The patient is a male of 52 year old and holds managerial position. He suddenly devloped left leg pain and low back pain seven years ago, which were followed by similar pain on his right leg and visited this hospital one year later. On X-ray examination, his right femoral head showed an image of spotty sclerosis and his left femoral head showed a punched-out image of sclerosis and spurs in its inside. As time went by, his symptoms were aggravated, and deformities of femoral heads and bone sclerosis progressed. However, owing to conservative treatment, his clinical symptoms have been alleviated and he walks quite normally now, but with a moderate limitation on internal rotation of hip joints. On X-ray, defor mities of both femoral heads are moderate, but bone sclerosis appears to have become less conspicuous and to be remedied. It would be necessary to follow up this case for an extended period of time.
