The interruption of arterial blood flow in the superior segment of the femoral epiphysis is a common event in pathological conditions, e.g., gas embolism in Caisson disease, traumatic vessel injuries in neck femoral fractures or hip dislocation, vascular occlusion in Gaucher’s disease, sickle cell anemia, and radiation exposure. When arterial blood impairment occurs without a documented etiology, the term idiopathic avascular necrosis must be employed.
