Although reverse shoulder arthroplasty is used in massive rotator cuff tears, it is also used in proximal humerus fractures and shoulder arthroplasty revision. In this study, we aimed to examine the early radiological and clinical results of patients undergoing reverse shoulder arthroplasty with different diagnoses. Between 2010 and 2013, reverse shoulder arthroplasty was applied to 10 patients (4 men, 6 women) with the diagnosis of arthropathy due to rotator cuff tear (n: 7), multi-fragmentary proximal humerus fracture (n: 2) and hemiarthroplasty revision (n: 1). The median age of the patients was 74 (64-85) years and the median follow-up was 15.5 (3-35) months. Patients were assessed in terms of joint range of motion, Constant score and Visual Pain Scale (VAS) and radiological examinations before and after surgery. Preoperative active shoulder flexion, abduction, internal and external rotation degrees of the patients were 65, 30, 40 and 50 degrees, and 105, 95, 30, 57.5 degrees respectively in their final controls. Constant score was 20.5 (14-63) preoperatively, and 54.5 (38-64) in the final controls (p‹0.05). While the preoperative VAS was 7 (3-9), it was found to be 1.5 (1-3) in the final controls (p‹0.05). As a complication, scapular notching was observed in one patient. Internal external rotation values were better in the rotator cuff arthropathy group than the fracture group. Reverse shoulder arthroplasty, especially in the treatment of patients with rotator cuff arthropathy, has good early results and a low complication rate. We recommend paying attention to the glenoid component location to avoid scapular notching. [ABSTRACT FROM AUTHOR]
