Shoulder Periprosthetic Joint Infection: Principles of Prevention, Diagnosis, and Treatment

Abstract

➢ 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.
