Combined procedure of open reduction and shortening of the femur in treatment of congenital dislocation of the hips in older children.

A one-stage, combined operative procedure for reduction of congenitally dislocated hips in older children consists of shortening of the femur; open reduction by an inferior approach to the joint; reconstruction of the acetabular roof; correction of anteversion of both the femoral neck and the neck-shaft angle; anterior transposition of the iliopsoas muscle. On 60 hips operated in children, ages 5 to 15 with a follow-up period, ranging from 5 to 9 years, the results were found to be excellent in 3 per cent, good in 60 per cent, fair in 30 per cent, and poor in 7 per cent. The procedure is indicated in children up to the time of early puberty. The primary indication is high bilateral dislocation. In unilateral dislocations some residual leg-length discrepancy frequently occurs. This procedure should be done only by orthopedic surgeons who have special training and experience in the treatment of congenital dislocation of the hip.
