先天性髋内翻手术方法的选择

摘要

@@ 先天性髋内翻是一种不太多见的先天性畸形.临床表现酷似先天性髋关节脱位:单侧者,跛行;双侧者,"鸭步".另外还表现臀部扁平,会阴增宽.尤其突出的表现为患侧下肢内收活动幅度增大,而外展活动受限.%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.
