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.
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。
