微创与常规全髋关节置换术临床疗效的比较

目的探讨微创与常规全髋关节置换术（total hip arthroplosty，THA）临床疗效。方法全髋关节置换术20例，按治疗方法不同分为髋关节前外侧小切口THA（微创组）10例和常规后外侧THA（常规组）10例；观察两组病例的手术时间、出血量、切口长度、并发症、术后疼痛程度、术后功能评价等。结果微创组优3例，良4例，中2例，差1例；常规组优2例，良3例，中3例，差2例。两组优良率比较差异有统计学意义（χ2=3．984，P〈0．05）；微创组术中出血量、引流量、输血量、切口长度[（315．5±223．1）ml、（259．5±170．1）ml、（88．5±13．2）ml、（9．9±0．4）cm]与常规组[（520．5±219．7）ml、（517．9±212．7）ml、（359．1±31．5）ml、（15．8±2．1）cm]有显著性差异（均P〈0．05）；微创组手术时间、术后3个月Harris评分与常规组无显著性差异（均P〉0．05）。结论微创全髋关节置换术，具有创伤小、出血少、安全、并发症少等优点。

Comparison of clinical efficacy for total hip arthroplasty by minimally invasive operation and conventional way

Objective To investigate the clinical efficacy of minimally invasive way for total hip arthroplasty(THA). Methods Twenty cases of THA were performed with minimally invasive anterolateral surgical approach(MIS group,n=10)and conventional posterolateral surgery(conventional group,n=10),respectively.The operation time,blood loss,incision length,complications,postoperative pain,postoperative functional evaluation were compared between two groups. Results The curative effects in MIS group were excellent in 3 cas...
