What is the prognosis of aseptic necrosis?

Aseptic necrosis causes a serious injury to affected bone. Frequently, this leads to permanent destruction of the adjacent joint. Early core decompression is generally necessary to prevent collapse of affected bone. Aseptic necrosis can be complicated by complete loss of joint function.

Is it possible to prevent aseptic necrosis?

People can prevent aseptic necrosis by minimizing the use of steroid medications when possible and by treating underlying medical conditions, such as those described above, that can increase the risk of developing aseptic necrosis. Avoiding trauma to joints can prevent posttraumatic aseptic necrosis. Avoiding smoking can decrease risk of developing aseptic necrosis.
