The shoulder is a ball and socket joint. The round end of the arm bone fits into the opening at the end of the shoulder blade, called the socket. This type of joint allows you to move your arm in most directions.
For total shoulder replacement, the round end of your arm bone will be replaced with an artificial stem that has a rounded metal head (ball). The socket part (glenoid) of your shoulder bone will be replaced with a smooth plastic lining (socket) that will be held in place with special cement. If only 1 of these 2 bones needs to be replaced, the surgery is called a partial shoulder replacement, or a hemiarthroplasty.
Another type of procedure is called reverse total shoulder replacement. In this surgery, the positions of the ball and socket are switched. The round part of the shoulder is removed from the top of the arm, and a metal ball is attached to the shoulder bone. The socket is then attached to the arm bone. The ball ends up on the other side of the shoulder. This surgery can be done when the rotator cuff tendons are severely damaged or there are fractures of the shoulder.
For shoulder joint replacement, your surgeon will make an incision (cut) over your shoulder joint to open up the area. Then your surgeon will:
- Remove the head (top) of your upper arm bone (humerus).
- Place the new metal head and stem into place. It can sometimes be cemented in if the bone quality is poor.
- Smooth the surface of the old socket and cement the new one in place.
- Close your incision with staples or sutures.
- Place a dressing (bandage) over your wound.
Your surgeon may place a tube in this area to drain fluid that may build up in the joint. The drain will be removed when you no longer need it.
This surgery normally takes 1 to 3 hours.

- Ask your surgeon which medicines you should still take on the day of your surgery.
- If you have diabetes, heart disease, or other medical conditions, your surgeon will ask you to see the provider who treats you for these conditions to ensure that they are under control.

- Be sure to arrive at the hospital on time.
After the Procedure
After the procedure:
- You may stay in the hospital for 1 to 3 days after your surgery.
- While there, you may receive physical therapy to help keep the muscles around your shoulder from getting stiff.
- Before you go home, the physical therapist will teach you how to move your arm around by using your other (good) arm to help.
- Your arm will need to be in a sling for 2 to 6 weeks with no active movement and 3 months before strengthening. It will be around 4 to 6 months of recovery.
- Follow any instructions you are given about how to care for your shoulder at home. This includes activities that you should not do.

Outlook (Prognosis)
Shoulder replacement surgery relieves pain and stiffness for most people. You should be able to resume your normal daily activities without much problem. Many people are able to return to sports such as golf, swimming, gardening, bowling, and others.
Your new shoulder joint will last longer if less stress is placed on it. With normal use, a new shoulder joint can last for at least 10 years.
