Combined Procedure of Open Reduction and Shortening of the Femur in Treatment of C.D.H. in Older Children / 대한정형외과학회잡지

ABSTRACT

Older children with neglected ongenital dislocation of the hip is not easily reduced. Even if reduction is achieved, the overstretched muscle tends to resume its original length, provoking either a redilocation or a pressure necrosis with resultant stiffness of the hip joint and deformity. The authors treated 15 cases of the C.D.H. in older children by combined procedure of open reduction, Salter's innominate osteotomy, and femoral shortening with redirection of the femoral head. The results were obtained in 15 operated hips with follow-up from 1 to 5 and 3/12 years. l. We had good results in 11 among 15 cases(73%). 2. Femoral shortening was spontaneously correctd 1.3cm in 1 year, 2.1cm in 2 years follow-up. 3. The improvement of acetabular index following Salter's innominate osteotomy was about 12.4 degrees. 4. We had no serious complication such as avascular necrosis, stiffness, and redislocation, but 3 cases of mild limitation of hip joint motion were noted. 5. Two skin incision were more convenient in operative procedure and handling of instruments than one incision(Klisić).
