小切口人工全髋关节置换术50例临床疗效分析

目的探讨应用外侧小切口行人工全髋关节置换术的临床疗效。方法选择本院2006年4月至2009年4月全髋关节置换术手术患者100例，随机分为观察组和对照组，观察组行外侧小切口全髋关节置换术，对照组行常规人工全髋关节置换术。记录两组患者手术时间、手术出血量、引流量、输血量以及切口长度；观察两组患者术后关节功能的恢复情况；对两组患者治疗前和治疗后进行Harris评分。结果观察组切口长度、术中出血量、引流量、输血量分别与对照组比较，差异有统计学意义，P〈0．05；两组患者术后Harris评分比较，差异无统计学意义，P〉0．05。结论外侧入路小切口行人工全髋关节置换术，手术创伤小，术后早期功能恢复快，但须严格掌握手术适应证。

Clinical efficacy of mini-incision for total hip arthroplasty in 50 cases

Objective To explore the clinical efficacy of lateral mini-incision for total hip arthroplasty.Methods 100 cases who needed total hip arthroplasty were selected from April 2006 to April 2009.they were divided into two groups, control group and observation group. Routine operation for total hip arthroplasty was used to control group,lateral mini-incision for total hip arthroplasty was used to observation group. Operative time、preoperative bleeding、drainage flow 、transfusion volume、incisional lengthwere recorded, and postoperative functional recovery in two groups were observed; and scores of harris was evaluated in two groups before and after operation. Results incisional length、preoperative bleeding、drainage flow 、transfusion volume in two groups existed statistical difference, P<0.05; after operation, scores of Harris in two groups existed no statistical difference,P > 0.05.Conclusion mini-incision for total hip arthroplasty with lateral approach has advantage of minimal invasion、quickly functional recovery, but the Indication of operation should be mastered.
