Total Shoulder Arthroplasty
The goal of conventional shoulder replacement is to remove the rough surfaces and bone spurs created by the arthritic process and replace them as anatomically as possible. The humeral side has many options including canal sparing, short stem (shown on right), and long stem designs. The glenoid component is polyethylene and cemented to the bone. The front rotator cuff tendon (subscapularis) must be cut and repaired at the end of the surgery and must be protected postoperatively. I am not a proponent of physical therapy after any shoulder replacement surgery in the first three months after surgery.
