Perthes disease

Perthes disease is the idiopathic avascular osteonecrosis of the capital femoral epiphysis of the femoral head, also known as Legg-Perthes Disease and Legg-Calve-Perthes disease (LCPD). In more lay terms, it is caused by an interruption to the blood supply of the head of the femur close to the hip joint.

Symptoms

Symptoms are hip or groin pain, exacerbated by hip/leg movement. There is a reduced range of motion at the hip joint and a painful gait. There may be atrophy of thigh muscles from disuse and an inequality of leg length. In some cases, some activity can cause severe irritation or inflammation of the damaged area including standing, walking, running, kneeling, or stooping repeatedly for an extended period of time.
