Avascular Necrosis of Femoral Head in Dogs

Avascular necrosis (AVN) of the femoral head, also known as Legg-Calvé- Perthes disease (LCPD), is a debilitating orthopedic condition primarily affecting young, small to toy breed dogs. This disease is characterised by the death of bone tissue in the femoral head due to an interruption of its blood supply. The lack of blood flow leads to the collapse of the femoral head and subsequent degenerative changes in the coxofemoral joint, resulting in pain and lameness.
