Infection is a rare but serious complication of shoulder arthroplasty. The most prevalent cause of patient infections is (formerly ), a commensal skin bacterial species. Its presentation is often non-specific and can occur long after shoulder arthroplasty, leading to delay in diagnosis. This bacterium is difficult to culture, typically taking 14 to 17 days for a positive culture and often does not exhibit abnormal results on a standard laboratory workup for infection (eg, ESR, CRP, and synovial WBC count). Male patients are at particularly high-risk due to having a greater number of sebaceous follicles than females. While it is difficult to diagnose, early diagnosis can lead to decreased morbidity, appropriate treatment, and improved clinical outcomes. Current options for treatment include antibiotics, one stage implant exchange, or two stage implant exchange, although success rates of each are not currently well described. A better understanding of the prevention, diagnosis, and treatment of infection could lead to better patient outcomes from shoulder arthroplasty.
感染是肩关节置换术一种罕见但严重的并发症。患者感染最常见的原因是（以前称为），一种皮肤共生细菌。其表现通常不具有特异性，可在肩关节置换术后很长时间出现，导致诊断延迟。这种细菌很难培养，通常需要14至17天才能培养出阳性结果，并且在标准的感染实验室检查（如血沉、C反应蛋白和滑膜白细胞计数）中往往不会出现异常结果。男性患者由于皮脂腺毛囊数量比女性多，感染风险特别高。虽然很难诊断，但早期诊断可降低发病率、进行适当治疗并改善临床结果。目前的治疗选择包括抗生素、一期植入物置换或二期植入物置换，尽管目前每种方法的成功率尚无详细描述。更好地了解感染的预防、诊断和治疗方法，可能会使肩关节置换术患者获得更好的治疗效果。
