经后方传统及微创全髋关节置换切口的比较研究

Comparative study of posterior and traditional approaches for minimally invasive total hip replacement

目的比较经后方传统及微创全髋关节置换入路的临床疗效。方法由同一组手术医生行传统切口全髋关节置换50例,微创切口全髋关节置换36例。比较两种不同入路的手术时间、出血量、术后并发症、术后12周Harris评分及假体的位置、血沉及c-反应蛋白。结果所有病例均获得随访,出血量、术后并发症、术后12周Harris评分及假体的位置、术后疼痛评分经统计学处理差异无统计学意义(P>0.05)。在传统入路血沉及C-反应蛋白较高(P<0.05)。结论传统及外侧微创全髋关节入路均体现了满意的临床疗效,微创入路创伤较小。

Objective To compare the clinical effect of posterior and traditional approaches for minimally invasive total hip replacement. Methods All operations were performed by the same surgeon . Fifty cases were performed with traditional approach,36 cases with MIS THA . The average follow-up period was 12 weeks. The surgical time,intra-operative blood loss, Harris hip score, component malpositioning and complications were compared between the two approaches, Results There were no differences between the two approaches with regard to operating time, Harris hip score, component malpositioning and major complications. Statistically significant differences were found in two groups in terms of blood sedimentation,and C-reaction protein. Conclusion Both approaches can be effectively performed without increasing risk of complications. Significant benefits of MIS posterior approach include less soft tissue damage.
