ng to the standards of hip function evaluation of Huang Gongyi.The group without bone graft：excellent for 14 cases，good for 9 cases，fair for 4 cases and poor for 3 cases.There were 7 cases of coxa vara，2 cases of hip screw cutsout，1 case of collapse of internal fixation and 2 cases of fracture nonunion.76.7％showed excellent or good result.The group with bone graft：excellent for 18 cases，good for 9 cases，fair for 2 cases and poor for 1 case.There were 3 cases of coxa vara，1 cases of hip screw cutsout and no case of collapse of internal fixation or fracture nonunion.90.0％showed excellent or good result.Conclusion The application of preventive bone graft in the operation of IFF by DHS can hasten the growth of fracture，quickly reconstruct the medial support structure of hip and reduce the incidence of coxa vara and the other related complications.
Key wors：intertrochanteric femur fractures；dynamic hip screw；internal fixation；bone graft
股骨粗隆间骨折是一种高能量损伤，多见于老年人，损伤机制复杂。动力髋螺钉(dynamic hip screw，DHS)治疗股骨粗隆间骨折，允许骨折端动态加压，能够最大限度地稳定固定骨折，有效减少骨折相关并发症的发生［1］，成为治疗股骨粗隆间骨折的金标准［2］。但DHS内固定本身亦存在缺点，如术后可出现小粗隆内侧失稳致髋内翻、头颈旋转、头颈切割穿钉、钢板拔钉及钢板断裂等现象。为探讨植骨在降低DHS内固定失败率方面的作用，2004～2007年，我院采用动力髋关节螺钉治疗Evans分型Ⅰ～Ⅳ型股骨粗隆上一页 [1] [2] [3] [4] [5] 下一页
