When it comes to possibly needing shoulder arthroplasty, or replacement—there are a number of different options for each patient situation. This page’s information will focus on what is commonly referred to as a TSA, or Total Shoulder Arthroplasty. This procedure includes surgery for the placement of a prosthesis made of humeral and glenoid components. The surgery can last hours, and as a result will require patient sedation along with regional anesthesia.
The Shoulder is: A ball-and- socket joint consisting of the humerus (ball), clavicle (collarbone), and scapula (shoulder blade). The joint’s socket is formed by a shallow grove called the glenoid, and is where the humerus connects.
