后外侧微创切口全髋置换术与常规全髋置换术疗效比较

目的比较后外侧微创切口全髋置换术与常规全髋置换术的疗效，并分析后外侧微创切口全髋置换术在临床应用上的优缺点。方法选择48例需全髋关节置换患者随机分为微创组和对照组各24例，微创组采用后外侧微创切口全髋置换术治疗，对照组采用常规全髋置换术治疗。记录患者的性别、年龄、体重、手术时间、术中术后出血量、切口长度、术后开始功能锻炼时间、术后Harris评分、并发症等。随访时间为3～18个月，平均12个月。结果微创组在术中术后出血量、手术切口长度、术后开始功能锻炼时间显著低于对照组（P〈0．05），在术后Harris评分、术后并发症等方面比较差异无统计学意义。结论采用后外侧微创切口全髋置换术进行人工全髋置换可明显缩短手术时间，降低术后并发症及假体位置不当的风险，具有手术创伤小，失血量少，可以早期进行关节功能锻炼等优点。

Comparison between modified posterolateral mini-incision approach and the traditional lateral approach in the total hip arthroplasty

Objective To compare the effect between the modified posterolateral mini-incision approach and the traditional post-lateral approach in the total hip arthroplasty, and study the advantages and limitations of the minimal incision surgery in clinical application. Methods Forty-eight patients received total hip arthmplasty were randomly divided into two groups, 24 cases using the modified posterolateral mini-incision approach in total hip arthoop- lasty（minimal incision group）, and other 24 eases using the traditional lateral approach （contiol group）. The patients＇ sex, age, weight, operative time, intraoperative blood loss and postoperative drainage volume, incision length, intraoperative and postoperative fractures, the initial time of postoperative functional exercises time, postoperativeHarris score, postoperative hip dislocation and other complications were recorded. The follow-up time lasted 3 to 18 months, with an average of 12 months. Results The intraoperative and postoperative blood loss, incision length and the initial time of postoperative functional exercise in the mini-incision control group were significantly less than those in the control group （ P 〈 0. 05 ）. There were no significant difference in the intraoperative and postoperative fractures ,postoperative hip dislocation, postoperative Harris score and postoperative complications. Conclusion The modified posterolateral mini-incision approach in total hip arthroplasty can shorten the operation time and reduce the risk of postoperative complications and improper prosthetic position. In the early postoperative stages, the advantages of mini-incision approach were small surgical trauma, less blood loss and early joint exercise.
