What can I do to prevent or lessen the chance of avascular necrosis?

What can I do to prevent or lessen the chance of avascular necrosis?

Options limited: Depends on the location and manner of fracture. Shoulder & hips at highest risk for avascular bone necrosis, so only real prevention is not getting injured to begin with. In some special cases you can take steps to reduce risk. Deep sea divers (due to the bends) and patients on high dose long term corticosteroids are more at risk. Talk to your dr. ...Read more

Non union fracture of two years at distal pole of scaphoid which recieves 100 blood supply.What are the chances of avascular necrosis setting in?

The waist of the scaphoid is the most risky for avascular necrosis as it does not have good blood supply. If you are having pain, surgery to remove the non-union is possible. If no pain, recommend leaving it alone. ...Read more

What should I do about avascular necrosis?

What should I do about avascular necrosis?

AVN: More information needed. In some bones (humeral + femoral head) if diagnosed before collapse and arthritis begins, there may be some value to core decompression. Some centers have shown decreased progression of collapse with free vascular fibula grafting (hip). No consensus regarding treatment before collapse. Once collapse occurs, some sort of resurfacing/replacement required to manage pain. ...Read more
