WebThe ball is the femoral head, which is the upper end of the femur (thighbone). The bone surfaces of the ball and socket are covered with articular cartilage, a smooth, slippery substance that protects and cushions the bones and enables them to move easily. The surface of the joint is covered by a thin lining called the synovium. Webform-shaped subchondral lesions possessing sclerotic margins of0.5-2 mm. Geodes were uniformly noted in areasofmaximal articular space loss,particularly along thesuperior middle andouter thirds ofthefemoral head. Rarely, smaller geodes were noted ontheinner andmiddle thirds ofthefemoral head, again inareas ofmaximum articular space loss.
WebAvascular necrosis is a disease resulting from the temporary or permanent loss of the blood supply to the bones. Without blood, the bone tissue dies and causes the bone to collapse. If the process involves the bones near a joint, it often leads to collapse of the joint surface.
