What is total shoulder replacement surgery?
Patients frequently ask, "What exactly is a total shoulder replacement?" The simplest answer is that it is a replacement of the worn and arthritic surfaces of the shoulder joint or as a solution for certain fractures very close to the joint.
A total shoulder replacement replaces the worn or damaged parts of the joint by fixing an artificial surface to all parts that contact each other as the shoulder moves and lifts the arm.
The shoulder is a ball-and-socket joint, consisting of the humeral head (the "ball"), the glenoid fossa (the "socket") and the shoulder capsule, or tissue that surrounds the joint.
A shoulder replacement removes the damaged parts of the shoulder, replacing them with artificial components.
The implants, which are made of some combination of metal and plastic come in a variety of sizes and are fitted to the bone to provide an artificial surface that causes no pain when the shoulder is used.
These parts may be fixed to the bone with or without cement.
