摘要
目的探讨PFNA治疗不稳定型股骨转子间骨折的方法及疗效。方法 2006年12月～2008年6月,采用PFNA治疗不稳定型股骨转子间骨折35例,男16例,女19例;年龄62～91岁,平均75.6岁。受伤原因:步行跌伤26例,交通伤9例。AO分型:A2型21例,A3型14例。所有患者均经骨科下肢牵引床牵引闭合复位,微创置入PFNA。结果平均手术时间55min(35～120min)。术中平均失血量130ml(30～500ml)。随访时间9～36个月随访,平均19.6个月。术后部分负重时间2～12d,平均6.8d。35例患者伤口均一期愈合,无一例出现皮缘坏死和伤口感染。骨折愈合时间9～20周,平均13.3周。全部患者的术后功能均恢复到伤前水平。5例患者主诉患侧臀部和大转子区疼痛;无螺旋刀片切出股骨头、髋内翻等并发症。结论 PFNA可以安全有效的固定不稳定型股骨转子间骨折。
Objective To explore the clinical outcome of unstable intertrochanteric fractures treated with the proximal femoral nail antirotation （PFNA）. Methods Thirty-five patients for unstable intertrochanteric fractures were treatment with PFNA from December 2006 to June 2008. There were 16 males and 19 females with an average age of 75.6 years （range from 62 to 91 years）. Mechanism of injury： pedestrian injury in 26 cases and traffic accident in 9 cases. According to AO classification, there were 21 cases in A2 type, and 14 cases in A3 types. All cases were reduced through longitudinal traction on the traction table and fixed with PFNA. Results The mean operative time was 55 min （35-120 min）. The mean operative blood loss was 130 ml （30-500 ml）. The mean time to partical weight-bearing was 6.8 d （2-12d）. The mean duration of follow up was 19.6 months （9-36 months）. The wound healing was smoothly in 35 patients. None edge of skin necrosis and none infection of skin. The average time of fracture healing was 13.3 weeks （9-20 weeks）. The post-operative function was recovered to premorbid status in all patients. Five patients complained of hip and great trochanteric pain. No varus or cut-out were observed during the follow-up period. Conclusion PFNA can fix unstable trochanteric fractures safely and effectively by minimal invasive technique.
