1. The corrected position of the femur following operative fusion of the hip joint is on the average not maintained. This is true to a lesser extent following subtrochanteric osteotomy.
2. The greatest loss of correction occurs during the first few months after operation, before firm union has been established.
3. Solid bony union following hip fusion is a slow process, necessitating prolonged and careful fixation if the corrected position is to be maintained. This is the most important period of the postoperative treatment, the period which decides the success of the corrective procedure.
