Artificial shoulder replacement is considered if all other alternatives are unsuccessful. The decision to replace the shoulder is a joint decision between you and your physician. There are approximately 40,000 shoulder replacements performed annually in the United States.
In addition to a complete medical history, your physician may perform a complete physical examination, including x-rays, to ensure you are in good health before undergoing surgery. In addition, you may also meet with a physical therapist to discuss rehabilitation after the surgery and undergo blood tests (or other tests).
A shoulder prosthesis is made up of metal and plastic. There are two types – a cemented prosthesis and an uncemented prosthesis. The cemented type is attached to the bone with a type of epoxy. The uncemented prosthesis is held in place by a tight press fit, allowing the bone to grow into the mesh surface and attaching naturally to the prosthesis. Your surgeon will determine the most appropriate prosthesis for you.
The prosthesis (artificial shoulder) is made of two components:
While in the hospital, the shoulder will be in a shoulder splint or immobilizer to protect and position the shoulder. However, patients may begin to use their hand and wrist for simple activities. The usual length of stay is one to two days in the hospital with discharge to home. Activity and pain management details will be discussed prior to discharge.
