锁定接骨板治疗不稳定性股骨转子间骨折

目的 总结股骨近端锁定接骨板(locking proximal femoral plate,LPFP)治疗不稳定性股骨转子间骨折的临床疗效. 方法股骨不稳定性转子间骨折32例,根据Evans分型:Ⅲ型16例,Ⅳ型10例,Ⅴ型6例.采用LPFP固定.观察骨折愈合情况,参照Harris髋关节评分系统评定术后患髋功能. 结果全部32例患者获得平均12.5个月随访,所有骨折均愈合.无髋内翻及内固定失败,无股骨头缺血性坏死.按Harris髋关节评分标准:优良率84%. 结论 LPFP具有符合股骨近端解剖形态、固定牢靠、对股骨头血供干扰小等优点,是一种较好的固定不稳定性股骨转子间骨折的内置物.

Treatment of unstable femoral intertrochanteric fractures with locking proximal femoral plate

Objective To investigate the efficacy of locking proximal femoral plate (LPFP) in treatment of unstable femoral intertrochanteric fractures. Methods A total of 32 patients with unstable femoral intertrochanteric fractures were operated via Watson-Jones approach. According to the Evans classification, there were 16 patients with type Ⅲ fractures, 10 with type Ⅳ fractures and 6 with type Ⅴ fractures. The data of bone healing time and hip function scores according to Harris hip function score system were recorded for evaluating treatment outcomes. Results All the patients were followed up for an average 12.5 months, which showed fracture union within mean 10.4 weeks. There were no hip varus deformation, internal fixation failure and avaacular necrosis of femoral head, with total excellence rate of 84% according to Harris hip function score system. Conclusions LPFP is characterized by correspondence with configuration of proximal femur, stable fixation, less disturb to blood supply of femoral head, and hence is an effective treatment method for unstable femoral intertrochanteric fractures.
