This article presents a case of metallosis following a reverse total shoulder arthroplasty. Patient dislocated seven months postoperatively and with concern of further instability as noted on examination, the patient was taken to the operating room for glenosphere and liner exchange. During surgery, severe metallic staining was discovered in the joint as well as significant inferomedial wear to the polyethylene insert. This was likely due to instability as a result of inadequate tension on the deltoid muscle, inadequate liner size, early hypermobility, downward tilt of the glenoid and failure to lateralize the component sufficiently. It is hypothesis that the glenoid component articulated with the metal humeral neck due to asymmetric polyethylene wear of the humeral cup. This likely led to metal-on-metal wear and allowed the release of metal ions into the local environment...
