Selection of Surgical Treatments of Congenital Coxa Vara

From July, 1963 to June, 1979, 26 patients had been operated upon for coxa vara, including 35 deformed hip joints, forty operations were performed. Follow-ups were carried out for the results of 35 operations (on 32 hip joints). It seems that subtrochanteric abductive cuneiform osteotomy usually fails to prevent the recurrence of coxa vara because the angle of resection of the femoral shaft is apt to be insufficient. Following Langenskiold's osteotomy, i. e. intertrochanteric linear osteotomy with end-side fusion, coxa vara may recur when the steel wire becames loose whereas coxa valga may appear due to overcorrection of the neck-shaft angle of the femur. Btoh modified Amstuz-Wilson's osteotomy, i. e. subtrochanteric Z-shaped osteotomy with abduction impaction of the bone, and Borden-Spencer-Herndon's osteotomy, i. e. subtrochanteric linearosteotomy with side-end fusion, have proved fairly effective.
