Avascular Necrosis Specialist Singapore
Avascular necrosis (AVN) is a condition that occurs when bone tissue dies because of too little blood supply. With avascular necrosis, the bone eventually collapses after tiny breaks occur. In most cases, the condition affects the thighbone (femur) in the hip area, but it can affect other bones in the body. These areas include the wrist, knee, and shoulder. Avascular necrosis gets worse with time. The condition is also called osteonecrosis, aseptic necrosis, or ischemic bone necrosis.
What causes Avascular Necrosis?
Avascular necrosis occurs when blood flow to a bone is interrupted or reduced, which may be caused by:
- Injuries to the bone, including a broken bone or dislocated joint
- Excessive alcohol intake
- Long-term use of steroids
- Decompression disease (the bends)
- Other medical conditions, diabetes, sickle cell anemia, kidney disease, gout, and Gaucher’s disease (a hereditary disorder that causes many problems , including erosion of the outer layer of the long bones and pelvis).
What symptoms of Avascular Necrosis?
- Pain and reduced range of motion in the affected joint
- Groin pain that spreads down the thigh to the knee
How is Avascular Necrosis diagnosed?
- X-rays. In the early stages of avascular necrosis, X-rays usually appear normal. But X-rays can often reveal bone changes that occur in later stages of the disease.
- Magnetic resonance imaging (MRI). MRI scans can show early changes in the bone that may indicate avascular necrosis. MRI uses radio waves and a strong magnetic field to produce detailed images of internal structures.
Avascular Necrosis Specialist Singapore Treatment for Avascular Necrosis (AVN)
Avascular Necrosis Specialist Singapore Treatment for Avascular Necrosis (AVN):
The treatment goal for avascular necrosis is to prevent further bone loss. What treatment you receive depends on the amount of bone damage you already have. Early stages of avascular necrosis may benefit from more conservative treatment, while later stages may require surgery.
- Total Hip Replacement (THR): If your diseased bone has already collapsed or other treatment options aren’t helping, you may need joint replacement surgery. Joint replacement surgery replaces your joint with an artificial one. It requires months of recovery, including time spent learning to use your new joint.
