A consecutive series of 49 patients who had a primary total hip arthroplasty (THA) for osteoarthritis is reviewed to determine the difference in clinical outcome between the direct lateral and the posterior surgical approaches to the hip. Group 1 comprised 28 patients off had THA by the same surgeon using a posterolateral approach. Group 2 comprised 21 patients who had THA using the direct lateral approach, modified from Hardinge. The improvement in the limp, abductor strength, Trendelenburg test, and range of motion over time was similar in the two groups. The average Harris hip score at 1 year was 90 for Group 1 (posterior approach) and Group 2 (lateral approach). At 2-year minimum follow up, the Harris hip score was 94 for both groups. Radiographic review showed that the incidence and severity of heterotopic bone was also similar for both groups. The authors conclude that the clinical and radiographic outcome for THA using the posterior and the lateral approaches to the hip yield similar clinical results.
回顾了连续49例因骨关节炎接受初次全髋关节置换术（THA）的患者，以确定髋关节直接外侧入路和后外侧手术入路的临床结果差异。第1组包括28例由同一位外科医生采用后外侧入路进行THA的患者。第2组包括21例采用改良自哈丁格（Hardinge）的直接外侧入路进行THA的患者。两组患者随着时间推移在跛行、外展肌力量、特伦德伦伯格试验（Trendelenburg test）和活动范围方面的改善情况相似。第1组（后外侧入路）和第2组（外侧入路）在1年时的平均哈里斯髋关节评分均为90分。在至少2年的随访中，两组的哈里斯髋关节评分均为94分。影像学检查显示，两组异位骨的发生率和严重程度也相似。作者得出结论，髋关节THA采用后外侧入路和外侧入路的临床和影像学结果相似。
