Isolated shoulder sepsis is an uncommon clinical problem with little information in the literature on causative organisms
and potential sequelae. We examined the organisms involved, surgical treatments, antibiotic treatments rendered, and complications
in these cases. We retrospectively reviewed the records of 19 adult patients (19 shoulders) who underwent operative treatment
of isolated shoulder sepsis from 1996 to 2005. Patient age, gender, laboratory studies, previous treatment, surgical procedures,
surgical findings, cultured organism, antibiotic treatment, and complications were reviewed. The organisms included methicillin-susceptible
Staphylococcus aureus (five), Streptococcus B beta hemolytic (five), Staphylococcus epidermidis (three), negative cultures
(two), Streptococcus viridans (one), Escherichia coli (one), methicillin-resistant S. aureus (one), and Propionibacterium
acnes (one). We treated patients with intravenous antibiotics an average of 4.2 weeks (range, 3–8 weeks). One patient underwent
humeral head resection with an antibiotic spacer. Another patient died during hospitalization. Open or arthroscopic débridement
in conjunction with appropriate antibiotics appears effective in eradicating infection in most adults who present with shoulder
sepsis. Functional outcome is poor in those patients with irreparable rotator cuff tears and/or cartilage loss.
