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.

Investigations

X-Rays of the hip joint are absolutely necessary. A bone scan may be useful in helping determine the extent of the avascular changes. A hip aspiration may be performed if there is suspicion of a septic arthritis.
