目的 比较侧卧位直接前侧入路(DAA)与仰卧位DAA全髋关节置换手术的早期临床疗效.方法 选取2015年10月至2016年3月解放军沈阳军区总医院骨科收治的行髋关节置换手术的55例(60髋)患者.28例(30髋)患者采用侧卧位DAA,作为侧卧位组;27例(30髋)患者采用仰卧位DAA,作为仰卧位组.比较两组患者术前体质量指数、手术时间、手术前后血红蛋白下降程度、术后下床活动时间,及术后1、2、3个月的Harris评分.结果 术前两组患者体质量指数比较,差异无统计学意义(P>0.05).两组患者术后均无明显并发症发生.两组患者手术时间、手术前后血红蛋白下降程度、术后下床活动时间,术后1、2、3个月的Harris评分比较,差异均无统计学意义(P>0.05).结论 侧卧位DAA与仰卧位DAA术后的早期临床疗效比较无明显的统计学差异,但侧卧位DAA具有早期学习曲线短、手术时间短、无需专业的骨科手术床等优势.

Objective To compare the lateral position direct anterior approach(DAA)and supine position DAA in total hip arthroplasty(THA).Methods A retrospective study was performed on 55 patients(60 hips)who underwent THA from October 2015 to March 2016.There were 28 cases(30 hips)in lateral position DAA(lateral position group)and 27 cases(30 hips)in supine position DAA(supine position group).The preoperative BMI,operation time,hemoglobin decline before and after operation,postoperation activity time and Harris hip score of 1,2,3 months after operation was calculated.Results The comparison of the two groups had no significant differences of BMI(P>0.05).There was no obvious complication in the two groups.There was no statistically significant difference of operation time,hemoglobin decline before and after operation,postoperative activity time and Harris score after 1,2,3 months(P>0.05).Conclusion There is no significant difference of early clinical effect in the lateral position DAA and supine position DAA in THA,lateral position DAA has the advantages such as the early learning curve is short,the operation time is short,and no professional orthopedic bed is needed.
