Objective To investigate the effect of proximal femoral nail anti-rotation( PFNA) in the treatment of femo-ral intertrochanteric fractures in the elderly. Methods Thirty-eight elderly patients with intertrochanteric fractures were selected in this study. After anesthesia, manual reductions were carried out under C-arm fluoroscopically. After satisfactory reduction, PFNAs were inserted. While in those Evans type V or those with unsatisfactory reduction ca-ses, limited incisions were employed, and then PFNAs were inserted. Results The time of surgeries ranged from 30 minutes to 70 minutes. Blood losses during surgeries were 80~200 ml. No blood transfusion was needed during sur-geries. No drainage was used. All incisions were primary healing. All 38 cases were followed up from 6 months to 14 months. All the fractures got bony healing. A half centimeter′s migration of the spiral blade was noted in only 1 case, but still inside the bony structure, with subsequent mild coxa vara. DVT occurred in 2 cases,and 1 case suffered from brain infarction. Conclusions Treatment of elderly femoral intertrochanteric fractures with PFNA has less surgical trauma, shorter time of surgeries, less blood loss, stable fracture fixation, which is an ideal method.%目的：探讨股骨近端防旋髓内钉( PFNA)治疗老年股骨转子间骨折的效果。方法对38例老年股骨转子间骨折患者,在透视下复位,置入PFNA固定；对复位不满意或者EvansⅤ型患者行皮肤有限切开,置入PFNA固定。结果手术时间30~70 min,术中出血80~200 ml。患者术中未输血,未放置引流,伤口均一期愈合。38例均获得随访,时间6~14个月。骨折全部骨性愈合。1例螺旋刀片向外滑动约0．5 cm,但未切割出头,发生轻度髋内翻畸形；2例发生深静脉血栓,1例发生脑梗死。结论 PFNA治疗老年股骨转子间骨折创伤小,手术时间短,出血少,固定牢固,是一种理想的治疗方法。
