Ninety-day mortality after shoulder arthroplasty.

Although mortality associated with knee and hip arthroplasty has been reported, there is no information about shoulder arthroplasty. The purpose of this study was to determine the incidence and risk factors associated with perioperative mortality after shoulder arthroplasty. Between 1970 and 2000, 2,953 patients underwent shoulder arthroplasty at our institution. A retrospective review identified all patients who died within 90 days of the procedure. The 90-day mortality incidence was 0.58% (17 of 2,953). Twelve hemiarthroplasties were performed for a pathologic fracture and one for rotator cuff arthropathy. Total shoulder arthroplasties were performed for the sequelae of trauma (2), rheumatoid arthritis (1), and avascular necrosis (1). Ninety-day mortality was closely associated with the underlying diagnosis. Perioperative mortality after shoulder arthroplasty for non-neoplastic conditions is low.
