Abstract

Background: Acromioclavicular (AC) osteoarthritis (OA) is a frequent pathology of the shoulder in elderly patients. Drug injection plays an important role in treatment of AC OA. Literature has demonstrated excellent short-term results regarding shoulder function and pain. However, mid- to long-term results are lacking. The aim of this study was to assess the efficacy of a single intra-articular AC injection in patients with AC OA and to identify predictive factors for success.

Methods: A retrospective study was performed to analyze success rate, shoulder function, and pain perception after a single intra-articular injection in patients with AC OA. Success was defined as the absence of reinterventions such as additional injection or surgery. Outcome measures were 1-year success rate and clinical outcome scores of Numeric Rating Scale (NRS) for pain, Oxford Shoulder Score, and Subjective Shoulder Value.

Results: Ninety-eight patients participated in this study. At a median final follow-up of 0.8 years (interquartile range, 0-6), 57 of these patients (58%) had undergone a reintervention. The 1-year success rate was 47% (95% confidence interval, 37%-57%), with NRS at rest as the sole factor significantly associated with success. Thirty patients not requiring reintervention reported significant improvement from baseline for all reported outcome measures at final follow-up.

Conclusions: AC injections offer a 1-year success rate of 47%. The AC injection produces good mid- to long-term clinical outcomes regarding shoulder function, quality of life, and pain perception in one-third of patients. Further research is essential to analyze mid- to longterm outcomes of AC injections. Level of evidence: Level IV.

肩锁骨关节炎患者肩锁骨注射的中长期成功率和功能结局。
背景:肩锁骨关节炎(AC)是一种常见的老年肩关节病变。药物注射在AC - OA的治疗中起着重要作用。文献证明了短期内对肩部功能和疼痛的良好治疗效果。然而,缺乏中长期的结果。本研究的目的是评估单次关节内注射AC对AC OA患者的疗效,并确定成功的预测因素。方法:回顾性研究分析AC OA患者单次关节内注射后的成功率、肩关节功能和疼痛感觉。成功的定义是没有再干预,如额外的注射或手术。结果测量为1年成功率、疼痛数值评定量表(NRS)临床结果评分、牛津肩部评分和主观肩部值。结果:98例患者参与本研究。在中位最终随访0.8年(四分位数范围0-6)时,其中57名患者(58%)接受了再干预。1年的成功率为47%(95%可信区间,37%-57%),静止状态下的NRS是唯一与成功率显著相关的因素。30例不需要再干预的患者在最后随访时报告所有报告的结果测量值较基线有显著改善。结论:交流电注射1年成功率为47%。在三分之一的患者中,AC注射在肩关节功能、生活质量和疼痛感知方面产生了良好的中长期临床结果。进一步的研究分析AC注射的中长期结果是必要的。证据等级:四级。
