Technical and patient care improvements have occurred with the posterior mini-incision total hip arthroplasty. We hypothesized that these changes would provide better results for patients. The clinical and radiographic results of 100 total hip arthroplasties done with the posterior mini incision between January 2004 and October 2004 were compared with 100 mini-incision total hip arthroplasties done between December 2001 and September 2002. There were no differences in diagnosis, age, and body mass index of the patients in each group. Component positions were not compromised in either group. There were improvements in the 2004 group with decreased hospital stay, reduction of postoperative pain and opioid analgesic use, reduced use of assistive devices, and earlier muscle recovery. In the 2004 group there were no complications of infection, dislocation, or sciatic palsy. The posterior mini-incision operation has shown improved results with experience and changes in technique and patient care treatment.

后路小切口全髋关节置换术在技术和患者护理方面已有改进。我们假设这些改变会为患者带来更好的结果。将2004年1月至2004年10月采用后路小切口进行的100例全髋关节置换术的临床和影像学结果，与2001年12月至2002年9月进行的100例小切口全髋关节置换术进行比较。每组患者的诊断、年龄和体重指数均无差异。两组的假体位置均未受影响。2004年组有改善，住院时间缩短、术后疼痛减轻、阿片类镇痛药使用减少、辅助装置使用减少以及肌肉恢复更早。2004年组无感染、脱位或坐骨神经麻痹并发症。随着经验的积累以及技术和患者护理治疗的改变，后路小切口手术已显示出更好的结果。
