Avascular Necrosis Prevention
Avoiding injuries, such as fracture of bone and dislocation of joints, will eliminate the risk of trauma-associated avascular necrosis. The key to the prevention of joint destruction from avascular necrosis is early diagnosis of the underlying cause. Optimal treatment of underlying diseases or conditions can reduce the risk of developing avascular necrosis.
Avascular Necrosis Prognosis
The underlying cause as well as the amount and location of bone affected by avascular necrosis to some degree determine the outcome. Larger areas of avascular necrosis often cannot be repaired by joint-preserving methods and ultimately joint replacement is necessary.
When an underlying disease or condition is the cause, optimal treatment of that disease or condition can decrease the chances of worsening the avascular necrosis or involvement of other areas of bone.
