外展推移截骨术治疗先天性髋内翻

Long Term Follow Up of Children with Congenital Coxa Vara After Valgus Osteotomy

目的：分析转子间外展推移截骨术治疗先天性髋内翻的远期疗效。方法：用转子间外展推移截骨术治疗先天性髋内翻２０例（２７髋），平均随访１４年。结果：所有股骨头骺板早期闭合，大转子上移，大部分髋臼发育不良，股骨头球形适应改变，肢体短缩。结论：手术可以使股骨头骺板处在正常位置上，但不能使股骨头骺板内部异常生长得到控制。股骨头骺板的早期闭合是骺板损伤后修复的结局。

Objective: The purpose of this study is to evaluate the long term results of valgus subtrochanteric osteotomy for congenital coxa vara. Methods: Valgus subtrochanteric osteotomy was carried out on 27 congenital coxa vara hips(twenty patients). The average duration of follow up was 14 years. Results: Early closure in the proximal femoral epiphysis, short femoral neck and greater trochanter overgrowth were found in all patients post operatively. Most of them were associated with acetabular dysplasia, loss of spherical contour of femoral head and short limbs. Conclusion: The valgus osteotomy, while corrects the anatomical position of femoral head and neck, may affect the subsequent bony growth.
