Shoulder fusion is not used as commonly as it once was. Shoulder replacement has replaced fusion in many cases. If you haven't already talked to your surgeon about a total shoulder replacement, you may want to ask about this as an option before shoulder fusion.

Shoulder fusion or arthrodesis is called a salvage procedure. The arm is saved from amputation but full shoulder motion isn't preserved. You may not have enough motion to swing a rope over your head or enough strength to wrestle a calf to the ground.

The fusion is done using metal plates and screws. The reconstruction plate is actually one normally used in the hip or pelvic area. It goes up along the outside of the upper arm and over the top of the shoulder along the bony ridge of the shoulder blade. Screws help compress the bones together to fuse the area. Sometimes bone grafts are used to fill in any spaces left open.

Your arm will be immobilized for at least eight to 10 weeks. Some doctors use a special abduction pillow. Others put the arm in a full cast from wrist to shoulder. Once there is evidence of fusion on X-ray, rehab exercises can begin.
