摘　　要：目的:探讨InterTAN拉力螺钉前倾角对老年股骨粗隆间骨折患者术后功能的影响。方法:选择接受闭合复位InterTAN内固定治疗的43例股骨粗隆间骨折患者。根据拉力螺钉与股骨颈轴心线在髋关节侧位片上夹角的大小,分为拉力螺钉前倾角正常组和非正常组,比较两组骨折愈合时间、疼痛视觉模拟量表(VAS)评分、Harris髋关节功能评分及并发症发生率。结果:术后两组VAS评分(2.30±1.21 vs.2.24±1.35)、Harris髋关节功能评分比较(83.92±3.81 vs.81.76±5.69),差异均无统计学意义(P>0.05)。术后复查X线片,两组骨折愈合时间相比较(3.56±7.12 vs.3.62±4.34),差异无统计学意义(P>0.05)。前倾角非正常组的并发症发生率虽然高于前倾角正常组(16.67%vs.8.00%),但P=0.695>0.05,差异无统计学意义。结论:InterTAN拉力螺钉前倾角在一定范围内增大或变小对股骨粗隆间骨折患者术后骨折愈合及髋关节功能恢复无明显影响。Objective: To observe the effect of anteversion angle of interTAN intramedullary nail on the post-operative function recovery in elderly patients with intertrochanteric fractures of femur. Methods: Forty-three patients with femoral intertrochanteric fractures undergoing internal fixation by closed reduction and InterTAN intramedullary nail were included,and allocated to normal angle group and abnormal angel group according to the angle degree measured between the nail position and axis of the femoral neck.Then the two groups were compared concerning the time of fracture healing,scoring on Visual Analogue Scale(VAS),Harris Hip Joint Scale(HHS) and post-operative complications. Results: The two groups were not significantly different in scoring on VAS(2.30±1.21 vs .2.24±1.35)and HHS(83.92±3.81 vs .81.76±5.69) as well as fracture healing time(3.56±7.12 vs .3.62±4.34)(all P> 0.05).Although patients in abnormal anteversioon angle group had higher incidence of complications than those in the normal anteversion angle group,yet the difference was insignificant(16.67% vs .8.00%, P= 0.695>0.05). Conclusion: Increased or decreased anteversion angle of interTAN intramedullary nail within a certain limit will not notably affect postoperative hip function recovery and the fracture healing time in patients with intertrochanteric fractures of femur.
