Abstract：
BACKGROUND: Osteoarthritis is a disabling pathology characterised by joint pain and stiffness. A prevalence of coxarthrosis of 7.4% is reported in our country. Total hip joint replacement is indicated in advanced stages, a procedure that is not free of complications, the most frequent being prosthetic dislocation, which can be prevented with dual mobility systems. The following study aims to determine the rate of complications and clinical outcomes in dual mobility systems in primary coxarthrosis.
METHODS: A retrospective study included 120 cases in 114 patients diagnosed with grade III coxarthrosis, mean age was 62.43 years, with a mean follow-up of 4.5 years. Joint replacement was performed by Hardinge approach. All cases were assessed clinically using the Harris Hip Score (HHS) and radiologically to demonstrate mid-term results.
RESULTS: The preoperative value on the HHS scale had a mean of 56.45, postoperative at one month 74.23; 6 months 85.40; 1 year 94.01 and at 5 years 94.84 points, representing a functional improvement of 17.78 postoperative month; 28.95 at 6 months postoperative; 37.56 at one year postoperative and 38.39 points at 5 years postoperative. A complication rate of 3.44%; 0.86% of complications were associated with the prosthetic components.
CONCLUSIONS: The dual mobility system should be considered as a therapeutic option in primary hip joint replacement due to excellent functional results and low complication rates.
METHODS: IV. Retrospective observational case series study.

摘要：
背景：骨关节炎是一种以关节疼痛和僵硬为特征的致残病理。据报道，我国髋关节病的患病率为7.4％。全髋关节置换术在晚期阶段，一个并非没有并发症的程序，最常见的是假肢脱位，这可以防止与双移动系统。以下研究旨在确定原发性关节病双移动系统的并发症发生率和临床结果。
方法：一项回顾性研究包括114例诊断为III级髋关节病的患者中的120例，平均年龄为62.43岁,平均随访4.5年。采用Hardinge入路进行关节置换。使用Harris髋关节评分（HHS）和放射学对所有病例进行临床评估，以证明中期结果。
结果：HHS量表的术前平均值为56.45，术后1个月74.23；6个月85.40；1年94.01和5年94.84分，代表功能改善术后17.78个月;28.95在术后6个月;37.56在术后1年和38.39点在术后5年。并发症发生率为3.44%；0.86%的并发症与假体部件相关。
结论：由于具有出色的功能效果和较低的并发症发生率，因此应考虑将双移动系统作为初次髋关节置换的治疗选择。证据四级.回顾性观察性病例系列研究。
