人工全髋关节置换术后关节脱位的相关影响因素分析

Analysis on Related Influencing Factors of Joint Dislocation after Total Hip Arthroplasty

目的 分析人工全髋关节置换(THA)术后关节脱位的相关影响因素。方法 选取2019年5月至2021年4月于我院行THA治疗的260例患者,依据关节脱位与否分为未脱位组(235例)与脱位组(25例)。收集患者的一般资料,统计患者手术情况及术后康复情况,并采用多因素Logistic回归分析导致其关节脱位的相关危险因素。结果 经单因素分析显示,脱位组的年龄及后外侧入路、假体放置在安全区外、术后搬运情况不恰当、术后制动不严格占比均高于未脱位组(P<0.05)。经Logistic回归分析显示,年龄偏高、后外侧入路、假体放置在安全区外、术后搬运情况不恰当、术后制动不严格是导致THA术后关节脱位的危险因素(OR>1, P<0.05)。结论 年龄偏高、后外侧入路、假体放置在安全区外、术后搬运情况不恰当、术后制动不严格是THA术后关节脱位的影响因素,临床应据此制定个性化的干预措施,预防THA术后关节脱位的发生。

Objective To analyze the related influencing factors of joint dislocation after total hip arthroplasty(THA).Methods 260 patients undergoing THA in our hospital from May 2019 to April 2021 were selected and divided into non-dislocation group(235 cases)and dislocation group(25 cases)according to joint dislocation or none.The general data of patients were collected,and the operation status and postoperative rehabilitation were counted.Multivariate Logistic regression was used to analyze the related risk factors of joint dislocation.Results Univariate analysis showed that the age and the proportion of posterolateral approach,prosthesis placement outside the safe area,improper postoperative handling and lax postoperative braking in the dislocation group were higher than those in the non-dislocation group(P<0.05).Logistic regression analysis showed that high age,posterolateral approach,prosthesis placement outside the safe area,improper postoperative handling and lax postoperative braking were the risk factors of joint dislocation after THA(OR>1,P<0.05).Conclusions High age,posterolateral approach,prosthesis placement outside the safe area,improper postoperative handling and lax postoperative braking are the influencing factors of joint dislocation after THA.The clinical personalized intervention measures should be formulated to prevent the joint dislocation after THA.
