Review Question - QID 219880

A 64-year-old male presents to the clinic for continued management of left shoulder pain. He has previously attempted physical therapy, over-the-counter analgesics, and intra-articular injections with minimal improvement. On examination, his rotator cuff strength is 5/5. His active forward flexion is 130 degrees, while internal and external rotation is 45 degrees, all of which are reduced compared to the contralateral extremity. Repeat radiographs are obtained, as depicted in Figure A. Which of the following characteristics would necessitate glenoid component augmentation while performing total shoulder arthroplasty?
