Conservative treatment of sickle cell avascular necrosis of the femoral head.
Treatment of avascular necrosis of the femoral head in adolescents with sickle cell anemia has not yet been standardized. In this study we review the literature and report on three patients with the Legg-Perthes-type avascular necrosis associated with sickle cell disease. These patients were successfully treated by partial weight-bearing with crutches and active range-of-motion exercises. We have examined physiologic and anatomic factors in this specific disease syndrome, which suggest that this may be the preferred method of treatment.
