[目的]比较直接前入路与后外侧入路人工全髋关节置换术治疗老年股骨颈骨折的短期临床疗效.[方法] 2015年1月～2016年12月采用直接前方入路(direct anterior approach,DAA)技术行全髋关节置换术12例,其中女7例,男5例,年龄72～86岁,乎均(78.70±3.60)岁.另按纳入标准随机抽取17例后外侧入路全髋关节置换术病例作为对照.[结果] DAA组手术切口(8.61±1.22) cm,比后外侧组(12.51±1.65) cm小;手术时间(95.02±10.14) min,比后外侧组(72.05±11.57) min长;术中出血量(155.01±26.03) ml,比后外侧组(220.03±32.53) ml少;术后引流量(109.11±15.52) ml,比后外侧组(158.97±21.82) ml少;差异均具有统计学意义(P＜0.05).术后6个月髋关节Harris评分DAA组为(92.51±5.83)分,与后外侧组(91.88土6.32)分相比差异无统计学意义(P＞0.05).[结论]DAA全髋关节置换,不仅切口小、术中出血量少,且利于置换术后早期功能锻炼.“,”[Objective] To compare the short-term clinical results of direct anterior approach (DAA) and posterolateral approach in total hip arthroplasty (THA) for treatment of femoral neck fracture in the elderly.[Methods] From January 2015 to December 2016,12 patients (12 hips) underwent THA through DAA,including 7 females and 5 males aged from 72 years to 86 years with an average of (78.7 ± 3.6) years.In addition,17 patients who had THA through the routine posterolateral approach were randomly selected as the control group.[Results] The length of incision of the DAA group [(8.61±1.22)cm] was shorter than the posterolateral group [(12.51 ± 1.65) cm],however,the operation time of the DAA group [(95.02± 10.14)min] was longer than the posterolateral group [(72.05 ± 11.57)min].The intraoperative bleeding of the DAA group [(155.01 ± 26.03)ml was less than the posterolateral group [(220.03±32.53)ml],and the postoperative drainage of the DAA group [(109.11 ± 15.52)]ml,was also less than the posterolateral group[(158.97±21.82)ml].There were statistically significant differences in all of the above parameters between the two groups (P＜0.05).Nonetheless,no significant difference was found in the Harris score between the two groups [DAA group (92.51±5.83),posteolateral group (91.88±6.32),P＞0.05] at 6 months postoperatively.[Conchsions] THA through DAA has advantages of not only the small incision,but also less perioperative blood loss,which facilitate early functional recovery.
