Bilateral femur head necrosis following high dosage corticosteroid therapy for chorioretinitis

摘要: The early development of bilateral osteonecrosis the femoral head after high doses steroids in two young patients suffering from chorioretinitis is described. Steroids were given orally and by parabulbar injections. Consecutive avascular necrosis was treated both cases flexion osteotomy combined with cancellous bone grafting lesion. In one case a pedunculate graft inserted. Early treatment requires diagnosis index suspicion affected patient, seems crucial respect to prognosis. Conventional X-rays hips, skeletal scintigraphy stage, appear be simple useful diagnostic tools.
