Periprosthetic shoulder infection: an overview

[摘要] While more than 66000 prosthetic shoulder procedures were performed in 2011 in the United States, the rate of post-operative infection seems to remain stable with 0.98% of cases.1-3 However, when infection occurs, this complication is always devastating with significant clinical and socioeconomic consequences.2 The rate is higher after revision surgery than after a primary procedure and reaches close to 5% in cases of reverse shoulder arthroplasty (RSA).4,5 Patients undergoing primary RSA are found to have a six times greater risk of infection compared with patients having primary unconstrained total shoulder arthroplasty.6 Arthroplasties for trauma are more at risk of infection than those from other causes.6 Comorbidities such as coagulopathy, renal failure, diabetes, lupus erythematosus, rheumatoid arthritis, intra-articular steroid injections and corticosteroid therapy increase the risk of periprosthetic shoulder infection (PSI).7 PSI is the major cause for revision within the first two post-operative years after an arthroplasty.
