Peri-prosthetic shoulder infection (PSI), a highly disabling complication of shoulder arthroplasty, often requires additional surgery and prolonged antibiotic therapy. Of strategies proposed to manage this devastating condition, the use of cement spacers, perhaps even as a definitive treatment, is debated.
QUESTIONS/PURPOSES: We sought to systematically review the literature on antibiotic-loaded cement spacers as a viable, perhaps definitive, treatment for PSI, evaluating the eradication rates, mechanical reliability, and functional results related to its use.
We conducted a systematic review of studies published from January 1, 1980, through September 1, 2019. Following the and Preferred Reporting Items for Systematic Review and Meta-analysis, we searched for studies reporting functional and clinical outcomes in patients with PSI treated with a permanent spacer of the shoulder. Two independent reviewers searched eight databases, as well as reference lists of the retrieved articles.
After exclusion criteria were applied, 12 studies were included, involving a total of 143 patients. The mean age was 65.8 years; the mean follow-up was 37.4 months. A total of 133 patients (93%) were free from infection at latest follow-up. The mean post-operative active elevation of the shoulder ranged from 48.6 to 90°, the mean abduction ranged from 51 to 75°, and external rotation ranged from 3.6 to 29°. The mean Constant-Murley score ranged from 20.6 to 42 points (out of 100, from worst to best).
The use of a permanent cement spacer is a reliable solution to PSI in low-demand, older patients with comorbidities, a population in whom it is desirable to avoid additional surgery. Our review found a high rate of infection eradication and moderate-to-good objective and subjective results. However, the overall level of evidence of included studies was very low, and higher-quality studies are needed to clarify the role of permanent spacers in the treatment of PSI.
人工肩关节周围感染（PSI）是肩关节置换术一种严重致残的并发症，常需再次手术及延长抗生素治疗时间。在为应对这一灾难性状况而提出的策略中，使用骨水泥间隔物（甚至可能作为一种确定性治疗方法）存在争议。
问题/目的：我们试图系统回顾关于载抗生素骨水泥间隔物作为PSI一种可行的、甚至可能是确定性治疗方法的文献，评估与其使用相关的根除率、机械可靠性及功能结果。
我们对1980年1月1日至2019年9月1日发表的研究进行了系统回顾。按照系统评价和Meta分析的 及优先报告项目，我们搜索了报告使用肩关节永久性间隔物治疗的PSI患者功能和临床结果的研究。两名独立评审员搜索了八个数据库以及检索到文章的参考文献列表。
应用排除标准后，纳入12项研究，共涉及143例患者。平均年龄为65.8岁；平均随访时间为37.4个月。在最近一次随访时，共有133例患者（93%）无感染。术后肩关节平均主动抬高范围为48.6至90°，平均外展范围为51至75°，外旋范围为3.6至29°。Constant-Murley平均评分范围为20.6至42分（满分100分，从最差到最佳）。
对于需求较低、患有合并症的老年患者，使用永久性骨水泥间隔物是解决PSI的可靠方法，这类人群希望避免再次手术。我们的综述发现感染根除率较高，客观和主观结果为中度至良好。然而，纳入研究的总体证据水平非常低，需要更高质量的研究来阐明永久性间隔物在PSI治疗中的作用。
