摘　　要：目的探讨股骨转子下截骨矫形、动力髋或髁螺钉系统固定治疗股骨近段纤维结构不良（fibrous dysplasia，FD）伴髋内翻畸形的临床疗效。方法回顾性分析2001年4月至2010年5月收治的26例股骨FD伴髋内翻畸形患者的临床资料，男9例，女17例；年龄10－53岁，中位年龄19岁。单骨型14例，多骨型12例。病灶长度为多骨型9-36cm（平均19cm），单骨型7-15cm（平均9cm）；17例合并病理性骨折；术前颈于角65°～110°（平均92°），患肢短缩1．5－4．5cm（平均2．8cm）。21例病灶累及股骨颈者采用髋螺钉固定，5例未累及股骨颈者采用髁螺钉固定。结果手术时间80-170min（平均120min），出血量280-1650ml（平均960ml）。术后颈干角为119°-140°（平均127°）；患肢平均延长2．3cm（1．5-3．6cm）。随访9-118个月（平均39个月），截骨面均愈合。除1例颈干角从术后126。减小到术后56个月的115°，其余患者无髋内翻畸形复发，无内固定断裂或松动。1例股骨颈变短、髋螺钉沿滑槽滑动，但螺钉未切割股骨头；1例术后7年外伤后钢板远端处股骨干骨折。根据Guille的功能评价标准，24例满意、2例不满意。结论转子下截骨矫形、动力髋或髁螺钉系统内固定能有效地纠正股骨上段FD伴髋内翻畸形，改善患肢功能。Objective To investigate the clinical effect of subtrochanteric osteotomy plus dynamic hip/condyle screw （DHS / DCS） fixation to treat the fibrous dysplasia of the proximal femur with coxa vara. Methods Twenty-six clinical cases of femoral fibrous dysplasia with coxa vara were retrospectively analysed from April 2001 to May 2010. There were 9 males and 17 females, with a median age of 19 （10 to 53）. Forteen patients presented with monostotic disease, and 12 with polyostotic disease. The length of the lesion for polyostotic disease was from 9 cm to 36 cm, while for monostotic disease was from 7 cm to 15 cm. Seventeen cases were merged with pathologic fracture. The neck shaft angles were from 65 to 110 degree pre- operation. The shortage of limbs was from 1.5 cm to 4.5 cm. Twenty-one patients involved in femoral neck were fixed with DHS and the other 5 cases with DCS. Results The duration of operation was from 80 to 170 min. The amout of bleeding was from 280 to 1650 ml with the average of 960 ml. The average postoperative neck shaft angles were 127 degree （119 to 140）. The shortened limbs were extended 2.3 cm for average （1.5 to 3.6 cm）. The follow-up time was from 9 to 118 months with the average of 39 months. All patients with osteotomy were healed. The neck shaft angle of 1 case decreased from post-operative 126° to 115° 56 months post-operatively, no coxa adducta recurrented and all internal fixations were in position. Hip screw backed out through the barrel in one case with the shortage of femoral neck. One case had femoral fracture after an injury. According to Guille function standard, 24 cases were regarded as satisfied and 2 cases as unsatisfied. Conclusion Subtrochanteric osteotomy plus DHS/DCS fixation can effectively correct the fibrous dysplasia of the proximal femur with coxa vara, and significantly improve the function.
