Shoulder Prosthetic Infection and Humerus Osteomyelitis From Cutibacterium Following Eden-Hybinette Procedure.

We describe the case of a patient who recently underwent a guided arthroscopic Eden-Hybinette procedure for the revision of a previous failed procedure of Latarjet and resurgence of shoulder instability. The subsequent development of painful infectious arthritis of the left shoulder complicated by osteomyelitis of the humerus, caused by Cutibacterium acnes, and accompanied by high fever was resolved only after the removal of synthetic screws and bone grafting and thanks to prolonged intravenous antibiotic treatment. The antibiotic regime was continued, both intramuscularly and orally, after discharge, allowing the full healing of the severe osteoarticular infection of the shoulder.
