不同排列方式空心螺钉治疗股骨颈骨折的疗效分析

摘要

目的：探讨不同排列方式空心螺钉治疗股骨颈骨折的临床效果。方法收集2010年3月至2014年5月在我院治疗并符合标准的160例股骨颈骨折患者的临床资料，根据空心螺钉排列方式的不同将患者分为正三角组和倒三角组，记录并比较2组患者手术时间、术中出血量、术中透视次数、住院时间、骨折愈合时间、术后并发症、Harris 评分及髋关节功能等。结果倒三角组手术时间、术中出血量明显低于倒三角组，差异具有统计学意义（P ＜0．05）；倒三角组股骨颈短缩率为10％，正三角组为26．3％，2组差异具有统计学意义（P ＜0．05），2组患者术中平均透视次数、住院时间、骨折愈合时间、骨折不愈合率、股骨头坏死率、Harris 评分及髋关节功能优良率差异均无统计学意义（P ＞0．05）。结论空心螺钉倒三角排列治疗股骨颈骨折手术操作更为简单，手术时间短、术中出血量小，术后短缩发生率低。%Abstact:Objective To explore the effect of different arrangement of hollow screws in treatment of femoral neck fracture.Methods The clinical data of 160 cases with femoral neck fracture from March 2010 to May 2014 in our hospital were collected.They were randomly di-vided into triangle group and inverted triangle group according to arrangement of hollow screws.The operation time,intraoperative blood loss, fluoroscopy frequency in operation,length of stay,time of fracture healing,postoperative complications,Harris score and functional recovery of two groups were recorded and compared.Results The operation time and intraoperative blood loss in inverted triangle group were lower than those in triangle group,the difference was significant(P <0.05).The shortening rate of inverted triangle group and triangle group were 10%and 26.3% respectively.The shortening rate of inverted triangle group was lower than those of triangle group,the difference was significant (P <0.05).For the fluoroscopy frequency in operation,average hospitalization time,fracture healing time,rate of nonunion and femoral head necrosis,Harris score and functional recovery,there was no statistical significance between two groups(P >0.05).Conclusion Inverted tri-angle hollow screws treating femoral neck fracture makes surgery operation easier,operative time shorter and blood loss smaller.
