摘要
目的:探讨股骨远端骨折行锁定钢板术后发生内固定失败的原因。方法:分析15例股骨远端骨折术后内固定失败的原因,均再次手术、植骨、内固定。结果:术后平均随访时间12个月(8～20个月)。术后8个月,所有病例骨折均愈合。HSS评分为81～100分,平均(90.6±2.3)分,和术前(71.5±4.8)分比较差异有统计学意义(P<0.01)。关节活动度正常者13例,屈膝活动受限者2例,但均<10°。结论:锁定钢板固定不恰当、复位不充分、骨折固定的原则和方法不正确、钢板选择不恰当及患肢负重过早可能是股骨远端骨折行锁定钢板术后发生内固定失败的主要原因。
Objective：To investigate the failure cause for treatment of fractures of distal femur with locking plate.Method：15 cases of failure of fractures of distal femur with locking plate were analyzed,and reoperated with internal fixation,with bone graft.Result：Average follow-up was 12 months（range from 8 to 20 months）.Fractures were united within 8 months after operation in all cases.The HSS score was 81 to 100,with an average of 90.6±2.3,and significantly increased compared to 71.5±4.8 before operation（P0.01）.The range of motion was normal in 13 patients.Flexion deficit was found in 2 cases,but within 10°.Conclusion：The main causes of failure for treatment of fractures of distal femur with locking plate include incorrect fixation of locking plate,insufficient reduction,incorrect principle and method of fracture fixation,incorrect choice of plate,and postoperatively earlier weight-bearing.
