N2  - Abstract: 
  We previously evaluated ninety-four patients (ninety-six shoulders) who underwent reverse shoulder arthroplasty with use of a central compressive screw along with 5.0-mm peripheral locking screws for baseplate fixation and a center of rotation lateral to the glenoid. The purpose of this study was to report updated results at a minimum follow-up of five years. Since the last report, an additional two patients underwent revision surgery: one for recurrent instability and one for resorption of a proximal humeral allograft. The patients continue to have improved outcome scores and range of motion. Survivorship with the end point being revision for any reason was 73.5 months, with 94% survival at sixty months. Radiographic follow-up showed that two (3%) of seventy-six patients included in the survivorship analysis had asymptomatic humeral loosening, seven (9%) had scapular notching, and no patient had glenoid baseplate loosening or baseplate failure. The patients have maintained their improved function with durable clinical and radiographic results at a minimum of five years.Level of Evidence:
