➢ Shoulder periprosthetic joint infection (PJI) is a potentially devastating complication after arthroplasty and is projected to rise with increasing numbers of performed arthroplasties, particularly reverse shoulder arthroplasties.➢ Important considerations for the diagnosis and treatment of shoulder PJI include age, sex, implant type, primary compared with revision shoulder surgery, comorbidities, and medications (i.e., corticosteroids and disease-modifying antirheumatic drugs). ➢ Diagnosis and management are unique compared with lower-extremity PJI due to the role of lower-virulence organisms in shoulder PJI, specifically Cutibacterium acnes.➢ Treatment pathways depend on chronicity of infection, culture data, and implant type, and exist on a spectrum from irrigation and debridement to multistage revision with temporary antibiotic spacer placement followed by definitive revision arthroplasty.

肩关节假体周围关节感染：预防、诊断和治疗原则。


➢ 肩关节假体周围感染 （PJI） 是关节置换术后潜在的破坏性并发症，预计随着关节置换术数量的增加，尤其是反向肩关节置换术，感染率会上升。诊断和治疗肩关节 PJI 的重要考虑因素包括年龄、性别、植入物类型、与翻修肩关节手术相比的初次手术、合并症和药物（即皮质类固醇和改善病情的抗风湿药）。➢ 由于低毒力微生物在肩部 PJI 中的作用，特别是痤疮杆菌，与下肢 PJI 相比，诊断和管理是独特的。治疗途径取决于感染的慢性性、培养数据和植入物类型，存在于从冲洗和清创到多阶段翻修与临时抗生素垫片放置后确定性翻修关节置换术的范围内。
