Avascular Necrosis

Avascular Necrosis
  • Avascular necrosis is a condition which appears
    when there is a loss of blood supply to the bone,
    resulting in bone death. Avascular necrosis is
    also known as aseptic necrosis, ischemic bone
    necrosis, or osteonecrosis. Avascular necrosis is
    most common in the shoulder and hip but can
    affect other joints, such as knee, wrist, ankle,
    and elbow. If avascular necrosis is left
    untreated, it can result in severe arthritis and
    collapsing of bone. 

3
Causes of avascular necrosis
  • The most common cause of avascular necrosis is
    loss of blood supply to the bone tissue. Alive
    tissue needs the proper flow of blood supply in
    the joint. When blood does not reach the tissue
    it dies. There are a number of factors such as a
    disease, injury, or trauma. Sometimes a fracture
    or dislocation can affect the blood supply to the
    bone. Some other causes of avascular necrosis
    are
  • Blood clotting
  • Sickle cell disease
  • Anaemia
  • Excessive use of steroids
  • Excessive alcohol consumption
  • Radiation therapy
  • Uncontrolled diabetes
  • Leukaemia
  • Frequent inflammation in joints

4
Symptoms
  • In initial stages, there are no symptoms of
    avascular necrosis, as the disease progresses a
    patient may experience painful symptoms. Symptoms
    of avascular necrosis are 
  • Constant pain in the affected bone
  • Lack of movement
  • Groin pain, if hip bone is affected
  • Pain while walking or doing any other mild
    physical work
  • Weakness
  • Bruising of skin around the affected joint
  • Excessive swelling
  • Inflammation

5
Diagnosis of avascular necrosis
  • The doctor will begin the diagnosis with a
    physical examination of the affected joint and
    will ask questions such as, when did the patient
    first experienced symptoms. A doctor will also
    check your all-medical history to find out if
    avascular necrosis is related to any other
    disease present in the body. Diagnostic
    tests done to determine avascular necrosis are
  • X-ray- Reveals the changes in the bone structure
    if any.
  • Bone scan- A little amount of radioactive
    material is injected into your vein. The
    radioactive material makes the injured or healed
    portion visible on the imaging plate.
  • Magnetic Resource Imaging (MRI) and CT scan- Show
    the detailed images of which shows the change in
    the bone.

6
Treatments
  • The treatment of avascular necrosis depends upon
    its cause. The goal of the treatment is to revive
    blood flow and to prevent further bone
    damage. Medication
  • Cholesterol control medicine to reduce the
    excessive amount of bad cholesterol and fat in
    the patients blood. Excessive cholesterol
    hinders the proper flow of blood in the body.
  • Inflammatory drugs to provide relief from the
    inflammation and pain due to avascular necrosis.
  • Blood thinners and osteoporosis drugs to prevent
    blood clots and slow the progression of avascular
    necrosis.

7
Treatments
Continue
  • Surgical procedures 
  • Joint replacement- A joint replacement surgery is
    done to replace the damaged parts of joint with
    metal or plastic.
  • Bone transplant- The part of healthy bone removed
    and grafted with the affected bone this procedure
    is known as a bone transplant.
