Treatment of atraumatic osteonecrosis of the femoral head is presently based not on disease prevention, but instead on the end-stage changes of bone associated with the necrotic lesion. Current diagnostic modalities are limited, by both cost and efficacy, in their ability to diagnose early-stage osteonecrosis. While many studies have assumed the cause of osteonecrosis is vascular occlusion, recent work suggests that alternate processes are primarily involved in the pathogenesis. By examining these concepts, a better understanding of osteonecrosis of the femoral head may lead to earlier diagnostic modalities and treatment protocols to prevent this devastating process from developing.
