Brief overview of the episode:

Avascular Necrosis is bone death due to poor or loss of blood supply. This most commonly affects the ends of long bones, femur, humerus and sometimes the carpal, metacarpal and tarsal bones.

Symptoms during the early stages are usual not noticeable. As the disease progresses pain, weakness and ROM loss are the most common signs. An x-ray is the clearest way to make a diagnosis.

In most cases trauma is the initial cause of avascular necrosis. There is also consistent evidence that long term cortico-steriod use is a risk factor.

Treatment is most often immobilization, with varying degrees of benefit. In most cases a joint replacement will be the final result.
