To review, osteonecrosis or “death of bone” occurs when the blood supply is disrupted to a joint. The most common cause of osteonecrosis is signficant trauma to the joint usually after certain types of fractures of the joint. Less frequently, certain medical conditions are associated with osteonecrosis such as sickle cell disease, lupus, high dose prednisone use, alcohol use, raynaud’s disease, vasculitis, hypercoaguable states. I think it might be difficult to prove your case but you should consider having an orthopedist review your case.
