Surgery to stabilize the bone with pins or screws will prevent further slippage or displacement of the ball of the hip joint. Some surgeons may offer to pin the unaffected hip at the same time, because many children will develop a slip of this hip as well.
The outcome is usually good with treatment. However, in rare cases, the hip joint may degenerate. Most experts agree that this is due primarily to a displacement of the growth plate, followed by a disruption of the blood supply to the ball of the hip. Because this is related to the severity of the condition itself, the joint may degenerate despite prompt recognition and treatment.
This disorder is associated with a greater risk of osteoarthritis later in life. Other potential but rare complications include diminished blood flow to the hip joint and thinning of the cartilage in the hip joint.
If your child experiences persistent pain or other symptoms suggestive of this disorder, have the child lie down immediately and remain still until medical attention has been obtained.
