Avascular necrosis of the femur head

A case of avascular necrosis of the femur head is presented. Its clinical picture is similar to that of osteoarthritis of the hip. The examination should include plain film radiography and radionuclide scan. When these two imaging procedures are equivocal, then magnetic resonance imaging should be considered. The therapy is often core decompression or total hip replacement, while conservative care is rarely indicated.
