Review Question - QID 216837

A 73-year-old female presents to your clinic with complaints of persistent shoulder pain and weakness over the last year. She notes a history of proximal humerus fracture 5 years ago which was treated with hemiarthroplasty. She had been doing well up until the past year, when she noticed marked decrease in range of motion and strength. On examination, she has 2/5 strength of her shoulder in abduction and flexion and can abduct and flex her shoulder to only 70º. Her radiograph is seen in Figure A. She states her symptoms are significantly affecting her quality of life. Given these findings, what is the best treatment option at this time to regain function and improve her quality of life?
