目的 比较InterTAN髓内钉(IT)与动力髋螺钉(DHS)治疗股骨转子间骨折的疗效.方法 选择行手术治疗的股骨转子间骨折患者56例,根据手术方式不同分为IT组21例和DHS组35例,比较两组术中情况(手术时间、术中出血量、切口长度、住院时间)、术后并发症(伤口感染、下肢深静脉血栓、褥疮、尿路感染、肺炎)和骨折愈合情况(骨折愈合时间、股骨颈短缩、髋内翻及髋关节Harris评分).结果 IT组手术时间、术中出血量、切口长度和住院时间均明显优于DHS组[(62.16±15.26) min比(85.78±19.50) min、(237.73±108.51) ml比(490.87±127.90) ml、(10.20±2.02) cm比(19.83±2.98) cm和(10.23±5.52)d比(15.58±5.32)d,P＜ 0.01],两组术后并发症比较差异无统计学意义(P＞0.05).IT组股骨颈短缩和髋内翻发生率明显少于DHS组[9.52％(2/21)比28.57％(10/35)和14.29％(3/21)比31.43％(11/35),P＜0.01],在骨折愈合时间及髋关节Harris评分方面两组比较差异无统计学意义(P＞0.05).结论 与DHS相比,IT的应用范围更广,手术时间明显缩短,且固定可靠,更适用于治疗股骨转子间骨折.“,”Objective To evaluate the clinical effect of InterTAN (IT) and dynamic hip screw (DHS) in treatment of femoral intertrochanteric fractures.Methods From July 2008 to November 2011,the patients with femoral intertrochanteric fractures were treated by IT (IT group,21 patients) and DHS (DHS group,35 patients).The intraoperative data (operative time,intraoperative blood loss,incision length and hospitalization period),postoperative complications (wound infection,lower limb deep venous thrombosis,bedsore,urinary tract infection and pneumonia) and fracture healing (fracture healing time,femoral neck crispation,coxa vara and Harris scores) were compared.Results IT group was superior to DHS group in operative time,intraoperative blood loss,incision length and hospitalization period [(62.16 ± 15.26) min vs.(85.78 ± 19.50) min,(237.73 ± 108.51) ml vs.(490.87 ± 127.90) ml,(10.20 ±2.02) cm vs.(19.83 ± 2.98) cm and (10.23 ±5.52) d vs.(15.58 ±5.32) d,P ＜0.01].However,there was no significant difference in postoperative complications (P ＞ 0.05).There was significant difference between IT group and DHS group in femoral neck crispation,coxa vara [9.52％ (2/21)vs.28.57％ (10/35),14.29％ (3/21)vs.31.43％ (11/35),P ＜ 0.01].There was no significant difference in fracture healing time and Harris scores (P ＞ 0.05).Conclusions Compared with DHS,IT has extensive application,shorter surgical time and reliable fixation effect.Therefore,IT is suitable to femoral intertrochanteric fractures.
