How does the hip grow back?
Although the blood supply to a part or all of the femoral head is disrupted and stops the femoral head from growing, healing will occur over time since tissue around the affected part of the femoral head is alive and is able to respond to the abnormal change. In many patients, especially those with early onset of the disease (before age 6), normal growth is restored. In older patients, restoration of normal growth of the hip is not as predictable.
