that you do not
forget a heading in the heat of the moment, but it limits the space (and hence time)
that you spend on any one area.
39
Section 2
History, examination, typical cases
40
In surgical finals a long case is usually directed at a single system, and OSCE and
short cases at specific clinical signs, as considered in subsequent chapters.
Nevertheless be sure that you can undertake a structured general examination that
can be integrated with the examination of every system. Pain can be a feature of all
systems: be sure that you have a reliable system for questioning – the following can
serve as a template, but if you work out your own it will be more memorable.
The History
• Where is the pain? (Ask the patient to point to the area where the pain is felt
maximally)
• Have you ever had a pain like this before?
• When did you first notice the pain this time?
• Did the pain begin suddenly or gradually?
• Has the pain become worse since it started?
• Can you describe the pain? (?colicky, ?burning, ?aching)
• How severe is the pain? Does it keep you awake at night?
• Does the pain go anywhere else?
• Is there anything that makes the pain better?
• Is there anything that makes the pain worse?
• What do you think caused the pain?
A mnemonic may help you remember the important features: Site, Radiation,
Severity, Nature, Onset, Periodicity, Duration, Relieved by, Accentuated by,
Timing (eg State Registered Staff Nurse; Out-Patients Department; RAT).
Other common surgical features are lumps, swellings and ulcers (discharge,
bleeding), as considered in Chapter 7. In a long case, always quickly survey the
past, drug, social, family and systemic histories, as outlined on page 8; if you are
short of time, this can be done during the examination, but, as in your future clinical
practice, never omit this because unexpected things turn up during this enquiry and
41
the examiner may want to talk about them. Is there a urine sample by the bed that
you are expected to test?
THE EXAMINATION
As in all examinations, gain the patient’s verbal consent to proceed (see here). The
general approach assesses the wellbeing of the patient, both the mental and physical
conditions; you will already have gained a lot of information during your history
taking. The general assessment includes your general impression, and the
examination of the hands and the head and neck; this is integrated with the
subsequent examination of each system.

FAQS AND POPULAR VIVA QUESTIONS
1. What are the causes of anaemia?
9. What is CPR?
44
ANSWERS
1. Anaemia is a decrease in circulating haemoglobin. It can be classified according
to the size of the red blood cells (mean corpuscular volume / MCV describes the
average volume of a red blood cell):
a. Hypochromic microcytic (small size)
b. Normochromic normocytic (normal size)
c. Macrocytic/megaloblastic (large size).
Megaloblastic anaemia:
Megaloblasts are formed in the marrow due to defective DNA synthesis; the
deficiency is usually of vitamin B12 or folic acid. Levels are affected by poor
intake, loss of intrinsic factor in the stomach (gastrectomy, gastric atrophy
[pernicious anaemia and other autoimmune conditions] alcoholic liver disease
and occasionally small-gut and pancreatic disorders.
In surgical patients low haemoglobin (Hb) must alert the surgeon to a source of
blood loss. This can be:
45
a. Occult (hidden!), such as slowly bleeding gastric cancer that renders the
patient anaemic over a long period of time. The patient may present with
fatigue and shortness of breath
A low Hb with a low MCV and depleted iron levels should prompt further
investigation including faecal guaiac testing (looking for occult bleeding in the
GI tract) and urine dipstick (blood loss from the renal tract). A full menstrual
history needs to be taken in women, as well as an assessment of dietary habits.
Failing this, a CT scan of the chest, abdomen and pelvis may be the last resort.
Look for conjunctival pallor; in iron deficiency the nails are brittle and spooned
(koilonychia), there may be angular stomatitis, atrophy of tongue papillae and
46
glossitis. Pernicious anaemia may be associated with neurological signs and
hepatosplenomegaly, and all anaemias can show the symptoms and signs of an
underlying disease. In Plummer–Vinson syndrome, iron deficiency is associated
with dysphagia, leading to weight loss.
b. Hepatic: obstruction to the normal flow of bilirubin within the liver: this can
occur in most forms of acute and chronic liver disease, culminating in end-
stage liver failure, which can only be treated by transplantation. Hence,
hepatitis and end-stage liver failure in the form of cirrhosis can be mentioned
in the exams as a cause of ‘hepatic’ jaundice. Common causes are viral
(hepatitis B/C), alcoholic or autoimmune hepatitis
In the jaundiced patient, measure liver function tests. A high bilirubin confirms
the presence of jaundice. NB also check clotting.
Remember that high ALT levels confirm liver injury, while high ALP levels
indicate injury to the biliary tree downstream from the liver.
Hence high bilirubin with ALT > ALP suggests a hepatic cause for the jaundice.
A high bilirubin level with ALP > ALT suggests an obstructive cause (post-
hepatic) for the jaundice.
Also remember that in pre-hepatic jaundice the bilirubin is unconjugated (as the
47
liver’s metabolic capacity to conjugate is saturated), while in post-hepatic
jaundice the bilirubin is conjugated.
4. The symptoms of acute liver disease may be mild, but in viral infections can
progress rapidly to malaise, anorexia, fever and unconsciousness. The symptoms
of chronic disease depend on the cause; in addition to jaundice there may be
pruritus / itching (due to release of conjugated bilirubin, ie not in haemolytic
forms) gynaecomastia and testicular atrophy, and as liver failure progresses,
abdominal distension from ascites, confusion, drowsiness and bleeding from
oesophageal varices; obstructive disease can manifest as pale stools as well as
dark urine. Biliary symptoms include indigestion, colic and fever; pancreatic
pain occurs in the upper abdomen and radiates through to the back.
On examination:
a. Early jaundice is first observed in the frenulum of the tongue and best
observed in the sclera of the eyes, progressing to widespread cutaneous
staining
b. Look for xanthomas around the eyes; in the hands look for palmar erythema,
spider naevi, clubbing and Dupuytren’s contracture (most often in alcoholic
cirrhosis); in later stages liver flap (of the wrist), altered consciousness and
generalised purpura
c. in the abdomen the patient develops collateral veins around the umbilicus
(caput medusa), hepatosplenomegaly (the liver may shrink in late stages of
cirrhosis; splenic enlargement usually indicates portal hypertension); palpable
gallbladder (Courvoisier said it was unlikely to be a stone!); ascites (make
sure you percuss for it); abdominal masses (look for associated disease, such
as colonic cancer and lymphomas).
Remember that the symptoms and signs in liver failure are caused by portal
hypertension or impaired synthetic function of the liver.
Portal hypertension (as blood flow through the liver is impaired due to
structural changes brought about by cirrhosis). This causes splenomegaly (as
drainage of splenic blood is obstructed) and collateral blood routes form at
the site of portosystemic anastomoses. These give rise to oesophageal and
haemorrhoidal varices, as well as a caput medusa
48
gynaecomastia, testicular atrophy
Losses are usually due to vomiting and diarrhoea (cholera causing extreme loss
but other infections can also be rapidly lethal); fistulae; burns; major trauma and
blood loss. Fluid may be sequestrated, as in paralytic ileus. Excess sweating and
hyperthermia usually occur in hot countries but can result from prolonged
exercise without adequate fluids (eg marathon, triathlon). People in protective
clothing (eg chemical protection) are more liable to dehydration and
hyperthermia in hot climates. Polyuria is a complication of diabetes insipidus,
diabetes mellitus, hypercalcaemia, some uraemic states, diuretics and
postoperatively – all requiring measured fluid and electrolyte balance and
avoidance of over-zealous uncontrolled replacement.
6. Early symptoms of dehydration are thirst and a reduced and concentrated urine
output. There may be nausea, vomiting, cramps, weakness, paraesthesia and
orthostatic hypotension ( a drop in blood pressure when standing). Cerebral
symptoms of a reduced circulating volume include headache, ‘hangover’
sensation, dizziness and fainting, progressing to delirium, seizures and
unconsciousness.
Signs include tachycardia, hypotension and pyrexia. The skin is dry and lax
(check over the back of the hands); dry tongue; dry or cracked lips; sunken eyes
with absent lacrimation. Altered mental state is present as symptoms progress.
7. Cardiac failure occurs when the cardiac output is insufficient to meet the
49
metabolic and perfusion needs of the body. It may be due to damage to the heart
muscle, its valves or the conduction system, or to abnormal filling, and is
variously classified by the cause, severity and the side of the heart most affected.
d. Electrical: arrhythmias
Heart failure can arise from the right heart, the left heart or (eventually) both
sides.
In heart failure blood ‘accumulates’ in the vascular territory preceding the failing
chamber: the lungs (left heart failure) and the systemic venous circulation (right
heart failure).
Left heart failure causes congestion (build-up) of blood on the lungs. This gives
rise to fluid exudation in the lungs and pulmonary oedema (so tachypnoea,
shortness of breath, low oxygen saturation, impaired gas exchange on an ABG
and bilateral widespread crackles).
Right-sided heart failure causes a raised central venous pressure in the major
veins of the body (so raised central venous pressure / JVP).
In reality this is a simplistic model and clinical signs may overlap. More typical
heart failure can present with a combination of palpitations, fatigue, syncope,
cough, shortness of breath, respiratory crackles, frothy sputum, orthopnoea,
paroxysmal nocturnal dyspnoea and angina.
Cardiac signs of heart failure include altered pulse rate, rhythm, volume and
character, abnormal blood pressure, cardiomegaly and abnormal heart sounds; in
the hands look for clubbing and cyanosis. Fluid retention presents with
50
pulmonary added sounds, pleural effusion, peripheral oedema, ascites, raised
jugular venous pressure, hepatomegaly and a hepatojugular reflex. Additional
signs include those of high-output conditions – anaemia, thyrotoxicosis,
arteriovenous fistulae and malformations, Paget’s disease, beri beri and
septicaemia.
The clinical signs of moon face, facial acne and a buffalo hump are diagnostic.
The skin is thin with telangectasia, purpuric patches, purple abdominal stretch
marks and hyperhidrosis. The hair is dry and brittle and of male distribution,
often with baldness. Suprasellar extension of pituitary lesions may compress the
optic chiasm, with resultant bi-temporal hemianopia.
51
beats/min, at a depth of a third of the chest (5–6 cm): alternated with 2 rescue
breaths. For effective rescue breaths, create a seal around the mouth, squeeze the
nose and exhale for 1 second, checking for the rise and fall of the chest. Although
CPR is only effective in about 10% of cases, it can delay tissue death until more
advanced life support (intravenous drugs and defibrillation) becomes available.
Successful CPR depends on resuscitation technique, underlying cause of the
cardiac arrest and the patient’s physiological reserve.
10. The resuscitation of the trauma patient must be undertaken according to ATLS
guidelines (Advanced Trauma Life Support) produced by the American College
of Surgeons. All doctors involved in trauma care should gain this qualification.
The following provides a brief summary for finals purposes:
Check for patient response (do they respond if you firmly shake their shoulders
and ask them to open their eyes if they can hear you: shake and shout)
Shout for help / put out the hospital trauma call via switchboard.
1. If there is any suggestion of neck injury, immobilise the cervical spine using a
collar and blocks.
BREATHING – Check for Breathing by holding your ear close to their mouth,
listening and feeling for their breath on your cheek and looking for the rise and
fall of their chest. Check oxygen saturation. Look for evidence of haemothorax,
pneumothorax, flail chest or mediastinal injury (cardiac tamponade, traumatic
aortic dissection). Haemo / pneumothoraces require insertion of a chest drain.
Tension pneumothorax requires initial decompression with a large-bore cannula
in the second intercostal space, midclavicular line. Pericardial tamponade
requires needle pericardiocentesis (aspiration). Major vessel or mediastinal
trauma requires thoracotomy or sternotomy. Further tests: ABG – perform an
arterial blood gas to check the patient’s gas exchange (pH, pCO2, pO2). Are they
in respiratory failure?
52
CIRCULATION – Check for presence of Circulation. Feel a central pulse
(carotid or femoral) – if absent commence CPR and follow the Advanced Life
Support (ALS) algorhythm. Advanced circulation assessment involves checking
heart rate, blood pressure, JVP, heart sounds, peripheral perfusion (warmth and
capillary refill time in the toes). If there is any evidence of external bleeding stop
this by simple manual compression. Insert two large intravenous cannulae and
administer fluid or blood products if the patient is in hypovolaemic shock. Fluid
resuscitation is a much debated subject. In trauma victims, warm fluid should be
used to avoid hypothermia. Overly aggressive fluid therapy may cause already
formed clots in injured vessels to be displaced, having an overall detrimental
effect. Further tests: ECG. Attach to cardiac monitor.
If the patient has obvious major bleeding that will be worsened by CPR, put
pressure on the wound and elevate the limb that is damaged before commencing
the above algorithm. Lay the patient down if possible, and dress the wound(s)
with a maximum of two bandages. If blood seeps through, remove the bandages
and start again.
DISABILITY – Check body temperature and glucose levels. Check for any
evidence of neurological injury: GCS (Glasgow coma scale), pupil size, reaction
and accommodation, gross motor and sensory function of upper and lower limbs.
Further tests: CT scan of the head.
Look for any obvious wounds or bruising indicating penetrating and blunt injury
respectively. Palpate for right upper quadrant pain or masses (liver injury /
haematoma) and left upper quadrant pain (splenic injury / haematoma).
Palpate the pelvis for any evidence of instability or pain suggestive of pelvic
fracture (this can cause major internal bleeding by injuring the iliac vessels).
Look at the penile meatus in men for blood, suggestive of urethral injury
(contraindication for Foley catheterisation).
Perform a log-roll to inspect for injuries to the back and spine; at this time do a
digital rectal examination to assess anal sphincter tone or presence of lower GI
bleeding.
Further tests: FAST scan (focused assessment with sonography for trauma). This
is an abdominal and thoracic ultrasound assessment looking for evidence of free
fluid in the abdomen and chest. Presence of fluid would mandate urgent
operative intervention in unstable patients not fit to undergo formal imaging with
53
a CT scan.
A: any allergies?
L: when did you last eat (to assess risk of intubation / rapid sequence induction
of anaesthesia should it be needed)?
At the end perform a trauma series of X-rays: C-spine, chest and pelvis. Further
imaging is requested once the patient has completed the primary survey.
54
THE HISTORY
Swellings and ulcers are presenting features of many diseases. Always ask the
same questions.
• How does it bother you? (What are the main symptoms: is it painful or tender?)
• Do you have (or have you ever had) any other lumps or ulcers?
THE EXAMINATION
Even if the diagnosis seems obvious, always go through the same routine when
examining a swelling or an ulcer. It is probably easier to talk as you go rather than
to present your findings at the end.

TYPICAL CASES
60
Case 2: wart
Warts are grey/brown filiform lesions, usually seen on the back of the hand. The
surface is rough and the consistency hard.
• Increase in size
• Ulceration
• Change in colour
• Irritation
• Bleeding
• Halo of pigmentation
• Satellite nodules
61
relevant lymph nodes as well as chemoradiotherapy.
Note: squamous cell and basal cell carcinomas can also present as epidermal
nodules. They usually ulcerate and are considered here.
Case 5: dermatofibroma/histiocytoma
This is a firm nodule, usually seen on the lower leg, containing lipid-filled
macrophages. It is part of the skin and fully mobile.
If you are not sure of the diagnosis, ask the patient how quickly it appeared (it
arises within days) and whether he or she remembers a preceding penetrating
injury.
Treatment: excision.
You may be asked about the differences between a keloid and a hypertrophic scar.
62
Treatment:
63
Case 10: sebaceous cyst
This is an extremely common short case. It is usually found in hairy areas (the
scalp, neck, face and scrotum).
The size varies but the lump is usually hemispherical with a well-defined edge.
Although it lies subcutaneously, it is attached to skin by the sebaceous duct, hence
the skin over it cannot be ‘pinched’/elevated.
Always look for a punctum: only 50% will possess one but it is pathognomonic if
found.
If the cyst is painful and red, this does not necessarily indicate infection: after
trauma, the secretions may cause a foreign body inflammatory response in the
surrounding tissues. Bacteria cannot, however, usually be cultured.
If you are asked about its origin, remember that the term ‘sebaceous’ cyst is a
misnomer. It is not derived from the sebaceous gland, but from the outer sheath of
the hair follicle. The cyst contents, although thick and waxy, are dead epithelial
elements rather than sebaceous secretions.
Treatment:
If you are allowed to ask the patient a few questions, ask about diabetes, steroid
therapy and other predisposing immunodeficiencies.
You may be asked to describe the differences between a furuncle and a carbuncle.
64
Treatment: wait for resolution unless cellulitis is present (antibiotic) or abscess
(drain).
Treatment:
5. Wide excision of recurrent lesions, with skin flaps or grafts for closure of
large defects.
You should also be able to recognise the two common paediatric haemangiomas.
65
and may be disfiguring.
Lipomas are usually freely mobile although they may occasionally lie beneath the
deep fascia.
Treatment: excision.
In a child, suspect a congenital dermoid. This occurs at the sites of fusion of the
facial processes, eg the outer angle of the eye.
66
Treatment: excision of whole lesion with primary closure. Prior ultrasound
imaging may be needed in certain lipomas to ensure these don’t extend deep to
muscular planes.
Remember to palpate the ganglion in all positions of the underlying joint: its
mobility depends on whether it is derived from, and thus attached to, deep
structures.
Treatment: excision. Remember ‘hitting with Bible’ – the examiners will, but not
to be recommended.
2. ULCERS
You should know the definition of an ulcer: a defect in an epithelial surface. You
may be asked the causes.
67
Case 18: ulcer with a sloping edge
A sloping edge is characteristic of a healing ulcer, ie a traumatic (although not
neuropathic) ulcer or a venous ulcer.
Venous ulcers are found in the ‘gaiter area’ (above the malleoli, particularly the
medial malleolus). They are usually shallow and flat. The base is covered with
pink granulation tissue mixed with white fibrous tissue.
Look for and describe associated signs of superficial or deep venous insufficiency
(see here).
68
is easily recognised by the yellow-coloured (‘wash-leather’) base. Ischaemic and
neuropathic ulcers are much more common as short cases. They have many of the
same characteristics:
• Deeply penetrating
If you are asked to distinguish between the two, use the scheme in the table
opposite.
The main features distinguishing a basal cell carcinoma (rodent ulcer) from a
squamous cell carcinoma are the edge and the colour.
69
You should be able to list the predisposing factors for skin cancer:
• Age
• Ionising radiation
Remember that malignant change (usually to squamous cell carcinoma) can also
occur in long-standing benign ulcers (Marjolin’s ulcers), in scars and in chronically
discharging osteomyelitis sinuses.
Treatment of ulcers:
• Neuropathic – daily inspection of feet, protect against trauma, clean and bandage
• Malignant – excise lesion together with draining lymph nodes; chemotherapy and
radiotherapy as adjunctive or palliatve options

THE HISTORY
If your patient complains of a swelling in the neck, ask the same questions as for
any lump (here).
• Do you have any pain or discharge from your nose or ears? Do you have a sore
throat?
• Have you noticed any other lumps on your head or face? Do you have any
difficulty swallowing?
73
Eye problems associated with hyperthyroidism
1. General symptoms
2. Gastrointestinal symptoms
3. Cardiorespiratory symptoms
4. Neurological symptoms
THE EXAMINATION
A common instruction in the short case is to ‘examine this patient’s neck’ without
being given any clue as to the pathology. Alternatively, you may be asked to
‘examine this patient’s thyroid gland’. In this case, proceed to the relevant section
of the examination scheme below. Rarely, you may be pointed out a lump and asked
to describe it (pages here).
74
The presence of a glass of water near the patient is a good hint that there may be a
goitre!

TYPICAL CASES
81
You should memorise a list of midline neck swellings as shown below.
Case 1: goitre
Revise the causes of a goitre.
a. Physiological
• Puberty
• Pregnancy.
Note: these have the same underlying pathogenesis and a multifactorial aetiology:
• Goitrogens
• Dyshormogenesis
• Autoimmune.
• Hashimoto’s thyroiditis
• Graves’ disease.
d. Other thyroiditides
82
e. Tumours
• Benign
f. Other
• Tuberculosis
• Sarcoidosis.
Note that if you feel a single nodule you may be feeling the following:
You may be asked about the different kinds of primary thyroid cancers shown
below.
Assess thyroid status independently: you are expected to know the common causes
of hyper- and hypothyroidism.
83
Investigation: determine levels of TSH, T3 and T4 (euthyroid: normal TSH;
hyperthyroid: TSH T3 ; hypothyroid TSH n T4 ), thyroid antibodies for
thyroiditis, ultrasonography to differentiate cystic and nodular disease, CT and MRI
to identify infiltration, fine-needle aspiration and histological examination.
Treatment:
2. Remove goitrogens.
84
Case 2: thyroglossal cyst
This is a spherical midline lump. It feels hard and the edge is clearly defined. It
moves with swallowing, but ask the patient to stick out his or her tongue: the lump
will move up due to its attachment to the fibrous remnants of the thyroglossal tract;
this differentiates it from a thyroid mass.
Treatment: excision of cyst and whole tract. This may loop behind the hyoid bone,
requiring resection of the body and following the tract into the base of the tongue.
aNote: a cold abscess arises from TB involvement of the nodes: the caseating nodes
point, weakening the overlying tissue and then burst, causing a ‘collar-stud’
85
abscess.
a. Infection (sialoadenitis)

i. Malignancy
• Benign
• Intermediate
• Malignant.
Remember:
The most likely cause of parotid enlargement is a benign mixed parotid tumour.
Occasionally you will see a Warthin’s tumour. The following characteristics
distinguish these two tumours.
You may be asked how you would clinically assess the malignancy of a parotid
tumour. The distinguishing features are:
• Short presentation
• Painful
• Hard consistency
88
• Irregular surface and indistinct edge
The lump is only occasionally palpable, just above the clavicle. It may be pulsatile
due to the elevated and sometimes dilated subclavian artery.
• Raynaud’s phenomenon
• Rest pain
• Trophic changes
• Gangrene.
89
shown in the figure below.
You may feel pulsation. This may result from the following sources:
Ask about blackouts, transient paralysis and paraesthesia. Check the other side –
the tumour is often bilateral.
The cyst has a distinct edge and a smooth surface. Depending on its contents, it may
or may not transilluminate.
You may be shown a branchial sinus or fistula – a small dimple in the skin, at the
junction of the middle and lower thirds of the anterior edge of sternomastoid:

92
ANSWERS
1. (a) Infection: from the skin of the head and neck, the tonsils, adenoids and throat,
other sites in the ear and nose, paranasal air sinuses, pharynx and larynx. (b) Part
of generalised lymphadenopathy: acute (eg infectious mononucleosis,
cytomegalovirus) or chronic (eg TB, brucellosis, secondary syphilis, HIV). (c)
Malignancy: primary (eg lymphoma, Hodgkin’s lymphoma and leukaemias) or
secondary (eg metastases from carcinoma of the head and neck, breast, chest and
abdomen). (d) Amyloid and sarcoid infiltration.
2. The anterior triangle lies anterior to the sternomastoid muscle below the
mandible. The triangles from each side meet in the midline. Lymph nodes and
abscesses such as tuberculous ones, salivary glands (submandibular and
parotid), carotid body tumours, carotid aneurysms, branchial cysts and tumours
of the sternomastoid.
93
6. Continuation of long-term carbimazole or other anti-thyroid agents; additional
propranolol in severe cases and uncontrolled cardiovascular symptoms; Lugol’s
iodine 2 weeks preoperatively.
10. Stenosis in the duct due to chronic infection and oral disease around the papilla.
They usually occur in the submandibular gland, leading to pain and distension
on eating; very rarely found in the parotid gland.
12. Benign: smooth, lobulated, painless, may be bilateral, when superficial may be
slightly mobile, usually soft to firm, slowly enlarging over years. Malignant:
firm to hard, fixed, rapid growth over a number of months, facial nerve
involvement and infiltration of surrounding tissues.
13. Facial nerve injury (which may be unavoidable in treating malignant disease),
Frey syndrome, gustatory sweating due to divided parasymphathetic nerves
growing into the skin, salivary fistula, recurrence of malignancy.
94
Your patient in either the long or short case might be a woman complaining of pain
(cyclical, persistent, progressive) or a lump in her breast.
THE HISTORY
Bring out the following points when presenting under ‘history of presenting
complaint’.
Breast lump
• When did you notice the lump? How did you notice it?
• Has the lump changed since you first noticed it? How?
• Is it painful?
Hormonal factors
• Does the lump change with your menstrual cycle or at different times in the
month?
• When did you start your periods? (menarche) If relevant – When did you stop
your periods? (menopause)
95
• How many children do you have? Did you breast-feed them? Were there any
problems?
Nipple discharge
• Spontaneous or elicited
THE EXAMINATION
The usual instruction given in the short case is to ‘examine the breasts’. Proceed as
below (a chaperone should be present, and may be requested).
Occasionally, you may be asked just to feel and describe a lump in the breast, in
which case you should proceed as described on pages here. Remember at all times
to be sensitive and to avoid embarrassment and discomfort. Cover the breasts up
when you are examining other systems.
96
97
98
TYPICAL CASES
Breast lumps come up as long (OSLER) and short (OSCE) cases. Revise the causes
of a breast lump.
99
You should be able to differentiate clinically between the more common lumps.
a. Age 35+
c. Lump
• Stony-hard
• Irregular edge
• Immobile
• Peau d’orange.
d. Nipple

e. Lymphadenopathy
f. Features of metastases
• Backache
• Breathlessness
• Jaundice
Remember that the signs of breast carcinoma may be mimicked by other conditions.
Consider the following:
101
Screening: in the UK all women aged 50–70 are invited for breast cancer screening
every 3 years. This involves a bilateral breast X-ray (mammogram). This aims to
detect breast cancers early and offer curative surgical treatment.
Stage 1: early disease confined to the breast (T1 <2 cm) or Paget’s disease
Stage 2: axillary nodal spread (T2 2–5 cm, N1); stages 1 and 2 are classified as
early disease
Stage 3b: chest wall involvement (T3 <5 cm, T4 skin and chest wall involvement,
N2 fixed nodes, N3 ipsilateral internal mammary nodes)
102
lymph nodes showing high isotope uptake (hence predominant tumour drainage).
This technique is known as sentinel lymph node biopsy. It aims to prevent the co-
morbidities associated with axillary clearance (eg arm lymphoedema) or
unreliability of axillary sampling.
a. Chemotherapy
The Nottingham Prognostic Index (NPI) uses: the size of the lesion; tumour grade;
number of involved lymph nodes. A score of ≤ 3.4 with the system suggests an 85%
5-year survival and > 5.4 a 50% survival rate.
Case 2: fibroadenoma
A woman with a fibroadenoma will usually be young (peak 25–35 years).
There may be more than one lump. The lumps are small and rubbery-hard. They are
very mobile and are therefore also known as ‘breast mice’.
Treatment: refer to specialist breast unit for triple assessment. Excision biopsy
may be subsequently recommended to exclude malignancy, although simple, low-
risk lesions that have been triply assessed can be monitored radiologically.
Case 3: fibroadenosis
Terminology varies: aberration of normal development and involution (ANDI) most
accurately describes the process.
103
It occurs in women of reproductive age, peak 35–45 years. Ask specifically about
variation with the menstrual cycle.
Eczema, Paget’s disease and fistulae all cause discharges that do not arise from the
ducts themselves.
• Spontaneously
• Unilateral discharge
• Bloody discharge
104
• Discharge arising from a single duct (single nipple segment). The colour of the
discharge may give you a clue as to the cause.
105
FAQS AND POPULAR VIVA QUESTIONS
1. What is a fibroadenoma?
3. What benign breast diseases come into the differential diagnosis of breast
cancer?
10. How would you manage a woman with early breast cancer?
11. What are the advantages of lumpectomy over mastectomy for breast cancer?
106
ANSWERS
1. A focal area of lobular stromal hyperplasia with epithelial proliferation.
4. Mammography screening of the female population at age 50–70 may detect non-
palpable asymptomatic disease. Serial assessment at 3-year intervals may
identify early malignant change. Abnormalities are detected by specialist teams.
Triple assessment (clinical, imaging, tissue sampling) is recommended.
6. Local spread may distort the nipple, tethering to skin may produce peau d’orange
and deep tethering may cause fixation. Nodal spread is to the axilla and is
frequently to the internal mammary nodes. Vascular spread is primarily to the
liver, lung and bone.
8. Bloody discharge from a ductal papilloma and carcinoma; green cell debris from
fibroadenosis and duct ectasia; yellow exudate from fibroadenosis and
abscesses; milk from the lactating breast. Cutaneous discharge may arise from
eczematous change.
9/10.
Early breast disease is stage 1 (TI: a tumour of <2 cm) and stage 2 (T2: 2–5 cm);
if axillary nodes are present, they must be mobile. Treatment involves complete
local excision of lesions of <5 cm as well as radiotherapy to the conserved
107
breast; after initial sentinel node biopsy and frozen section, a decision is made
on axillary surgery; axillary clearance below the axillary vein and medial to the
pectoralis minor muscle.
12/13.
Advance cancer is stage 3 (tumours of >5cm: T3), or extension into the skin or
chest wall (T4). Axillary nodes are fixed (N2), ipsilateral internal mammary
nodes are present (N3) and stage 4 extension beyond the breast and chest wall
(M1). Treatment is based on national guidelines and involves a multidisciplinary
team, it may include radiotherapy, endocrine therapy and chemotherapy directed
at symptomatic, local and distal sites.
108
THE HISTORY
Give a succinct and chronological report of your patient’s presenting complaint.
Bring out the following aspects in your presentation.
• Dysphagia/dyspepsia
• Abdominal swelling/distension/pain
• Jaudice, pruritis
109
• Overseas travel
Remember that diarrhoea/constipation are not precise words: ask what is normal
for your patient.
• ?consistency
• ?frequency, quantity
• ?colour
• ?offensive
• ?mucus/slime
THE EXAMINATION
Listen carefully to the instruction. In a short case, you may be asked to ‘examine the
gastrointestinal system’ or ‘examine the abdomen’.
As with the examination of any system, always start with the hands. You may be
stopped at this stage and asked to proceed to the abdomen itself. Occasionally, you
may be instructed to ‘palpate the abdomen’, in which case beginning with the hands
will only antagonise the examiners.
• Don’t hurt your patient: ask if an area is tender during palpation; keep looking at
his or her face for wincing.
110
– percussion of the upper border of the liver (normally fifth intercostal space;
may be displaced downwards with hyperexpansion of the chest)

114
115
116
TYPICAL CASES
You are unlikely to meet a patient with an acute abdomen in either the short or the
long case. However, you should revise the causes of acute abdominal pain for
discussion in the clinical examination and viva.
In the long case, you may meet patients with abdominal symptoms but few signs.
Examples are patients with peptic ulcers, chronic cholecystitis (and bouts of biliary
colic), chronic pancreatitis, diverticular disease, irritable bowel syndrome and
inflammatory bowel disease.
You may also have a patient with jaundice. In a surgical examination, the most
likely cause will be post-hepatic ‘obstructive’ jaundice. However, when asked the
differential diagnosis, mention pre-hepatic and hepatocellular causes.
The main physical signs, to be picked up in both the long and the short case, are
scars and stomas, organomegaly, masses and distension. This section revises the
differential diagnosis of these signs.
Scars
Always look very carefully for abdominal scars: old ones are surprisingly easy to
miss, especially in hirsute men. It is particularly easy to miss a Pfannenstiel
117
incision, appendicectomy scar and a left nephrectomy scar (look well over the left
loin).
Short (1–1.5-cm) scars in the umbilical region, along the midline and elsewhere
may indicate laparoscopic procedures.
Stomas
You should understand the differences between ileostomies and colostomies.
2. ORGANOMEGALY
Case 1: hepatomegaly
In a surgical examination, the most common cause of hepatomegaly is metastases.
The patient may or may not be jaundiced. Your examiner will expect you to know
the other causes of hepatomegaly.
118
Common causes in the UK include the following:
• Metastases
• Cirrhosis (not in later stages, when liver shrinks and its impalpable)
• Hepatatis
• Hepatocellular carcinoma
• AV malformation
Case 2: Splenomegaly
If your patient has splenomegaly, you may well be asked to justify your diagnosis in
terms of its five distinguishing characteristics:
119
2. Moves down on inspiration
5. Dull to percussion (continuous with area of splenic dullness over ribs 9, 10 and
11, behind posterior axillary line).
Have a list of causes of massive, moderate and mild splenomegaly. As always, give
the common causes in the UK first (eg myelofibrosis rather than kala-azar for
massive splenomegaly).
Although many of these causes of splenomegaly are ‘medical’, your patient may be
awaiting a splenectomy because of its complications: hypersplenism leads to both
pooling and destruction of haematopoietic cells by the reticuloendothelial system,
causing a pancytopenia. Be aware of the potential problems of splenectomy, eg
infection with capsulated bacteria such as pneumococci. Know about the measures
to reduce such complications (Pneumovax immunisation, prophylactic penicillin).
See Treatment following Case 3.
Case 3: hepatosplenomegaly
Causes of enlargement of the spleen as well as the liver include some of the above,
eg lymphoma, leukaemias, infections, amyloidosis and sarcoidosis. The most likely
case in an examination is cirrhosis with associated portal hypertension.
Treatment for Cases 1, 2 and 3: management of most of the listed diseases is that
of the underlying cause. Surgery for hepatomegaly might include drainage of
120
abscesses, segmental resection of tumours and occasionally transplantation.
Indications for splenectomy include septicaemic abscesses, schistosomiasis,
tropical splenomegaly, hydatid cysts, Gaucher’s disease, myelofibrosis,
thalassaemia, sickle cell disease, lymphoma, embolic infarction, splenic artery or
venous thrombosis, and possibly hereditary spherocytosis, idiopathic
splenomegaly, thrombocytopenic purpura and solitary or polycystic disease.
• Descends vertically
• Resonant to percussion due to overlying colon (not always: some parts may be
dull)
121
• Take the blood pressure
• Ask to examine the urine (?haematuria, ?proteinuria, ?casts) – try to palpate the
liver, which might also be polycystic
• Look for a third cranial nerve palsy due to pressure from an associated posterior
communicating artery berry aneurysm.
• Hydronephrosis
• Hypertrophy
3. MASSES
Revise pages 41–43 for the description of any mass.
As many masses are visible on careful observation of the abdomen, do not forget to
look first.
List and revise the causes of masses in each segment of the abdomen.
• Hepatomegaly
122
• Enlarged gallbladder
• Colonic mass.
b. Obstruction of the common bile duct, eg cancer of the head of the pancreas.
‘If the gallbladder is palpable and the patient is jaundiced, the obstruction of the
bile duct causing the jaundice is unlikely to be due to a stone.’ The gallbladder is
fibrotic and contracted in inflammatory (non-malignant) disease.
• Appears from the tip of rib 9 and cannot get between it and the liver edge
• Dull to percussion
• Smooth surface
2. Large recti: these appear to enlarge when the patient sits forwards.
123
3. Prominent xiphisternum: comes to light at odd ages.
• Hard, irregular
• Resonant to percussion
• Enlarged liver
124
• Enlarged gallbladder.
• Aortic aneurysm.
• Enlarge spleen.
Investigations for Cases 5–10: confirmation of the diagnosis in these areas can
usually be obtained by imaging techniques. CT and MRI provide reliable
diagnostic information on the liver, spleen, pancreas, kidneys and retroperitoneal
structures, identifying inflammatory change as well as benign and malignant
tumours, with or without invasion and secondary spread.
125
The most common causes are carcinoma of the caecum and Crohn’s disease.
a. Carcinoma of caecum
Suspect this condition in an elderly patient who appears clinically anaemic. The
mass is often well defined and hard. It can be mobile or fixed. It is not usually
tender.
b. Crohn’s disease
This is usually seen in younger patients. The mass feels rubbery and non-tender and
can be fairly mobile. See Treatment following Case 12.
• Appendix mass
• Ileocaecal TB
• Iliac lymphadenophaty
• Ovarian cyst
• Ectopic pregnancy
• Transplanted kindey
a. Diverticular disease
126
b. Carcinoma of colon
The patient normally presents with a change in bowel habit. The mass is usually
hard.
Feel for an enlarged liver and listen for high-pitched bowel sounds (in the presence
of any obstruction); palpate for enlarged inguinal nodes.
Treatment for Cases 11 and 12: most iliac fossa masses are related to lesions of
the colon. Appendix abscesses may require drainage. Those extending laterally are
allowed to resolve, followed, after a few months, by interval appendicectomy.
Medial extensions may give rise to further gut symptoms and may require a difficult
surgical resection in the acute phase.
Crohn’s disease may require drainage of abscesses and resection of fistulae. The
aim is to preserve as much bowel as possible.
2. Flatus: the abdomen is hyper-resonant; you may see visible peristalsis, implying
bowel obstruction.
3. Faeces: you are unlikely to be given a patient with acute obstruction. However,
chronic constipation is a common surgical problem. Beware – your patient may
be complaining of diarrhoea and in fact be constipated (spurious diarrhoea).
Faeces have the following characteristics:
127
– can be indented with digital pressure.
5. Fluid: ascites can be detected by two tests: fluid thrill and shifting dullness. The
latter is more reliable because a fluid thrill is detected in any abdominal fluid-
filled cavity.

11. How does the presentation of carcinoma of the right side of the bowel differ
129
from that of the left?
130
ANSWERS
1. Dysphagia may be due to abnormalities of the wall or the lumen of the
oesophagus, or extrinsic pressure. Strictures of the wall include benign and
malignant neoplasms, acute and chronic oesophagitis, Crohn’s disease, post-
radiotherapy, oesophageal diverticula and scleroderma. Abnormal contracture
occurs in achalasia, abnormal relaxation of cricopharyngeus and Chagas’
disease. Abnormalities within the lumen include foreign bodies and webs.
Extrinsic pressure can be from a goitre, pharyngeal pouch, aortic aneurysm or
abnormal aortic arch vessels, mediastinal tumours and a paraoesophageal hiatus
hernia.
131
spherocytosis, hypersplenism), hepatic causes (liver dysfunction: hepatitis,
cirrhosis, Gilbert’s disease) and post-hepatic causes (obstruction to the biliary
tree caused by gallstones, benign and malignant strictures, sclerosing
cholangiitis, extrinsic neoplasms in the porta hepatis and head of pancreas).
Haematemesis and melaena: melaena is the name for the black stool resulting
from the digestion of blood from luminal bleeding in the upper intestinal tract.
When this bleeding is profuse and from the proximal duodenum and above, it
may be vomited as haematemesis. Thus, haematemesis and melaena have a
common aetiology above this level. Oesophageal bleeding must be
differentiated from haemoptysis and can result from most of the inflammatory and
neoplastic causes of dysphagia listed above. Other causes of oesophageal
bleeding include trauma after endoscopy, ingestion of foreign bodies and
vomiting leading to tearing of the mucosa at the oesophageal junction (Mallory–
132
Weiss tear). Some of the most severe bleeding is from oesophageal varices in
liver failure and fatal bleeding occurs when an aortic aneurysm erodes into the
oesophagus. Gastroduodenal haematemesis is usually due to peptic ulceration but
may be caused by multiple gastric erosions and benign and malignant neoplasms.
In the small gut, ectopic gastric mucosa may be present in Meckel’s diverticulum
or duplicated gut, causing melaena. Aortoduodenal fistulae and fistulae from
infected prosthetic arterial grafts in the abdomen can also cause melaena.
Obstruction: in children may be related to atresia along the length of the gut
(oesophageal, pyloric, small gut, Hirschsprung’s disease and imperforate anus,
duodenal or Ladd’s bands, annular pancreas, meconium ileus, midgut volvulus,
strangulated hernias and intussusception. Adult obstruction may result from
adynamic or dynamic causes. Adynamic causes include paralytic ileus, acute
ischaemia, megacolon and Hirschsprung’s and Chagas’ diseases and pseudo-
obstruction. Dynamic causes include lesions of the wall, lesions within the
lumen and external compression. Lesions within the gut wall include diverticular
disease, inflammatory bowel disease, carcinoma and anastomotic strictures.
Luminal obstruction may be due to faecal impaction and gallstone ileus. The
most common causes of external compression are adhesions and hernias. Other
causes of external compression include volvulus, bands and the spread of
neoplasia throughout the peritoneum and pelvis.
Pruritis ani is caused by excess sweating and poor local hygiene, skin
conditions (eczema, contact dermatitis, allergy, psoriasis, lichen planus),
infective lesions (sexually transmitted infections, fungal, scabies, lice,
threadworms, Candida spp., Trichomonas spp.). Other causes include anal
pathology (piles, fissures, fistulae, warts and pilus adenomas, solitary ulcers and
other anal neoplasms), diarrhoea/incontinence (sphincter malfunction, rectal
prolapse, leakage of liquid paraffin), generalised causes of itching (obstructive
jaundice, diabetes mellitus, hypoparathyroidism, myeloproliferative disorders
and lymphomas) and psychological causes. In babies, pruritis ani is most
133
commonly due to nappy rash as a result of infrequent changes and reaction to
local applications.
5. Pancreatic carcinomas are usually slow growing. There is often vague, deep
abdominal or back pain. Diagnosis may be late, when they have already invaded
adjacent structures, such as the large vessels, spleen and the lesser sac.
Carcinomas of the head, however, may involve the common bowel duct and
investigation of the resulting progressive jaundice results in an earlier diagnosis.
134
diet low in roughage and high in refined foods. Over half the population over the
age of 50 are affected. Diverticulitis indicates a superadded infection.
8/9.
Crohn’s disease and ulcerative colitis collectively are termed ‘inflammatory
bowel disease’ and may cause intrinsic or extrinsic lesions. The gut lesions
(colitis) is primarily ulceration of the mucosa and submucosa of the colon and
rectum. Long term, the lesions are prone to malignant change. Crohn’s disease is
associated with full-thickness inflammation of the gut wall with fissuring and
skip lesions, and mainly involves the small bowel, but also the large bowel and
the perianal region and can involve the entire gastro-intestinal tract. It typically
involves adjacent structures such as the gut, urinary tract, vagina and skin.
Ulcerative colitis is associated with prominent diarrhoea and occasionally
fulminating toxic megacolon.
10. Dukes’ A: neoplasm confined to gut wall; Dukes’ B: spread through gut wall;
Dukes’ C: nodal involvement. Later subclassifications included Dukes’ C1 and
C2, referring to the involvement of nodes around the inferior mesenteric artery,
and Dukes’ D for metastatic spread.
11. Lesions of the capacious right colon where faecal material is more fluid usually
present with anaemia. Lesions of the left colon may present with an alteration in
bowel habit and/or obstruction. Both may present with a palpable mass or
spread to the adjacent peritoneum, leading to an inflammatory mass or
135
perforation. Both may also present with signs of secondary spread to the liver.
12. The features of intestinal obstruction are colicky abdominal pain, vomiting,
abdominal distension and absolute constipation.
136
THE HISTORY
Hernias and groin lumps are very popular short and OSCE cases. After examining a
hernia, you may be instructed to ask the patient some additional questions. Structure
them as follows.
Predisposing causes
• Do you have to strain to pass a motion? (Note that this can occur with both
constipation and diarrhoea.)
137
• Have you noticed your abdomen swelling/your clothes getting tighter?
THE EXAMINATION
In a short case, you may be asked specifically to ‘examine this hernia’ or ‘this
scrotal lump’, in which case you should examine as for any lump (here) plus
perform the additional assessment outlined below. If you are asked to ‘examine the
groin’, follow the whole examination scheme.
• You may see an inguinal lump that you are certain is a hernia. However, always
examine the scrotum as well. There might be dual pathology.
• Try to distinguish between a direct and an indirect inguinal hernia. Some say that
this is unimportant because it does not affect the patient’s management. However,
you cannot be faulted for being too thorough.
138
TYPICAL CASES
139
INGUINAL SWELLINGS AND HERNIAS
One way to remember the differential diagnosis of lumps in the groin is to think of
the structures that normally lie in the region.
a. Hernias
• Femoral.
b. Vascular structures
• Saphena varix
• Femoral aneurysm.
c. Lymph nodes
• Lymphadenopathy.
d. Muscle
• Psoasabscess.
e. Hip joint
• Psoas bursa.
f. Testis
g. Spermatic cord
Have a clear picture of the relationship of these structures to the inguinal ligament.
140
You may be asked what is meant by the term ‘hernia’. The definition should roll off
your tongue:
‘The protrusion of the whole or part of a viscus, from its normal position, through
an opening in the wall of its containing cavity.’
Note that strangulation can occur without obstruction if only one wall of a viscus
pouches into the sac (‘Richter’s hernia’).
However, a favourite question is to describe the anatomy of the inguinal canal: this
is an intermuscular oblique passage, 4-cm long. The following structures pass
through it:
• Ilionguinal nerve.
141
a. The walls
b. The rings
External ring
This is formed by the two crura of the external oblique aponeurosis (ie it is an
opening in the external oblique). It lies just above and medial to the pubic tubercle.
Internal ring
This is a U-shaped condensation of the fascia transversalis (ie it is an opening in
the fascia transversalis).
It lies just above the midpoint of the inguinal ligament. The inferior epigastric
artery (branch of external iliac) runs medially.
Note the difference between the midpoint of the inguinal ligament (halfway
between the ASIS and the pubic tubercle) and the midinguinal point (halfway
between the ASIS and the pubic symphysis – landmark of the femoral pulse). The
midpoint of the inguinal ligament lies 1–1.5 cm lateral to the midinguinal point.
142
Understand the anatomy of direct and indirect hernias:
Some examiners are keen for you to be able to distinguish clinically between a
direct and an indirect hernia:
143
Case 2: femoral hernia
You should know how to distinguish a femoral from an inguinal hernia clinically.
aA femoral hernia may bulge up into the groin crease (as shown here).
• In both men and women inguinal hernias are more common than femoral hernias.
However, femoral hernias. However, femoral hernias are more common in
females than in males.
• A femoral hernia is more likely to obstruct and strangulate than an inguinal hernia
because of the narrow femoral ring. Furthermore, a femoral hernia is more likely
than an inguinal hernia to strangulate without obstructing (Richter’s hernia).
Treatment: femoral hernias have a narrow neck and are particularly prone to
strangulation, possibly of the Richter variety. They therefore require early surgery
and complications should be treated as an emergency. After inspecting the contents
of the sac, ligating its neck and removing excess, repair is by suture of the inguinal
ligament to the pectineal ligament, the fibres of which run along the superior ramus
of the pubis. Two or three sutures are placed with a J-shaped needle and ligated
from medial to lateral to ensure that the femoral vein is neither damaged nor
144
compressed.
The table below summarises the clinical features of some other inguinal swellings
(Cases 3–6).
Treatment:
Case 3
A saphena varix is treated as part of varicose vein excision in symptomatic
patients.
Case 4
Femoral aneurysm is treated by surgical resection and replacement with a synthetic
tube (graft) oral endovascular approach.
Case 5
Lymph nodes may be part of a generalised infection. In localised infection the
source must be identified and treated. Tuberculous nodes require treatment with a
full course of antituberculous therapy. Primary and secondary malignant nodes
145
require a tissue diagnosis. This might be possible through fine-needle aspiration, a
full search being undertaken to identify a primary site, so that treatment of primary
and secondaries can be planned.
Case 6
Psoas abscesses are drained and appropriate antituberculous therapy initiated.
146
FAQS AND POPULAR VIVA QUESTIONS
1. Define ‘hernia’.
4. What are the surface markings of the superficial inguinal ring/the deep
inguinal ring?
147
ANSWERS
1. A protrusion of the whole or part of a viscus from its normal position, through an
opening in the wall of its containing cavity.
2. (a) Lumbar hernia: through a defect in the lateral abdominal wall, above the
iliac crest between the posterior border of external oblique and the anterior
border of latissimus dorsi. (b) Umbilical hernia: through a congenital defect in
the umbilicus. (c) Paraumbilical hernia: through the linea alba, adjacent to the
umbilicus. (d) Incisional hernia: through an old incision. (e) Spigelian hernia:
through a defect in the lateral border of the rectus sheath, usually just below the
umbilicus. (f) Internal abdominal hernias: through the oesophageal hiatus and
other diaphragmatic congenital openings.
4. The superficial inguinal ring is situated above and medial to the pubic tubercle
and is an opening in the external oblique aponeurosis. The deep inguinal ring is
situated just above the midpoint of the inguinal ligament and is an opening in the
transversalis fascia.
5. The inguinal canal extends from the deep to the superficial inguinal rings as
described in (4). Posterior relations: the transversalis facia and medially
conjoined tendon and inferior epigastric vessels passing upwards and medially
on the tranversalis fascia. Anterior relations: the external oblique and laterally
the internal oblique. Inferior relations: the inguinal ligament and medially the
lacunar reflection of the inguinal ligament. The internal oblique arches over the
canal to become the conjoined tendon.
6. The neck of the femoral canal is situated lateral to the lacunar ligament, medial
to the femoral vein, with the inguinal ligament anteriorly and the superior pubic
ramus posteriorly. The canal passes downwards beneath the fascia lata to the
saphenous opening. Hernias pass along this pathway and through the opening,
148
alongside the vein. As a result of the attachment of the superficial facia to the
inferior margin of the saphenous opening, femoral hernias are then directed
upwards anterior to the inguinal ligament in the groin.
7/8.
Two serious complications of hernias are obstruction and strangulation. In
obstruction, constriction of the neck of the sac leads to obstruction of the loops of
small bowel within it. In strangulation, constriction of the venous return leads to
congestion, arterial occlusion and gangrene, with the potential of perforation,
causing peritonitis or a groin abscess. In Richter’s hernia, a bulge of one wall of
the viscus into the hernial sac may become strangulated without producing
obstruction of the involved bowel loop.
9. An indirect hernia passes along the inguinal canal within the spermatic cord and
its congenital defect. A direct inguinal hernia is through a weakness of the
transversalis facia in the posterior wall, the hernial sac passing medially through
the superficial inguinal ring alongside the spermatic cord.
10. Herniotomy involves the opening of the hernial sac, the inspection of its
contents, their replacement within the abdominal wall, ligation of the neck and
removal of excess tissues. In herniorrhaphy, there is additional repair of the
abdominal wall defect. In children, where the superficial and deep inguinal rings
almost overlap, a herniorrhaphy is unnecessary because, in the subsequent
development of the inguinal canal, the external and internal oblique muscles
come to overlay the herniotomy site.
11. An incision is made over the strangulated loop of gut, the sac is opened,
infected peritoneal fluid is evacuated, and the strangulated loop is examined to
assess its viability and the need for resection. Care must be taken not to lose a
strangulated loop or strangulated side wall of bowel back into the abdomen
without it being fully examined. If there is any doubt about this happening, or if
the resection cannot be carried out through the hernial sac, a separate laparotomy
incision is also required.
149
Urological cases present in the clinical with renal (here) and scrotal swellings
(here); malignancy and infection of the renal tract and prostatic problems are not
commonly associated with other abnormal physical signs. You should, however, be
able to take a urological history, and know about the symptoms of prostatism and
urinary tract infection, and the management of urinary catheters.
• Frequency: note the number of times that the bladder is emptied during the day
and night (D/N)
• Abdominal pain: suprapubic – usually cystitis; renal colic, loin radiating to groin
– calculi; loin – renal disease
150
• Haematuria: start, mixed or end of stream/frank blood; painful – usually
infection; painless – malignancy must be excluded
Examination includes looking for nephrectomy and suprapubic scars (see here); the
loins for renal masses (see here, Cases 8 and 10, and here, answer 1); the iliac
fossae for transplanted kidneys (see here, Case 11, and here, answer 5); and the
scrotum (see below): tell the examiner that you would always add a rectal
examination in your clinical practice. A general examination (see here) is an
essential part of the assessment of all renal disease and malignancies of the renal
tract, because there might be abnormal systemic signs (at the end ask for dipstick).
151
Case 1: suprapubic mass
Suprapubic masses are easily missed. The two characteristics of a pelvic swelling
are:
The most common cause is an enlarged bladder. This has the following
characteristics:
• Dull to percussion
• Fluid thrill
In the female, do not forget obstetric and gynaecological causes: the most frequent
pelvic mass in the female is the pregnant uterus. Also consider a large ovarian cyst
and uterine fibroids.
152
is preserved in the premenstrual years, but ovarian cancer requires extensive
clearance, as well as a chemotherapeutic approach. Uterine cancer, fibroids and
other lesions may require hysterectomy with or without oophorectomy.
A simplified diagnostic flowchart that excludes the latter two conditions is given
below.
Note that lymphatic spread is along the site of its embryological origin, ie to para-
aortic lymph nodes. It spreads to inguinal nodes only if the scrotum is invaded.
153
α-fetoprotein (50% in teratoma) plus alkaline phosphatase (50% in seminoma). CT
is undertaken to identify para-aortic or mediastinal lymph nodes or secondaries in
the liver or lungs.
Case 2: varicocele
This is a dilatation and elongation of the pampiniform plexus of veins, usually
found on the left.
154
Case 3: hydrocele
This is a swelling that cannot be felt separately from the testis. It is fluctuant and
transilluminable. It is due to excessive fluid collecting in the tunica vaginalis.
Understand the anatomy of the four types of hydrocele. All of these come into your
differential diagnosis of inguinal and inguinoscrotal lumps. A vaginal hydrocele is
by far the most common. The features of the four types of hydrocele are summarised
in the table overleaf.
155
Case 4: epididymal cyst
Similar to a hydrocele, this is brilliantly transilluminable. However, the testis can
be felt separately.
Note that if it is filled with many sperm it can be opaque. In this case, it is called a
spermatocele.
Treatment: usually conservative but cysts might be excised if they are producing
symptoms; care is taken not to damage surrounding structures because this can
impair fertility.
Look carefully for other swellings in the area; there may be an ectopic testis. You
may feel a lump in the following positions:
• Perianally.
Once you have excluded retractile and ectopic testes, you can diagnose an
incompletely descended testis.
Treatment: undescended testes usually descend into the scrotum by the age of 2
years. Orchidopexy is undertaken after this age as (1) infertility is likely after
puberty, (2) the testes are more likely to undergo torsion and (3) the testes have a
tenfold increased incidence of malignancy. The testes may lie in the inguinal canal
or just above (identification may be helped by CT). The spermatic vessels are
preserved but other restricting tissues are excised to allow the testes to reach the
scrotum. Ectopic testes are similarly mobilised and placed within the scrotum.

5. What clinical signs would indicate that a patient has had a renal transplant?
11. A man is found to have a craggy prostate on attending the clinic with back
pain – how do you proceed?
158
ANSWERS
1. The differential diagnosis for a left upper quadrant mass includes:
a. Renal: renal cysts, renal cancers / metastases, hydronephrosis, perinephric
abscess
b. Spleen: splenomegaly, splenic artery aneurysm
c. Colon: colon tumour
d. Stomach: gastric tumour.
An enlarged spleen:
a. On palpation is not ballotable
b. On palpation has a medial notch
c. On palpation one ‘cannot get above it’ (upper edge is hidden by thoracic cage)
d. On inspiration: descends diagonally towards right iliac fossa
e. On percussion it is dull.
159
and pelvis for staging.
Treatment for renal cell carcinoma is radical nephrectomy. Small lesions
under 4 cm may be amenable to partial nephrectomy. Radiation and
chemotherapy have poor results. Immunotherapy requires further investigation,
although it has produced encouraging results in select patient groups.
8. Causes of haematuria:
a. Tumours: renal cell carcinomas, bladder transitional cell carcinomas, prostate
adenocarcinoma
b. Trauma: post insertion of Foley catheter, after cystoscopy or after urethral
injury in pelvic fractures
c. Infection: cystitis, prostatitis
d. Inflammation: nephritic syndrome
e. Mechanical: urinary stones
f. Medical: coagulopathies
g. ‘Red herrings’: ingestion of beetroot, jaundice causing dark urine.
160
b. Changes in urinary stream if the tumour involves the bladder outlet
c. Abdominal or pelvic masses associated with inguinal lymphadenopathy
(rarely found in early lesions).
11. In a patient with a craggy (enlarged / irregular) prostate and back pain you have
to suspect a diagnosis of prostate cancer with bone metastases:
a. As for any condition take a focused history and perform a physical
examination, including a digital rectal examination.
b. The next step is to measure the level of PSA (prostate-specific antigen) which
is a marker of prostate cancer.
c. Perform other routine blood tests: LFTs for evidence of liver metastases; high
ALP and calcium levels may be indicative of bone metastases.
d. Perform a transrectal ultrasound and transrectal biopsy in order to get a tissue
diagnosis.
e. CT or MRI scan can be used to assess local and distal spread of disease
(tumour staging), as well as any bone lesions.
f. Refer for a combined urology/oncology multidisciplinary team opinion.
12. The Gleason score is a histological scoring system used to determine the grade
of differentiation of prostate cancer. This is based on the two most common
glandular patterns seen on prostate biopsy. Each of commonest patterns is scored
from 1 to 5.
The sum of the two gives an overall score out of 10. A score of 1 represents a
well-differentiated tumour (best outcomes), while 10 is a very poorly
differentiated one (worst outcomes).
13. In testicular tumour the initial diagnosis is a clinical one. Tumour markers may
161
be elevated: β human chorionic gonadotropin (90% in teratoma, 25%
seminoma), α-fetoprotein (50% in teratoma) and alkaline phosphatase (50% in
seminoma). CT identifies para-aortic or mediastinal lymph nodes or secondaries
in the liver or lungs. The treatment is orchidectomy via an inguinal approach.
The testis is delivered through the incision in the external oblique and a vascular
clamp is applied to the spermatic cord while a biopsy and frozen section are
taken to confirm the diagnosis. A high ligation of the cord and orchidectomy are
then undertaken. Subsequent management depends on the stage and the pathology.
Stage 1: rising tumour markers post-orchidectomy; stage 2: abdominal nodes;
stage 3: supradiaphragmatic nodes; and stage 4: lung or liver metastases.
162
Most of this book is devoted to specific systems or parts of the body. However, you
may be asked for a more general approach (as considered here), and similarly you
may be told to examine a limb, with no clues from the examiner as to which system
is abnormal. Always approach the problem by looking systematically and
remarking on any abnormalities that you see. Then go on to examine the appropriate
systems.
In the upper limb, this may focus on the hand (see here), or the joints of hand and
the rest of the limb. In the lower limb it may relate to the joints or the vascular
system, as considered in subsequent sections. The scheme on the following pages
gives an initial approach to examining a leg.
163
164
165
The most common orthopaedic long and short cases are hip and knee. However, do
not panic if you are given a shoulder, an elbow, an ankle or a back to examine.
Follow the same routine for all joints and with your chosen colleague (see here) go
through the routine of look, feel, move and measure, and tell the examiner you
would like a radiograph to confirm your findings. Never forget to expose both sides
of the body, and at the end to check pulses and peripheral sensation. (In a
rheumatological examination, you are expected to examine gait, arms, legs and
spine – GALS.) Your routine should include the joint above and below.

POPULAR VIVA QUESTIONS
1. Describe the clinical features of a patient with osteoarthritis (OA) of the
knee.
10. You have finished examining a painful knee. What would you like to do
next?
169
ANSWERS
1. The patient has an antalgic gait, with a varus deformity of the knee. On palpation
of the knee joint osteophytes are present. Passive movement of the knee reveals
crepitus. The quadriceps is wasted due to lack of activity secondary to pain.
6. Diagnosis of a red swollen joint requires a focused history with the above
differential in mind, followed by an examination. Perform simple blood tests to
looks for evidence of infection or inflammation (WBC, CRP, ESR) . Rheumatoid
factor and ANA levels are requested if the history is suggestive of non-infectious
inflammatory disease. Do a full set of X-rays to identify any evidence of
rheumatoid or osteoarthritic changes, as well as fractures.
Discuss joint aspiration with your Consultant, (for crystals and culture – see
170
question 8).
7. If the joint cannot be moved due to pain or swelling and the patient is tachycardic
or has a pyrexia, consider septic arthritis as a diagnosis (unlikely in an
examination, but an important aspect of the differential diagnosis). Also
determine source of sepsis (eg superificial trauma or infection/abscess at another
site causing haematogenous spread). Septic arthritis is an orthopaedic
emergency. Aspirate joint, sending fluid for Gram stain and culture, but get a
senior opinion first. For gout (urate crystals) or pseudogout (calcium
pyrophosphate crystals) analyse aspirated fluid under polarised light
microscopy.
b. To relieve pain and discomfort caused by swelling (although this may only be
temporary)
c. To aspirate pus and perform a joint washout (this requires more than just a
needle and syringe and so needs to be undertaken by orthopaedic surgeons in a
sterile environment).
Every time a joint capsule is breached the patient is exposed to the risk of septic
arthritis. Currently many hospitals strongly discourage joint aspiration by junior
doctors or performance of the procedure on the ward or in the Emergency
Department, where the risk of introducing infection is high (the consequences are
potentially disastrous after knee replacement).
This can be a trick question in the examination, so always state that you would
seek orthopaedic advice before considering aspirating a joint. Follow this
advice once you qualify.
9. Gout requires NSAID analgesia (eg diclofenac) in the short term (acute
episodes), followed by long-term allopurinol to reduce uric acid levels.
10. When finishing an examination say you would like to examine the joint above
and the joint below (hip and ankle) to ensure that the pain doesn’t radiate to the
knee from other joints. Ask to examine anterior and lateral X-rays of the affected
knee, as well as X-rays of the contralateral knee joint (in two planes).
171
172
THE HISTORY
Pain
Ask the usual questions about pain (see here). Be clear as to where your patient’s
pain is felt maximally and where it radiates. Ask specifically if there is any knee
pain. When enquiring into exacerbating factors, ask about actions that load the joint,
eg putting on socks, sitting in a low chair, rising from a sitting position and walking.
Question the character of the pain: throbbing pain – abscess (? systemic symptoms);
aching – arthritis; burning – neuralgia; stabbing – tendon or muscle rupture.
Stiffness
Ask if this is worse in the morning, on movement or after staying in one position.
Pain and swelling around the hip may indicate non-orthopaedic problems, such as a
hernia (see here).
Walking
• Ask in detail about aids and appliances: does the patient need a walking stick or
a Zimmer frame?
173
In a long case, you must take a detailed social history. Find out how the problem
affects the patient’s lifestyle and whether it is deteriorating. Ask about the
involvement of other joints: many patients with osteoarthritis or rheumatoid
arthritis of the hip will have had other joint replacements. You are unlikely to
encounter a child in finals, but remember presentation may be a limp or delayed
walking, as well as the above symptoms. Aetiological factors are considered in the
FAQs at the end of the chapter.
THE EXAMINATION
The examination of the hip and knee is where most candidates let themselves down.
You will probably not have had nearly as much practice as, say, in examining an
abdomen. Practise on each other: it is very easy for the examiner to see if you have
done it before.
Most of the patients in short cases will have osteoarthritis and will be fairly
fragile. If they are supine when you are introduced, it is probably simpler to start
examining in this position. However, never forget to stand the patient up to perform
the Trendelenburg test and to watch the gait – if they are sitting, start with these
manouvres.
In a long case, it is essential to examine the peripheral vascular system and to look
for signs of infection in the leg. Both ischaemia and infection could potentially
compromise a total hip replacement.
174
175
176
TYPICAL CASES
177
Case 1: hip pain
If you meet a patient with a hip disorder in the long case/OSLER, he or she will
almost certainly complain of pain.
You should know the characteristics of hip pain: this is usually felt maximally in the
anterior groin. However, it is poorly defined and radiates variably to the following
areas:
• Anterior thigh
• Lateral thigh
• Buttock
• Anterior knee
Remember that a patient with a primary hip disorder can present with isolated knee
pain. This is because both the hip and knee contribute fibres to the obturator and
femoral nerves.
Use the table opposite to differentiate hip pain from other local or distant causes.
Diagnosis: by clinical examination of the joints. Also assess for sensory and motor
loss suggesting nerve damage. Radiographs identify abnormalities of the spine,
pelvis and hip (important to compare the two sides), and are supplemented by
images that identify soft-tissue changes of the spine, pelvis and hip joint.
Treatment: this depends on identified cause of pain. Bursae can usually be treated
conservatively until the inflammation subsides. Arthritic pain is managed by non-
steroidal anti-inflammatory drugs, although preferably not long-term. The lateral
cutaneous nerve of the thigh should be released in meralgia paraesthetica. A
protruded disc and peripheral vascular stenotic problems may require surgical
management. Severe hip arthritis may require prosthetic hip replacement or hip
joint resurfacing. In all cases, consider physiotherapy, the use of a walking stick,
and weight reduction.
178
Case 2: abnormal gait
You may be asked to describe the gait of a patient with hip pathology.
The two main types are the antalgic (painful) gait and the Trendelenburg gait
(waddling gait if bilateral). You should know how they differ.
You may be asked to describe the mechanism of the Trendelenburg gait. This is
probably best understood by considering the Trendelenburg test. Normally, when
standing on one leg, the abductors on the weight-bearing side contract so that the
pelvis rises on the opposite side. A positive Trendelenburg test occurs when there
179
is any inefficiency of hip abduction: the pelvis droops towards the unsupported
side – the pelvis has to be raised for the swinging leg to clear the ground.
You may be asked the reasons why you measure apparent leg length and perform
Thomas’ test: arthritis may result in contractures that give rise to deformities, and
osteophytes inhibit movement. The most common are fixed adduction and flexion
deformities. Both can be masked by compensatory movements.
The aim of measuring apparent leg length and of performing Thomas’ test is to
180
unmask these contractures.
A fixed adduction deformity tends to cross the legs. Therefore the pelvis
compensates by tilting towards the affected side. This leads to apparent leg
shortening. (True shortening arises from loss of joint space or arthroplasty.)
b. Thomas’ test
A fixed flexion deformity can be completely masked when lying flat, by a lumbar
lordosis. This is unmasked by performing Thomas’ test.
At rest, both legs rest straight on the couch, the normal lumbar lordosis masks
any fixed hip flexion.
Normal – the right hip extension keeps the right leg straight and in contact with
the couch
Positive Thomas test: flexion of normal left hip reveals fixed flexion of the right
181
Use your right hand to flex the left leg and slide your left fingers under the back
to feel when it is flat – at this point the angle x gives the amount of fixed flexion.
182
POPULAR VIVA QUESTIONS
1. What are the risk factors for congenital dislocation of the hip?
3. How would you manage a baby presenting with congenital dislocation of the
hip?
10. What are the operations available for a patient with osteoarthritis of the
hip?
183
ANSWERS
1. Developmental dysplasia (congenital dislocation of the hip) occurs in up to
5/1000 live deliveries. It has a polygenic inheritance pattern and is associated
with high maternal relaxin and breech position of the baby. It is associated with
acetabular and proximal femoral dysplasia.
2. In neonates, screen with Ortolani’s test: abduction of the hips in 90° flexion is
impeded; pressure on greater trochanters reduces the hips with a clunk and
further movement is then possible. Barlow’s test attempts to lever the hips in and
out of the acetabulum during abduction. Late features are asymmetry, clicking and
difficulty in changing nappies.
184
Remodelling results in an abnormally shaped femoral head.
7. True shortening is due to joint or bony abnormality of the hip, knee or lower leg,
and is determined by comparing the distances from the greater trochanter to the
lateral malleolus on each side. Apparent shortening is seen when malalignment
between the ankles (on lying) is caused by pelvic tilting, as occurs in a fixed
adduction deformity. Measurement from the umbilicus or symphysis pubis
highlights the difference between the sides.
12. Young patients, particularly those still undertaking active contact sports because
any subsequent revision is accompanied by a much higher complication rate;
mild disease; severe degenerative disease with destruction of the hip joint or
multiple joint involvement; when there is doubt as to the origin of the hip pain
such as with coexistent scoliotic problems; patient refusal or mental apathy
towards the procedure; severe comorbidity; and obesity.
185
Grades I and II undisplaced can be managed with cannulated hip screws.
Displacement disrupts the blood supply of bone, reducing the chances of natural
healing and together with extra-capsular fractures are indication for radical
surgery, extending to total hip replacement.
186
THE HISTORY
If you have a patient with a knee complaint in the long case, bring out the following
aspects in your presentation.
Pain
• Tell the patient to point with one finger to where the pain is felt maximally.
Stiffness
Ask if this is worse in the morning, on movement or after staying in one position,
post-inactivity suggests arthritis.
Swelling
If preceded by an injury:
187
• Did the swelling occur after a few hours?
THE EXAMINATION
As with the hip, examination of the knee will probably be relatively unfamiliar:
practise on each other.
Don’t worry too much about the ‘additional assessment’, eg the apprehension test
and McMurray’s test. Most of your examiners are not orthopaedic surgeons and just
want to see that you have a basic routine of LOOK, GAIT, FEEL, MEASURE,
MOVE.
Never forget to ask to see the patient walk at the end of the examination. This will
also give you the opportunity of looking at the popliteal fossa for posterior knee
swellings.
188
189
190
191
TYPICAL CASES
As with the hip, pain is the most common presenting symptom. It may be associated
with stiffness and mechanical problems. The aetiology of knee pain in the aged is
usually arthritic, while the contact activities of young adults make them subject to
mechanic problems. There are also a large collection of other problems that give
knee pain, including paediatric conditions and referred pain – these are first
considered in Case 1. NB pain in the knee: always examine the hip.
1. KNEE PAIN
First ask yourself if the pain is due to knee pathology or if it is referred.
192
non-traumatic. Traumatic may be intra-capsular (producing a haemarthrosis
within an hour) or an extra-capsular injury. Non-traumatic conditions can
classified by their position, and as common, paediatric and uncommon.
b In children consider:
• Osgood –Slatter’s disease
• Growth spurt (especially adolescent girls)
• Chodromalacia patellae (especially adolescent boys)
• Osteochondritis dissecans
• Obesity
• Referred hip pain (NB an important differential)
Treatment:
193
• Soft tissue injuries to the collateral ligaments are immobilised with a high knee
brace followed by physiotherapy
• In cruciate ligament damage, as with hamstring conditions, physiotherapy and
rehabilitation can negate the need for surgical reconstruction
• Meniscal injuries inevitably require arthroscopy and partial meniscectomy, but
peripheral early tears may be sutured
• Patellofemoal disorders require biomechanical assessment and rigorous
quadriceps physiotherapy
• Trauma with tibial plateau fractures inevitably require open reduction and
fixation: with aspiration of the joint and elevation, progressing to cast brace for
early mobilisation. Traction may also be applied when osteoporosis is present.
Undisplaced patellar fractures can be managed with a backslab and mobilisation
but displaced fractures may require wiring followed by a cast brace.
• In tuberculous disease, a full drug course must be given. Subsequent management
may include that of osteoarthritic changes.
• Osteoarthritis and rheumatoid arthritis are treated as summarised in Case 2.
Case 2: arthritides
Compare and contrast the symptoms and signs of rheumatoid arthritis and
osteoarthritis.
Ask specifically about the pattern of stiffness: this may tell you about the joint
pathology.
194
If you are asked to examine the knee in a short case, always glance at the hands.
This will give you a clue if your patient has rheumatoid arthritis.
Remember: the knee may be the only joint involved in osteoarthritis; in rheumatoid
arthritis, it is usually involved as part of a generalised syndrome (for hands see
here).
Look carefully for scars of previous operations: your patient may have had a joint
replacement. Look also at the thigh: note that in all knee injuries there is rapid
muscle wasting of the thigh muscles, particularly of the medial quadriceps.
Treatment: osteoathritis of the knee is treated with analgesics and knee elastic
support, progressing to depomedrone intra-articular injection and washout of
degenerative material. If symptoms progress, other measures may include
patellectomy, tibial osteotomy, prosthetic joint replacement or arthrodesis.
Treatment of rheumatoid arthritis involves treating the generalised disease and, in
the knee, arthroscopic synovectomy. When symptoms are not controlled by drugs,
osteotomy is undertaken for marked valgus deformity and prosthetic joint
replacement for extensive joint destruction. In both diseases, haemarthrosis and
effusions are aspirated. Physiotherapy is an important aspect of rehabilitation.
True locking occurs with menisceal tears in plica syndrome (trapping of a synovial
fold) and loose bodies (‘joint mice’). Know the causes of joint mice:
• Osteochondritis dissecans
• Synovial chondromalacia
• Osteochondral fracture
195
• Localised separation of articular cartilage.
Treatment: when loose bodies or meniscal tears are present, arthroscopy allows
diagnosis and treatment of the underlying problem, removing loose bodies and any
damaged cartilage. If the anterior cruciate ligament requires replacement or repair
for tears or knee instability, followed by a hinged knee brace and 12 –18 months
rehabilition.
2. KNEE SWELLINGS
Most lumps in and around the knee are due to bursitis or diverticula. Know the
differential diagnosis.
a. Anterior (rare)
196
• Infrapatellar bursa (clergyman’s knee)
• Osgood-Schlatterdisease.
b. Lateral/medial (rare)
• Cystoflateralmeniscus
• Cystofmedialmeniscus
• Exostosis.
c. Posterior
• Semimembranous bursa
• Baker’s cyst
• Poplitealaneurysm.
• Smooth surface
• Fluctuant
• Transilluminable
• Immobile.
Here the swelling is over the patella. Ask the patient his or her occupation: it is
common in carpet layers, tilers and roofers, but not so common in housewives!
197
c. Osgood–Schlatter disease
Treatment: bursae and cysts are usually managed conservatively but may, if
infected, need aspiration and appropriate antibiotics.
The swelling is behind the knee in the medial part of the popliteal fossa, above the
joint line.
This is a synovial diverticulum extending into the popliteal fossa through a deficit
in the posterior capsule. The swelling is behind the knee, below the joint line. You
may be asked to distinguish the terms ‘popliteal cyst’ and ‘Baker’s cyst’:
Popliteal cyst:
• No underlying pathology
Baker’s cyst:
c. Popliteal aneurysm
• Palpate the abdomen and groin for associated aortic femoral aneurysms.
198
Treatment: bursae and cysts (see Case 5). Popliteal aneurysms require surgical
repair to prevent acute ischaemia from thrombosis or rupture.
a. Bone fractures:
c. Joint dislocation:
• In such cases also consider damage to the joints below, eg impacted fracture of
the neck of femur and ankle sprains. Remember: pain in knee – examine the
hip.

FAQS AND POPULAR VIVA QUESTIONS
1. What is the normal angle of the femur on the tibia?
10. Where is the most common site for a meniscus to tear? How would such an
injury present?
200
ANSWERS
1. The tibiofemoral angle is 5–7° of femoral valgus. It is usually greater in the
female due to the wider pelvis.
2. Genu varum (bow-legs):>6cm between the knees when the heels are together.
Physiological normal finding in babies; abnormal growth of the posteromedial
proximal tibial epiphysis; osteoarthritis and cartilage loss in the medial
compartment; Paget’s disease and epiphyseal injury; vitamin C and D deficiency.
4. Painful swelling of the tibial tubercle in adolescence due to traction injury of the
apophysis. Spontaneous recovery with alteration of activity.
7. Meniscal tear (including bucket handle); loose bodies (joint mice) such as in
osteochondritis dissecans; synovial chondromalacia; osteochondral fracture;
localised separation of articular cartilage and plica syndrome (trapping of a
synovial fold).
201
10. Splitting is usually along the length of the medial meniscus:bucket-handle tears
remain attached at each end. It presents with severe pain, usually on the medial
side of the knee, often as a sports injury. The knee is typically locked in flexion.
Swelling follows a few hours or days later. Recurrent and chronic problems may
requir surgery.
202
THE HISTORY
Hand and foot problems usually come up as short cases and OSCEs. You may be
told to ask the patient a few questions: first ask about the patient’s main complaint.
Then go through the usual questions about pain and swelling (here and here), and
autoimmune conditions.
THE EXAMINATION
The instruction will usually be to ‘examine this person’s hands’. Seek clues as to
the underlying cause right from the beginning.
203
• Elbows: ?rheumatoid nodules
204
205
206
If you are asked to examine a patient’s foot, follow the usual routine of ‘LOOK,
FEEL, MOVE, MEASURE’, examining each joint in turn as outlined here. There
will usually be an obvious abnormality which you should describe systematically
before giving your diagnosis.
TYPICAL CASES
1. THE HAND
207
The most common cause of a contracted hand is Dupuytren’s contracture:
• Feel for the hard, subcutaneous nodules on the palmar surface – usually involving
the 4th and 5th digits.
• Ask to examine the soles of the feet: similar nodules may be felt.
• Do you drink alcohol? How much per day? Do you have any liver problems?
208
involved) with splintage for 6–12 weeks postoperatively. In severe, persisting,
disabling deformity the little finger may have to be amputated.
Volkmann’s contracture and shortening of the intrinsic hand muscles are usually
managed conservatively although muscle release procedures and tendon transfers
may be possible.
• Trauma.
Note that the palm may be spared as the palmar branch of the median nerve passes
superficial to the flexor retinaculum.
Opponens pollicis
c. Positive Tinel’s sign and Phalen’s test (see examination scheme, here).
209
arise from repeated trauma to the heel of the hand, in which case there is no sensory
loss. Revise the signs:
c. Motor loss and wasting: affects the interossei; most noticeable dorsally. There
is weakened finger abduction and adduction.
The main signs are wrist drop and wasting of the posterior forearm muscles. There
is very little sensory loss – only over the anatomical snuffbox.
a. Position: arm internally rotated with the forearm pronated and the palm facing
backwards (the waiter’s tip sign).
210
This can be caused by a cervical rib or apical lung tumour (Pancoast’s tumour):
remember to check for an associated Horner syndrome – miosis, ptosis,
enophthalmos and anhidrosis of the face.
The hand is clawed and wasted. There is sensory loss over the inner aspect of the
arm and forearm.
Treatment: where the nerve injury is neuropraxia, there may be some spontaneous
recovery. For more severe injuries, the site of damage must be identified and
immediate repair may be possible. Recovery is more likely in children and in pure
motor or sensory nerves. Brachial plexus injuries involving avulsion of the nerve
roots are not amenable to surgery and a useless, flail, upper limb is an occasional
indication for amputation. Progress of healing can be followed by a positive Tinel’s
sign.
Cause: extensor tendon rupture (close to ulnar styloid and rheumatoid arthritis).
Treatment: surgical correction, by transferring the lateral slip of the tendon to the
middle phalanx.
• When patien straightens out hand, affected finger remains bent and then
straightens with a click
• Feel for a tender nodule over the tendon sheath, over the distal palmar crease.
Treatment: steroid injection; if fails, the stenotic area of the tendon sheath is
incised to release and allow free movement of the tendon.
212
Case 12: rheumatoid arthritis
This is a very common short case. You should be able to describe the characteristic
deformities:
• Boutonnière deformity
• Swan-neck deformity
• Dorsal subluxation of the ulna at the carpal joint (piano key sign).
213
• Squaring of thumb: involvement of carpometacarpal joint of thumb.
• Simple analgesia
• Test abductor pollicis brevis and the interossei for median and ulnar nerve
palsies respectively.
Fractures can occur in the carpal bones of the wrist, the radius or ulna, as well as
in more proximal joints such as the shoulder due to pressure transmission.
1. Colles’ fracture: fracture of the distal end of the radius bone, with shortening,
and dorsal diplacement and angulation of the fractured distal segment. This gives
the classic ‘dinner-fork’ deformity of the wrist and is typical of a fall on an
214
outstretched hand. The wrist can be ‘pulled’ (reduced) using local anaesthesia
(into haematoma or a biers block), sedation and analgesia; or it can be
manipulated under anaesthesia, followed by fixation in a plaster cast. Complex
fractures may require open reduction and internal fixation (ORIF). Persistent
deformity and poor wrist function are common complications of inadequate
reduction and immobilisation.
2. Smith’s fracture: fracture of the distal radius with volar angulation (opposite to
Colles’) of the fractured segment. This occurs when the impact occurs on the
dorsum of the hand.
3. Scaphoid fracture (more common at a younger age): the patient is tender over
the anatomical snuffbox (space between the extensor tendons of the thumb:
extensor policis longus vs extensor policis brevis and abductor policis longus).
The pain can be reproduced by a telescoping movement of the thumb (as if trying
to pull thumb out or push it in). Avascular necrosis of the proximal scaphoid
segment can occur due to disturbance of the blood supply to it. Treatment
normally involves immobilisation with a plaster from the upper forearm to just
proximal to the metacarpophalangeal joints of the fingers, but including the
metacarphphalyngeal joint of the thumb, with the wrist slightly extended (the
glass holding position), for 6-8 weeks.
1. Humeral shaft fractures may damage the brachial artery (anteriorly) and radial
nerve (posteriorly). Clinical and radiological diagnosis are needed. Radial
nerve damage presents with loss of wrist extension (motor) and loss of sensation
over first dorsal web space of the hand (sensory).
215
can be reduced using Kocher’s method. Recurrent dislocation of the joint can
occur.
4. Rotator cuff injuries: may involve any of the short articular muscles, causing
painful movements (rotar cuff; tendinitis). The supraspinatus may impinge on the
acromion producing a painful arc on abduction. Transection of supraspinatus may
be accompanied by an inability to initiate shoulder abduction. Treatment includes
repair of torn rotator tendons and removal of any bony irregularities on the
acromion.
2. THE FOOT
The three common foot problems you will see in an examination are hallux valgus,
hammer toe and claw toes.
216
This usually affects the second toe. It can be bilateral. There is a fixed flexion
deformity of the PIP joint.
• Rheumatoid arthritis

ANSWERS
1. Median: thenar muscles and lateral two lumbricals, flexor digitorum
superficialis and lateral two tendons of flexor digitorum profundus. Ulnar:
hypothenar muscles, adductor pollicis, tendons of flexor digitorum profundus to
ring and little finger. Radial: posterior compartment muscles (the long extensor
tendons are supplied by its posterior interosseous branch).
2. Median: thenar wasting, loss of thumb abduction, flexion of ulnar fingers but
pointing of the index finger, loss of wrist flexion and pronation. Loss of sensation
over the radial three and a half digits including the nail beds. Ulnar: loss of
intrinsic muscle function of the hand produces a claw hand with loss of finger
abduction and thumb adduction. Loss of sensation over the ulnar one and a half
digits including the nail bed. Positive Froment’s sign. Radial: loss of elbow
extension with injuries to the upper arm; loss of extensors of wrist, fingers and
thumb, and thumb abduction. Sensory loss over anatomical snuffbox.
3. Median: penetrating injuries in the arm and forearm, elbow dislocation, carpal
dislocation, carpal tunnel syndrome due to fluid retention in association with
congestive cardiac failure, pregnancy, connective tissue disease (rheumatoid
arthritis), endocrine disease (acromegaly, myxoedema).
Radial: falling asleep with the arm hanging over the back of a chair (Saturday
night palsy), midshaft fracture of the humerus with damage in the spiral groove,
penetrating injuries and fracture dislocation of the elbow.
Prolonged use of a tourniquet or acute ischaemia can damage all three nerves.
219
5. De Quervain’s tenosynovitis is thickening, inflammation and tenderness of the
tendon sheaths of extensor pollicis brevis and longus, and abductor pollicis
longus, giving pain on thumb abduction against resistance and passive adduction.
6. Patient’s finger clicks when it is bent and usually has to be forcibly straightened.
A palpable tendon nodule over the distal palmar crease, may be present.
Symptoms are due to trapping of the nodule by a stenosis in the sheath.
8. In club foot, the ankle is in equines, the heel inverted and the forefoot adducted
and supinated, so that the foot sole faces posteromedially. The foot cannot be
dorsiflexed to touch the leg as is normal in neonates.
9. Flat feet are common and no treatments are required in asymptomatic children
or adults. Treatment is indicated in tarsal conditions (fixed/fused tarsals) and
failure of correction of the medial arch when on tiptoe. Initially plaster with foot
in plantar grade position, if failure, surgical intervention.
10. In hallux valgus, there is excessive lateral angulation of the big toe away from
the axis of the metatarsal. It can be treated by appropriate footwear and, when
symptomatic (eg an infected bunion), the prominent part of the metatarsal head
can be excised with a corrective osteotomy. Alternative surgical treatments
include excision of the metatarsophalangeal joint or arthrodesis.
11. Hallux rigidus is stiffness of the first metatarsophalangeal joint. Causes include
osteoarthritis, trauma, osteochondritis or gout, usually without the associated
lateral angulation of the toe of hallux valgus.
12. Pes cavus is usually idiopathic but may be secondary to neurological disorders
such as peroneal muscular atrophy or Friedreich’s ataxia. It is often associated
with clawing of the toes and with callosities under the metatarsal heads. The
metatarsophalangeal joints are extended and the interphalangeal joints are flexed.
220
THE HISTORY
‘Arteriopath’ patients are readily available for examinations because of their age
and complications. They are usually given as long cases, because the histories tend
to be extensive. In your ‘history of presenting complaint’, include not only the
symptoms of peripheral vascular disease, but also all other symptoms, risk factors,
past history, and family history of cardiovascular and cerebrovascular and lower
limb arterial disease.
Presenting symptoms
• Can you describe the pain in your legs? (Ask pain questions, see here)
• How far can you walk before you get the pain? (Claudication distance is best
described in terms of a known distance, eg from the entrance of the hospital to
the clinic.)
• When you stop walking, how long does it take for the pain to go away?
• How long have you had the problem? Has it got any better or worse over this
time?
• How does it affect your lifestyle and does it interfere with your work?
221
• What relieves your pain? (Rest pain may be relieved by walking about and
hanging the leg over the side of the bed)..
• Where is the pain in your leg (calf, thigh, buttock)? In a man, ask about erectile
function (Leriche syndrome).
Risk factors
Ask about smoking/hypertension/diabetes/cholesterol levels.
Family history
Ask about a family history of cardiovascular/cerebrovascular/peripheral vascular
disease.
222
Tailor the rest of your history towards the differential diagnosis – it is important to
ask about neurological symptoms, such as paraesthesia in the leg, because there
may be a neurological cause of the pain.
THE EXAMINATION
The OSLER/long case
Pay particular attention to the following:
• Peripheral vascular system: look for ulcers on pressure areas and over the tips
and between the toes. Record all pulses and bruits on a diagram (see here); felt
against underlying bone – ?enlarged
• Heart
• Fundoscopy
223
224
225
226
TYPICAL CASES
It is extremely unlikely that you will have a patient with an acutely ischaemic limb
in the examination because this is a surgical emergency. However, be aware of the
causes of acute ischaemia and the symptoms and signs – remember the 6 Ps:
1. Pain
2. Paraesthesia
3. Paralysis
4. Pallor
5. Pulselessness
6. Perishingly cold.
It is quite possible that your patient has symptomless arterial disease with loss of
227
pulses, but is suffering from a different cause of leg pain. Know the features of
claudication pain:
• Cramp like
Sciatica
This can be difficult to distinguish because the pain is also worsened by exercise.
The pain is felt in the hip joint but can be referred to the knee. It varies from day to
day.
This occurs in young people after unaccustomed exercise. The pain is felt in the
anterior part of the lower leg.
This is the most difficult to distinguish. There are two pathologies. Both lead to
sciatic-like pain and to limited straight-leg raising after exercise:
228
• Disc pathology: partial compression of cauda equina by prolapsed disc
Try to relate your patient’s symptoms (site of pain) and signs (absence of pulses,
presence of bruits) to the anatomy. Early claudication – superficial femoral; thigh –
common femoral; external iliac/profunda origin – unilateral buttock; bilateral
buttock – aorta. A mental picture of the angiogram helps.
229
If aortoiliac symptoms are unilateral, occlusion is probably of the common iliac
artery. If symptoms are bilateral (rare), occlusion may be of the aorta. Think of the
tetrad of Leriche syndrome:
• Bilateral pain
• Aortoiliac bruit.
Your examiner will almost certainly ask how you would manage your patient. This
is influenced by your assessment of the severity of your patient’s claudication. Use
the following parameters:
• How is it affecting your patient’s lifestyle or work? (How far does he or she
need to walk?)
Treatment: if patient can actively enjoy life, leave well alone (90% managed
conservatively); if not, consider arteriography and percutaneous dilation (the more
proximal the disease the better the result).
230
Case 2: rest pain/critical ischaemia
The patient will usually be male, aged 60 +. A strong clue that he has rest pain is if
his knee is bent or if his leg is hanging over the bed. Both these positions ease the
pain. The following features differentiate rest pain from claudication:
• Skin pallor
You may be asked why the pain occurs particularly at rest. There are three reasons:
• Microscopic angiopathy
• Infection.
231
The following features distinguish the diabetic foot from the critically ischaemic
foot:
Measure the horizontal distance between your fingers: remember that, especially in
thin females, the abdominal aorta is easily palpable.
Can your hand get above it? If so, it is infrarenal (most common).
Is the aneurysm tender? This suggests that it may be about to rupture (a very
unlikely examination situation!).
Auscultate over the swelling: a loud bruit (in the absence of a similar bruit in the
heart) supports the diagnosis.
Check the femoral, popliteal and foot pulses. These are usually present, as patients
presenting with aneurysms rarely have peripheral vascular disease. However,
emboli from the aneurysm may cause distal occlusion. There may be an associated
popliteal aneurysm.
232
endovascular aneurysm repair) or open surgical techniques.
Case 5: amputation
Peripheral vascular disease is by far the most common cause of amputation in
elderly people. You might meet such a patient in the long case.
Take a detailed history of the immediate events leading up to the amputation but do
not get bogged down in the probably lengthy history of previous operations such as
bypasses and sympathectomies.
Your history should be geared largely towards the sociological implications of the
amputation. Ask about mobility: can the patient climb stairs? Is he or she likely to
be confined to a wheelchair? Assess the patient’s ability to wash, dress and self-
care in other ways. Ask also about occupational therapy, home help, aids and
appliances.
Determine whether the amputation is below knee/through knee/above knee and look
carefully at the wound site. Is it infected? Are there contractures of the hip and knee
joints?
233
FAQS AND POPULAR VIVA QUESTIONS
1. Why does critical ischaemia lead to rest pain?
10. What are the risk factors for peripheral vascular disease?
234
ANSWERS
1. The blood supply is insufficient to keep the tissues alive; ischaemic metabolites
and associated ulceration produce pain.
3. (a) The effect on lifestyle: how far they can and need to walk, interference with
work activities and social life; (b) response to preventive measures, eg stopping
smoking, reaching an optimal weight and regular exercise; and (c) the rate of
progress.
4. In diabetes, arterial disease occurs a decade earlier than in the rest of the
population and is complicated by microvascular disease, neuropathy of motor or
sensory and autonomic fibres, and increased susceptibility to infection.
8. The ABPI is the ratio of the ankle to the arm blood pressure – usually >1 because
the muscle bulk of the leg gives slightly higher readings. The value is reduced in
lower limb arterial disease with a further fall on exercise.
9. Leg disease commonly starts in the superficial femoral artery at the adductor
hiatus or its origin. Symptoms become prominent once disease is present at two
levels, such as with additional popliteal or aortoiliac stenosis.
235
236
THE HISTORY
Include the following questions.
Presenting complaint
• What is your main problem? (The patient may be bothered by the appearance,
aches and pains or something else.)
• Are you on your feet all day? Do your legs ache more towards the end of the day?
• How long have you had the problem? Have you seen anyone about it previously?
Was it treated then?
Predisposing causes
• Have you ever been pregnant? Did you have any problems with your legs then?
Did one leg swell up?
• Have you had any major injuries or operations? Did you have any problems with
your legs then? Did one leg swell up?
237
• Have your clothes become tighter lately?
THE EXAMINATION
Venous insufficiency is a common short case. Practise the tourniquet test. It may
look easy on paper but the only way it doesn’t end up an embarrassing fiasco in
front of your examiners is for it to be a well-worn routine. Be absolutely clear
about its significance. You may think that you understand it but, with exam nerves,
explaining it is another matter. If you are being examined by a vascular unit, ask for
a hand-held Doppler to test incompetence before performing the tourniquet test.
238
239
240
TYPICAL CASES
Although a patient with an acute deep vein thrombosis is unlikely to come up in an
examination, you should know about the presentation and differential diagnosis of
this common emergency.
Be absolutely clear as to what is meant by the terms ‘varicose veins’ and ‘venous
insufficiency’. Your patient may have one or both of these conditions.
241
Case 1: varicose veins
Your patient will usually have primary varicose veins, ie no known underlying
cause. There may be a positive family history. However, always seek a secondary
cause (see history and examination above).
You may be asked to define varicose veins: these are ‘dilated, tortuous, thin-
walled, superficial veins’.
A knowledge of the anatomy will help in your description of the distribution of the
varicosities. Note that the muscular wall usually prevents dilation of the main leg
veins: varicosities occur in the tributaries.
242
Treatment:
243
• Venous ulcers (see here).
Your examiner will want to know if you have a clear understanding of the
difference between superficial and deep venous insufficiency.
Case 3: AV malformations
Although AV malformations are rare, they are lifelong problems, often with good
physical signs, and they may therefore turn up as short cases.
244
• Pulsatility
245
FAQS AND POPULAR VIVA QUESTIONS
1. Describe the aetiology of varicose veins.
3. What are the indications for operating on a person with varicose veins?
246
ANSWERS
1. Varicose veins are superficial, thin-walled, elongated, tortuous, dilated veins.
They may be primary congenital in origin, when there is often a family history.
Both primary and secondary varicose veins are associated with valvular
incompetence of the superficial system. Secondary varicose veins are associated
with disease of the deep veins, eg previous deep vein thrombosis giving rise to
superficial venous hypertension. Varicose veins may also be associated with
arteriovenous malformations and fistulae.
6. Venous gangrene, pulmonary embolism and late sequelae of long- term venous
insufficiency.
247
248
Chronic neurological cases usually form part of medical finals, but the cranial
nerves can be damaged by trauma and surgery, and sensory loss, and muscle
wasting and weakness are easily missed if not routinely checked in every limb
examination. This section considers surgically-related pathology.
249
250
Examination of the peripheral nervous system
Examination of the peripheral nervous system is not usually part of surgical finals,
but it is repeatedly emphasised that, in every limb (and major joint) examination,
you should check peripheral sensation (and pulses) and note muscle wasting. The
following scheme is for sensory testing of the upper limb. Upper limb nerve
injuries are considered with the hand (see here) and lower limb neurological
testing with examination of the limb (see here). Upper limb sensory testing (with
eyes closed) of dermatomes (individual nerves, see here).

POPULAR VIVA
QUESTIONS
1. What is the Glasgow coma scale (GCS)?
8. What brachial plexus injuries would you expect from a motorcycle accident?
254
ANSWERS
1. The Glasgow coma scale is a system for assessing cerebral damage following a
head injury – it scores eye, verbal and motor performance, E + V + M: minimum
= 3, maximum = 15
255
3. Leaking cerebrospinal fluid is distinguished from other clear nasal drips by its
sugar content and, when mixed with blood, by a separate diffusion ring on filter
paper.
4. A bulbar palsy is produced by damage to the cranial nerve motor nuclei in the
brainstem (mid- and hindbrain). However, these nuclei receive a bilateral
cortical innervation; thus unilateral cortical lesions (lesions of the upper motor
neurone) produce no cranial nerve paresis (for an exception, see answer 6
below). Thus, to produce paralysis, cortical lesions have to be bilateral – when
this occurs it is referred to as a pseudobulbar palsy.
6. A lesion of the facial nerve nucleus in the pons or the nerve itself (ie a lower
motor neurone lesion) produces complete facial paralysis. The usual surgical
causes are parotid tumours, their surgical management and Bell’s disease. Only
part of the nucleus is bilaterally innervated (see answer 4 above) and in a stroke
patient, the lower face is paralysed but the upper face is spared.
7. The hypoglossal nerve innervates the tongue and damage to the nerve produces
wasting and weakness; on protrusion the tongue is deviated towards the affected
side. The nerve may be damaged by infiltrating malignancies of the pharynx and
surgery in the region of the carotid bifurcation. Unilateral cortical lesions do not
affect tongue movements.
8. The classic motorcycle injury of the brachial plexus is avulsion of the upper
(C5,6) roots (the helmet is in contact with the road and the shoulder is pulled
downwards, stretching that side of the neck). There is loss of elbow flexion and
supination. The limb hangs down the side, with palm facing backwards (waiter’s
tip position). This Erb’s palsy may also be encountered after a difficult forceps
delivery at birth.
256
10. Damage to the femoral nerve paralyses hip flexion and knee extension, and
produces numbness over the anterior and medial thigh and along the saphenous
distribution to the medial leg and foot. The injury can be caused by surgery
around the psoas muscle and sheath; a profound temporary paresis can follow a
spontaneous retroperitoneal bleed in patients on anticoagulants.
257
Surgical wards have a high proportion of postoperative patients who are readily
available for examinations. Patients who have recently undergone vascular,
gastrointestinal or transplant surgery may come up as long cases.
THE HISTORY
Take a history of both the presenting complaint (ie circumstances that led up to this
admission) and postoperative events. Screen for common postoperative
complications by asking the following questions.
Pain
• Are you in any pain? (Ask specifically about leg pain, chest pain and increasing
wound pain).
Respiratory symptoms
258
Gastrointestinal symptoms
Urinary symptoms
Ask also about drugs, including analgesics, antibiotics and heparin prophylaxis.
Take a detailed social history: Does the patient live alone? Who will look after
him or her after leaving hospital? On which floor does the patient live: are there
many stairs to climb/do the lifts work?
THE EXAMINATION
When you examine a postoperative patient, first take a note of the tubes and
measuring devices around the bed. Then go on to examine the patient. Finally, never
omit to look at observation, fluid and drug charts that will probably be available.

2. How would you determine the amount of fluid to prescribe in the first 24
hours after a laparotomy?
6. Define oliguria.
7. How would you manage a patient with oliguria for more than 24 hours
postoperatively?
8. How would you manage a patient with an increased pulse rate and drop in
blood pressure postoperatively?
10. What are the possible causes of a pyrexia between 2 and 10 days after

11. What are some of the alternatives for pain relief after surgery?
12. What are some of the predisposing factors for wound infection?
14. How would you manage a patient with (a) type 1 and (b) type 2 diabetes
pre-, peri- and postoperatively?
263
264
ANSWERS
1. Normal requirements: 2.5-3 litres a day of water; 70 mmol of sodium (1-2
mmol/kg) and 60 mmol of potassium (1 mmol/kg).
2. Fluid loss (through aspiration via a nasogastric tube, diarrhoea, stoma output,
vomiting, an intestinal fistula and sequestration of fluid requirement. However,
precise measurement of urine output (a catheter being routinely used after major
surgery) is documented on fluid balance charts, and also measured losses from
other sites. These measurements are supplemented by clinical examination and
other tests as described in the answer to question 3.
4. The previous two answers have considered replacing appropriate volume and
fluid loss. Attention is also given to the type of fluids prescribed. A typical
prescription is 2 litres of 5% dextrose to every litre of dextrose/saline to satisfy
daily requirements of sodium and carbohydrate. If the fluid loss is through
haemorrhage, this may be replaced by blood transfusion. Attention may also be
required to maintaining the circulating osmotic pressure of serum by prescribing
a colloid solution, such as Haemaccel or human albumin. Colloid solutions are
less likely than crystalloids to be rapidly excreted by the kidney. The logic of
replacing circulating fluid loss with a similar constituent such as human albumin
has not been consistently successful.
265
(after transfusing the wrong blood) with ABO and rhesus incompatibility,
urticarial and anaphylactic reactions. Other immunological complications
include transfusion-related acute lung injury and delayed reactions such as post-
transfusion purpura, graft-versus-host disease and immunomodulatory effects.
Non-immunological effects include hypothermia, hyperkalaemia,
hypercalcaemia, congestive cardiac failure and iron overload. Infection can
result from bacterial contamination of the transfusion apparatus or transfer from
the donor (eg hepatitis B and C, HIV-I and -II, HTLV-I and -II (human T-
lymphocytic virus), parvovirus, cytomegalovirus, malaria, babesiosis,
brucellosis, trypanosomiasis and syphilis).
266
devices and subcutaneous low molecular weight heparin.
13. The most common respiratory complication is infection. Dry gases and
reduced ciliary movement produce debris and, together with oropharyngeal
secretions, this predisposes to tracheobronchitis, pneumonia and acute
respiratory distress syndrome. Atelectasis is also common because ventilation is
not uniform throughout the pulmonary tree under anaesthesia, and the debris
causing infection may also block bronchi and bronchioles. Reduced
postoperative ventilation may be due to diaphragmatic splinting or sedation, and
is increased in those who smoke and patients with previous respiratory
problems; pain also inhibits respiratory executions. Pneuomothorax may be due
to hyperinflation and misplaced central lines. Pulmonary embolism may follow a
DVT.
14. People with diabetes undergoing major surgery should be brought into hospital
at least the night before surgery. Type 1 patients should be converted to short-
267
acting insulin. In type 2, oral medication should be changed to a short-acting
sulphonylureas. On the day of the surgery, an insulin-glucose infusion should be
started. The concentrations will depend on the patient’s expected requirement but
typically 15 U in a 500-ml pack of 5% dextrose can deliver 3 U in 100-ml
aliquots delivered over an hour. Concentrations are varied with hourly blood
sugar estimations and potassium supplements can be added to the infusion.
