I have to have my shoulder replaced. What can I expect?
Of course, the best thing to do is to discuss this with your own doctor, but there are some general things that you can expect.

Your shoulder is made of a socket and ball, as well as muscles, tendons, and ligaments that hold it all together. The ball part in the replacement is generally made of metal. This is attached to your humerus either with a straight fit or with bone cement. This ball fits into the socket, which is called the glenoid component.

After the surgery, you will likely have to use a sling to keep the weight of your arm from pulling on the shoulder. A physiotherapist will show you how to strengthen your arm and shoulder and your doctor will tell you when you can stop using your sling. It is very important that you follow the instructions closely to increase the chance of a successful surgery.
