Actual (reported)The goal of this study is to compare the effect of different ways to place the component that goes at the top of the humerus (upper arm) in reverse total shoulder replacement. Some surgeons place the humeral tray component sitting on the bone while others place it in the bone. Changing the way that the humeral component is placed may change how much the arm can raise up or turn out/in after surgery for some patients. This study compares patients with inlay humeral component (tray sits in the upper arm bone) versus onlay humeral component (tray sits on top of the upper arm bone) to see if there are differences in range of motion or function after surgery.
