What is it?

A condition in which the bone begins to die when the blood supply to the ball part of the hip joint (femoral head) is temporarily interrupted.

The weakened bone gradually breaks apart and loses its round shape. Eventually, the body restores blood supply to the ball and it heals. The ball can cause pain and stiffness if it is no longer round after it heals. It can take several years for bones to die, fracture, and renew.

Your doctor may move your child's legs into different positions during the physical exam to check range of motion and see if any positions cause pain.




A snug fit between the femoral head and the socket is necessary for this molding to work. Leg casts that keep the legs spread widely apart for four to six weeks can sometimes accomplish this.

To keep the ball of the joint snug within the socket, some children require surgery. Realigning the joint may require wedge-shaped cuts on the thigh bone or pelvis.
