    Bone Healing

    Uploaded by

    Haziq Mars
    The document summarizes the process of bone healing after a fracture, including potential complications. It describes the typical stages of fracture healing: (1) hematoma formation, (2) fibrocartilaginous callus, and (3) bony callus formation. Bone remodeling then occurs. Potential complications are classified as initial, early, or late stage and can be local or remote. Abnormal healing may result in malunion, delayed union, or non-union. Factors like age and location influence healing time. Both clinical and radiographic exams are used to assess the healing progress.

    Bone Healing &

    Complications
    Henry Sangapta Christian Munthe

    Bone Healing
    1. Fracture
    hematoma
    blood from broken
    vessels forms a clot.
    6-8 hours after
    injury
    swelling and
    inflammation to
    dead bone cells at
    fracture site

    2. Fibrocartilaginous
    callus
    (lasts about 3 weeks)
    new capillaries
    organise fracture
    hematoma into
    granulation tissue procallus
    Fibroblasts and
    osteogenic cells
    invade procallus.
    Make collagen fibres
    which connect ends
    together
    Chondroblasts begin
    to produce
    fibrocatilage

    3. Bony callus
    (after 3 weeks
    and lasts about
    3-4 months)
    osteoblasts
    make woven
    bone.

    4. Bone Remodeling
    Osteoclasts
    remodel woven
    bone into
    compact bone
    and trabecular
    bone
    Often no
    trace of
    fracture line on
    X-rays.

    Healing Time of a Fracture


    The healing time of fractures is
    extremely varied, but possible
    considering the following important
    factors: age, site and configuration,
    initial displacement, blood supply to
    the fracture fragments

    Assessment of fracture healing


    in patients
    The state of union of a fracture assessed
    by both clinical and radiographic
    examination
    The clinical examination consists of
    applying bending, twisting, and
    compression forces to the fracture
    Compression forces done to determine
    the presence or absence of movement
    Radiographic examination reveals
    evidence of bony callus.

    Abnormal Healing of
    Fractures
    The healing of a given fracture may
    be abnormal in one of three ways:
    Malunion
    Delayed union
    Non union

    Complications of Fractures
    Classification of the complications:
    Initial complications
    Early complications
    Late complications

    Complications of Fractures
    Initial (immediate) complications
    Local complications

    Skin Injuries
    Vascular Injuries
    Neurological Injuries
    Visceral Injuries

    Remote complications
    Multiple injuries
    Hemorrhagic shock

    Complications of Fractures
    Early Complications
    Local complications
    Sequelae of immediate complications
    Joint complications
    Bony complications

    Remote complications

    Fat embolism
    Pulmonary embolism
    Pneumonia
    Tetanus
    Delirium tremens

    Osteomyelitis
    Volkmanns Ischemic

    Septic Arthritis

    Complications of Fractures
    Late Complications
    Local Complications

    Joint Complications
    Bony Complications
    Muscular Complications
    Neurological Complications

    Remote Complications
    Renal Calculi
    Accident Necrosis

    General Principles of Fracture


    Treatment
    First, Do no harm
    Base Treatment on an Accurate
    Diagnosis and Prognosis
    Select treatment with specific aims
    Cooperate with the Laws of Nature
    Make treatment realistic and practical
    Select treatment for your patient as
    an individual

    Preliminary Care for Patients


    with Fractures

    Immediate care outside a hospital


    Airway
    Breathing
    Circulation
    Shock
    Fractures and dislocations
    Transportation
    Emergency Care in a hospital

    Specific Methods of Definitive


    Fracture Treatment
    Four basic goals of all fracture
    treatment:
    to relieve pain
    to obtain and maintain satisfactory
    position of the fracture fragments
    to allow, and if necessary encourage,
    bony union
    to restore optimum function
