Application and Efficacy Observation of PFNA in the Treatment of Intertrochanteric Fractures

股骨转子下骨折是指股骨干峡部即成人股骨小转子至远端5 cm之间的骨折。流行病学调查显示,髋部骨折患者中约7%~34%累及转子下。这一区域应力集中,治疗比较棘手,如果内固定材料选择不当容易出现内固定失败、骨折延迟愈合或不愈合等并发症。股骨近端抗旋髓内钉(Proximal Femoral Nail Antirotation,PFNA)是近年来研制的一种新型抗旋髓内固定材料,是在股骨近端髓内钉(Proximal Femoral Nail,PFN)基础上研发的,具有以下优点:① PFNA内固定主钉跨越大段股骨,增加了髓内壁接触面积,使应力可平均分散;② PFNA缩短了其到股骨头中心的垂直距离,相对减少了断裂机会;③ PFNA主钉金属可承受较大负荷强度,使患者术后可早期进行功能锻炼和负重,有利于功能恢复。我院近年来应用PFNA治疗股骨转子周围骨折,疗效较好,报道如下。
