改良拉钩在DAA全髋关节置换术中的临床应用研究

Clinical Application of Modified Retractor in DAA Total Hip Arthroplasty

目的:探讨改良拉钩在直接前入路(DAA)全髋关节置换术中的临床应用效果。方法:选择2018年6月~2019年7月行DAA全髋关节置换术的患者60例作为对象,随机数字表法均分为两组。对照组应用普通霍夫曼拉勾,观察组应用改良拉钩,统计患者手术时间、术中失血量、术后1周及1个月Harris评分。结果:两组患者手术时间无统计学意义(P>0.05);观察组肛门排气、住院时间、术中出血量、下床活动时间及术后进食时间均短(少)于对照组(P<0.05);两组患者Harris评分比较差异不明显(P>0.05)。结论:改良拉钩用于DAA全髋关节置换术中的创伤较小。

Objective:To investigate the clinical effect of modified retractor in direct anterior approach(DAA)total hip arthroplasty.Methods:A total of 60 patients who underwent DAA total hip replacement from June 2018 to July 2019 were selected as subjects and divided into two groups by random number table method.Ordinary Hoffmann hooks were used in the control group,and modified hooks were used in the observation group.The operative time,intraoperative blood loss,and Harris scores 1 week and 1 month after the operation were counted.Results:There was no significant difference in operation time between the two groups(P>0.05).In the observation group,the time of anal exhaust,hospital stay,intraoperative blood loss,time of getting out of bed and postoperative feeding were shorter(less)than those in the control group(P<0.05).There was no significant difference in Harris scores between the two groups(P>0.05).Conclusion:The modified retractor is less invasive in DAA total hip arthroplasty and is worthy of popularization.
