M91: Juvenile osteochondrosis of hip and pelvis
M91.1: Juvenile osteochondrosis of head of femur [Legg-Calvé-Perthes]
The two hip joints connect the pelvis to the thighbones (femurs). At each side of the pelvic bone there is a depression. This depression is also called the hip socket. The femoral head sits in the hip socket. The femoral head is the rounded, top end of the femur.
If bone tissue has died off, it can be painful. You may also no longer be able to move the affected area properly. The tissue around the affected bones may be swollen.
Bone tissue can die off if does not get a good supply of blood. If bone tissue has died off, the affected bone may become misshapen. The bone may also then stop growing as well.
