Review Question - QID 219911

A 73-year-old woman undergoes right reverse total shoulder arthroplasty with an onlay humeral implant component for an irreparable rotator cuff tear and advanced glenohumeral osteoarthritis after failing nonoperative management. She returns to the clinic for her 1-year follow-up, reporting a 2-week history of acute onset, severe right shoulder pain without any inciting incidents, trauma, or falls. On examination, she has tenderness over the scapular spine, with shoulder abduction limited due to pain. Plain radiographs are obtained and confirmed on computed tomography of the right shoulder (Figure A). What factor would have most effectively decreased this patient’s risk of developing this complication?
