目的：总结侧卧位防旋股骨近端髓内钉（PFNA）治疗股骨粗隆间骨折的临床疗效。方法：回顾性分析2014年6月-2016年6月我科收治的采用PFNA固定治疗的股骨粗隆间骨折患者72例的临床资料，根据患者体位不同分为对照组（n=39，平卧位）与观察组（n=33，侧卧位），比较两组患者的手术时间、术中出血量、术前术后血红蛋白（Hb）差。结果：观察组与对照组的手术时间[（70.1±11.5）vs（72.7±9.6）min]、术中出血量[（113.8±37.8）vs（129.2±20.7）ml]、术前术后Hb差[（18.1±3.7）vs（17.2±5.5）g/L]均无统计学意义（P＞0.05）。结论：侧卧位下PFNA治疗粗隆间骨折的临床疗效好，节省术前牵引床准备时间，为无骨科牵引床医院采用PFNA治疗股骨粗隆骨折提供依据。“,”Objective:To summarize the clinical effect of proximal femoral nail antirotation(PFNA) treating intertrochanteric fracture in lateral position. Methods:The clinical data of 72 patients with intertrochanteric fracture treated by PFNA were retrospectively analyzed from Jun 2014 to Jun 2016.The cases were divided into control group (n=39,horizontal position)and observation group(n=33,lateral position)according to different position. The operation time,intraoperative blood loss and hemoglobin difference before and after operation were compared between the two groups. Results: The operation time,intraoperative blood loss and hemoglobin difference in the observation group were not significant difference in the control group [(70.1±11.5)min vs(72.7±9.6)min,(113.8 ±37.8)ml vs(129.2±20.7) ml and[(18.1 ±3.7)g/L vs(17.2±5.5)g/L ,all P>0.05]. Conclusions:PFNA treatment for intertrochanteric fracture in lateral position has good clinical effect,saving the preoperative traction bed preparation time,providing methods for treatment of intertrochanteric fractures with PFNA for basic hospital without orthopedic traction bed.
