股骨近端抗旋髓内钉在股骨转子周围骨折中的应用

目的 总结股骨近端抗旋髓内钉(PFNA)治疗转子周围骨折的临床经验,探讨其临床疗效.方法 2006年3月-2008年9月使用PFNA治疗136例转子周围骨折患者,骨折均为闭合型.手术使用骨科牵引床、C形臂影像增强器,采用闭合复位或有限切开复位、锁定技术.结果 136例经10～18个月随访,平均14.5个月,所有患者均获得骨性愈合.根据Harris髋关节评分,129例(94.9%)为优良.结论 PFNA治疗股骨转子周围骨折手术创伤小、并发症少、固定更稳定,是股骨转子周围骨折理想的内固定物.

Treatment of intertrochanteric fractures with proximal femur nail antirotation

Objective To summarize the experiences in treatment of intertochanteric fractures with proximal femur nail antirotation (PFNA). Methods A retrospective study was done on 136 patients with intertrochanteric fractures treated with PFNA from March 2006 to September 2008. Postoperative reduction quality, long-term radiographic results and function of hip were evaluated separately. All the patients had closed fractures. The operation involved orthopedic traction bed, C-arm image intensifier,closed reduction or limited open reduction and locking technique. Results All patients were followed up for 10-18 months (average 14.5 months), which showed fracture healing in all patients. According to Harris criterion, the function of the hip joint obtained excellence in 129 patients ( 94.9% ). Conclusion PFNA has advantages of simple procedure, minimal invasion, firm fixation and early functional exercises and is an effective method for treatment of intertrochanteric fractures.
