前、后外侧入路对髋关节置换术后深静脉血栓及脱位的影响

目的评估前外侧与后外侧入路对初次全髋关节置换术后深静脉血栓及脱位的影响。方法自2007年1月～2011年9月，将入选的初次全髋关节置换患者随机分为前外侧组及后外侧组，各50例。观察患者术后深静脉血栓及髋关节脱位的发生情况。结果随访时间为15～50个月，平均29个月。术后深静脉血栓发生率：前外侧组（16％）高于后外侧组（8％），比较无显著性差异（P〉0．05）；术后髋关节脱位发生率：前外侧组（0）低于后外侧组（10％），比较有显著性差异（P〈0．05）。结论不同手术入路对初次髋关节置换术后深静脉血栓及关节脱位有一定的影响。

The Effect of Deep Venous Thrombosis and Dislocation in Total Hip Arthroplasty with Anterolateral Approach and Posterolateral Approach

Objective To evaluate the effect of deep venous thrombosis （DVT） and dislocation in primary total hip arthroplasty （THA） with anterolateral approach group and THA with posterolateral approach group. Methods From January 2007 to September 2011, patients primary treated with THA were selected which we divided into anterolateral approach group and posterolateral approach group, each group with 50 patients. We observed the happening of DVT and dislocation of hip after surgery. Results All the patients were followed up from 15 months to 50 months （29 months on average）. The postoperative incidence rate ofDVT： anterolateral approach group （16%） was higher than posterolateral approach group （8%）, but it showed no significant differences （P〉0.05）; The postoperative incidence rate of dislocation of hip： anterolateral approach group （0） was lower than posterolateral approach group （10%）, it showed significant differences （P〈0.05）. Conclusion Different surgical approach has different effect on DVT and hip dislocation for the patient treated with THA.
