A slipped capital femoral epiphysis is a hip problem. The ball-shaped upper end of the thighbone (femur) slips at the area where the bone is growing. When this happens, the femur does not fit snugly in the hip socket.
This happens most often in teens during a growth spurt. This is a rapid increase in height. Rapid weight gain or an injury also can cause it. Your child may have hip or knee pain or may walk with a limp.
Your child will need surgery. The doctor will put a screw in the bone. This holds the bone in place and lets it heal. If not fixed, this problem can lead to early arthritis of the hip or worse problems.
