【摘要】 目的探讨老年股骨粗隆间骨折手术中DHS(动力髋螺钉)、PFNA-Ⅱ(防旋股骨髓内钉)内固定的应用效果。方法选取我院2012年12月~2015年12月收治的老年股骨粗隆间骨折患者90例,按照数字随机分组法,将患者分成实验组、对照组,各45例。实验组为PFNA-Ⅱ内固定,对照组为DHS内固定,比较两组的骨折恢复效果、手术时间、术中出血量、开始负重时间、住院时间以及并发症。结果 (1)骨折恢复优良率:实验组为95.56%,对照组为77.78%,差异有统计学意义(P<0.05)。(2)实验组的术中出血量、住院时间、负重时间、手术时间与对照组相较,差异有统计学意义(P<0.05)。(3)并发症率:实验组为2.22%,对照组为15.56%,差异有统计学意义(P<0.05)。结论在老年股骨粗隆间骨折手术中,采用PFNA-Ⅱ内固定的效果更好,手术损伤相对较小,值得临床推广。更多还原

【Abstract】 Objective To investigate the elderly femoral intertrochanteric fracture surgery DHS(dynamic hip screw),PFNA-Ⅱ(anti spin femoral intramedullary nail) and application effect of internal fixation. Methods Our hospital in December 2012-90 elderly patients with intertrochanteric fracture patients admitted in December 2015 were studied,according to figures randomization method,the patients divided into experimental group,45 cases in each group.Experimental group within PFNA-Ⅱ fixed,fixed to the control group within the DHS,the two groups of fractures recovery effect,operative time,blood loss,weight-bearing time,hospital stay and complications. Results(1)fracture restore was: the experimental group was 95.56%,the control group was 77.78%,compared with statistical significance(P<0.05).(2)experimental group of intraoperative blood loss,hospitalization time,load time,operation time compared with the control group were statistically significant(P<0.05).(3)complications rate: the experimental group was 2.22%,the control group was 15.56%,with significant difference(P<0.05). Conclusion In the old age femoral intertrochanteric fracture in the operation,the PFNA-Ⅱ fixation effect better,surgical injury is relatively small,worth clinical promotion.更多还原
