BACKGROUND
Bone has many functions; including supporting the body tissue and
body organ shield, allowing the movement and mineral salt storage. Its
function, however, can be lost by fall, collision or accident that resulted in
fracture. A bone fracture is an event of continuity loss of bone tissue and/or
cartilage, which commonly caused by involuntary rupture. The injury that
causes fractures can be either direct or indirect trauma. 10
Fracture can be classified into open and closed fracture. In closed
fracture, there is no communication between bone fragments with the
environment. In open fracture, there is a communication between bone
fragments with the environment due to injury of the skin. The configuration
of fracture fragment including transverse, oblique, spiral, compression or
crush, comminuted and greenstick. 6
Fractures are more common in men than women under 45 years of age
and often associated with sports, work or injuries caused by motor vehicles.
Higher rate of mobilization in men is responsible for the high risk of
fracture. Whereas in older people, women are more likely to experience
fractures than men. It is associated with an increased in incidence of
hormone-related osteoporosis in menopause (Apley, 1995). Fracture of
intertrochanteric is one of 3 types of pelvic fractures. Intertrochanteric
fractures occur between 2 trochanters in which the greater trochanter is
attached by gluteus medius and minimus (hip extension and abduction) and
lesser trochanter is attached by iliopsoas (hip flexion) muscle. 3
The goal of rehabilitation is to return the patient function as high as
level of function prior the injury. In many cases, this is not realistic. Only
20% to 35% of patients can return according to the level of function before
the injury occurs. Approximately 15-40% of cases require constitutional
treatment more than 1 year after injury. About 50-83% of cases need tools to
help the ambulation. The aim of rehabilitation should be individualized,
with the therapist calculating comorbidity, fracture severity, and motivation
level of the patient. Successful in therapeutic goals of injuries or lesions in
the lower extremities are restoring the range of motion of all joints,
rehabilitation of all muscle and tendon units, and unrestricted weight
bearing.2,9
B. ANATOMY OF FEMUR
Femur, the longest and heaviest bone in the body, continues the
weight from os coxae to the tibia as we stand. The head of femur propagates
toward the craniomedial and slightly to the ventral when jointed with the
acetabulum. The proximal end of the femur consists of a femoral head and 2
trochanters (greater trochanter and lesser trochanter).8
C. DEFINITION OF FRACTURE
Fracture is defined as a break in continuity of the bone, often followed
by soft tissue damage with varying degrees, which affects blood vessels,
muscles, and nerves.3
The definition of intertrochanteric fracture of the femur is the break of
bone continuity in the area between the greater and lesser trochanter
extracapsullary.1
D. CLASSIFICATION OF FEMUR FRACTURE
The are two types of femur fractures:
1. Intracapsular fracture
Occurs in joint, hip, and capsule
Through the femoral head
Just below the femoral head
Through the neck of femur
2. Extracapsular fracture
Occurs outside the joints and capsules, through the greater or lesser
trochanter of the femur or in the intertrochanteric region.
Occurs distal to the neck of the femur but no more than 2 inches
below the lesser trochanter7
Intertrochanteric fracture
E. ETIOLOGY OF FRACTURE
1. Injury
Most fractures are caused by sudden and excessive muscle force,
due to beating, destruction, bending, twisting, or pulling force. When
exposed to direct force, the bone may be broken at the affected site; Soft
tissue is also undoubtedly damaged. When exposed to indirect forces, the
bone may fracture away from the affected site; Soft tissue damage at the
site of fracture may not exist.1
2. Compression
Cracks can occur in bone, just as in metals and other objects, due
to repeated pressures. This condition is most commonly found in tibia or
fibula or metatarsal, especially in athletes, dancers, and military
personnel who have gruelling exercise programmes 1
3. Pathological Fracture
Fractures may occur even with normal pressure if the bone has
been weakened (eg. by a tumor) or if the bone is very fragile (eg. in
Paget's disease).
F. DIAGNOSIS
To establish the diagnosis of fractures, history taking, physical
examination, and additional investigation are required, as follows:
1. History Taking
In general, there is a history of injury (mechanism of injury),
followed by the inability to use an injured limb. After falling down,
patient unable to stand, the affected leg is shorter and rotated compared
to the neck fracture of femur (because the fracture is extracapsular) and
the patient is unable to lift his leg.1
2. Physical examinaton
Localized sign in fracture may be found as follows:
- Look
Swelling, bruising, deformity may be obvious, but the important
thing is whether the skin is intact or not.1
- Feel
There is local tenderness, but it is also necessary to check the distal
part of the fracture to feel the pulse and test the sensation 1
- Movement
Crepitations and abnormalities can be found, but it is more important
to ask patient to move the joints in the distal part of the injury.1
3. Additional Investigation
Radiological examination of the hip joint including x-ray of pelvic
in anteroposterior (AP) view and injured areas, as well as lateral view of
hip. In some cases, CT scan may be required..4
G. FRACTURE HEALING
The healing process of the fracture begins since the fracture occurs as a
body effort to repair the damage. The healing of the fracture is affected by
several local and systemic factors, as for local factors:
1. Fracture site
2. Type of the affected bone
3. Stability of anatomical repositioning and immobilization
4. The presence of contacts between fragments
5. The presence or absence of infection
6. Severity of fracture
Systemic factors:
1. General condition of the patient
2. Age
3. Malnutrition
4. Systemic disease
v. Stage of Remodelling.
The fracture has been connected with a strong bone sheath
which is different from the normal bone. Within months and even
years there is a continuous process of formation and absorption of
bone, thick lamella will be formed at the side with high pressure. 1,3,7
