Bilateral Osteonecrosis of the Femoral and Humeral Heads after Short Term Corticosteroid Therapy. A Case Study.

Steroid induced osteonecrosis is a devastating injury that usually requires rebuild of the joint, with the femoral and the humeral head being most commonly affected. Steroid therapy is the most common reported cause of atraumatic osteonecrosis. The Collaborative Osteonecrosis Group Study confirmed that steroids are the primary cause of multi-focal osteonecrosis in 91% of the cases.
