摘要 目的:探讨动力髋螺钉(DHS)的前倾角对治疗股骨转子间骨折疗效的影响。方法:用DHS治疗股骨转子间骨折患者97例,根据髋螺钉与股骨颈轴心线在髋关节侧位片上夹角的大小,将其分为髋螺钉前倾角正常组和非正常组,进行跟踪随访,并记录骨折愈合的时间,髋内翻、髋螺钉切割股骨头骨折再移位和髋关节疼痛及股骨头坏死的发生率。结果:随访12~36个月,平均28个月。骨折愈合时间:前倾角正常组为(58±6.9)d,非正常组为(89±15.7)d。两组间行t检验,具有统计学意义(P<0.05)。前倾角正常组髋内翻、髋螺钉切割股骨头骨折再移位、髋关节疼痛及股骨头坏死的发生率明显低于非正常组。结论:动力髋螺钉的前倾角对治疗股骨转子间骨折疗效有着重要的影响。 Objective:To research on the effect of anteversion angle of hip screw in the treat-ment of intertrochanteric femoral fracture(IFF).Methods :In the study,97cases of IFF treated with DHS were divided into two groups by the angle between hip screw and axis of the femoral neck:nor-mal anteversion angle group and abnormal group.Both groups were analyzed and followed up for12~36months,averaging28months,and the time of union,hip inversion,redisplacement by screw incising,pain of hip,and femoral head necrosis were all recorded.Results:Union time was58±6.9d in normal anterior angle group versus89±15.7d in abnormal group.T test was conducted between the two groups(P<0.05)showing significant difference.Rates of hip inversion,redisplacement by screw incising,pain of hip,and femoral head necrosis in normal group were lower than those in the abnormal group.Conclu-sions :The anteversion angle of dynamic hip screw has important effects on the treatment of IFF.
