성인 고관절 내반고증의 전자간 외반 절골술

Abstract

Many cases of osteoarthritis of the hip are theoretically preventable if the predisposing deformity can be prevented or corrected before the osteoarthritis begins. Coxa vara is one of theses predisposing deformity. For many patients, intertrochanteric osteotomy relieve pain and allows more extensive procedures to be done late if necessary. We analyzed radiologic change and clinical results in 11 patients (4 developmental coxa vara and 7 Legg-Calve-Perthes disease sequelae ) who had undergone intertrochanteric valgus osteotomy for coxa vara from January 1988 to January 1996 and followed up between 2 and 10 years. The following results were obtained. 1. Pain relieved in 9 cases(82% 2. The leg lengthened average 1.70 cm (Preoperative average leg length discrepancy was 2.04 cm). 3. Trendelenburg sign was negative in 9 cases. 4. Femoral neck-shaft angle was corrected from a mean of 111.27 degrees to a mean of 130.73 degrees. 5. Head-trochanteric distance was corrected from a mean of-1.39 cm to a mean of + 0.52 cm.
