Review Question - QID 217373

A 65-year-old female presents to your clinic complaining of a longstanding history of right shoulder pain, which has persisted despite physical therapy, activity modification and oral NSAIDs. She notes that an intra-articular corticosteroid injection performed by her primary care physician four months ago provided greater than 90% pain relief. On physical examination, she has well-preserved forward flexion, external rotation with her arm at the side and at 90 degrees of abduction and internal rotation. Her radiographs and MRI can be seen in Figures A and B, respectively. Given this patient's history and imaging, which complication is she at an increased risk of experiencing should she undergo an anatomic total shoulder arthroplasty (TSA)?
