How does Legg-Calve-Perthes disease cause hip pain in children?

ANSWER

If the rounded top of the thighbone (femoral head) that fits into the hip socket (pelvis) doesn’t get enough blood, the bone is more likely to break. It also won’t heal as well as a healthy bone would. This can cause your child to limp or have stiffness and pain in the hip, knee, or thigh.

Doctors don’t know why blood stops flowing to the hip joint in some children. It’s more common among kids up to age 8. Boys are more likely to have it. Doctors can treat it with crutches, a cast, physical therapy, or surgery.

Having Legg-Calve-Perthes disease after age 6 makes someone more likely to have hip problems as an adult.
