Clinically Relevant Anatomy

This disease involves the femoral head.

Mechanism of Injury / Pathological Process

The origin of this disease is unknown. The pathology of the disease is, however, accepted and is as follows.
First, there is interrupted blood supply to the capital femoral epiphysis. After this, an infarction of the subchondral bone occurs. Next, revascularization of the area occurs and new bone ossification begins. This is the turning point where a percentage of patients will have normal bone growth and development; while others will develop Legg Calve Perthes Disease. (LCPD). This disease is present when a subchondral fracture occurs. Usually, there is no trauma to cause this scenario. LCPD is most commonly the result of normal physical activity. Because of the subchondral fracture, changes occur to the epiphyseal growth plate.
