Review Question - QID 216847

A 79-year-old male presents to your office with shoulder pain that has been present for many years. He states he had a previous rotator cuff tear that had been treated with injections and physical therapy by another surgeon. However, his pain is no longer controlled and he is ready to move forward with surgery. Radiographs demonstrate arthropathy of the glenohumeral joint and biconcavity of the superior glenoid. Given the most likely surgery performed in this patient, what position should he be counseled to avoid post-operatively to prevent dislocation?
