摘要:

背景:初次全髋关节置换后脱位是仅次于假体松动的主要并发症之一。关于后外侧入路全髋关节置换时关节囊和外旋肌群是否需要修复,学术界存在争议。

目的:探讨采用髋关节后外侧入路进行初次人工全髋关节置换时修复后关节囊及外旋肌群对预防髋关节后脱位的临床意义。
方法:回顾性分析接受后外侧入路初次全髋关节置换的髋部原发性或继发性骨关节炎患者的临床资料,根据置换过程中不同的软组织修复策略分为2组,对照组不进行后方软组织修复,联合修复组进行关节囊及短外旋肌群的修复。所有患者置换后均已随访超过1年,定义置换后1 年内发生的关节脱位为早期脱位。比较不同修复方法对早期脱位率的影响。
结果与结论:共有362例患者,计390例次初次全髋关节置换纳入研究,共发生早期脱位7例,其中对照组6例次(2.2%,6/268),而修复组1例次(0.8%,1/122),比较发现修复组和对照组患者的早期脱位率差异有显著性意义,对照组患者髋关节早期脱位率显著高于修复组(P=0.012)。提示对于后外侧入路的初次全髋关节置换,联合修复后方关节囊和短外旋肌群可降低置换后早期脱位率。

Abstract:

BACKGROUND: Primary dislocation after total hip arthroplasty is a major complication, besides prosthesis loosening. It is controversial whether joint capsule and external rotators should be repaired during total hip arthroplasty through posterolateral approach.

OBJECTIVE: To explore the clinical significance of joint capsule and external rotator repair on preventing hip dislocation after primary total hip arthroplasty through posterolateral approach.
METHODS: Clinical data of patients with primary or secondary hip osteoarthritis after primary total hip arthroplasty through posterolateral approach were retrospectively analyzed. They were assigned to two groups according to different strategies of soft tissue repair. Control group did not receive posterior soft tissue repair. Combined repair group received the repair of joint capsule and short external rotators. All patients were followed up for more than 1 year. Early dislocation was defined as the dislocation occurred within 1 year after operation. The effects of different repair methods on early dislocation rate were compared.
RESULTS AND CONCLUSION: There were 362 patients. Totally 390 case-times of primary total hip arthroplasty were included. Early dislocation occurred in 7 cases, of which 6 case-times in the control group (2.2%, 6/268), and 1 case-time in the repair group (0.8%, 1/122). There were significant differences in the incidence rate of early dislocation between the repair group and control group (P=0.012). These findings confirmed that the combined repair of posterior joint capsule and short external rotators could decrease the rate of early dislocation after primary total hip arthroplasty through posterolateral approach.
