- Services and Treatments
- Total Shoulder Replacement Surgery
Shoulder replacement surgery is usually done when you have severe pain in the shoulder area, which limits your ability to move your arm.
Causes of shoulder pain include:
- Osteoarthritis
- Poor result from a previous shoulder surgery
- Rheumatoid arthritis
- Badly broken bone in the arm near the shoulder
- Badly damaged or torn tissues in the shoulder
- Tumor in or around the shoulder
Your doctor may not recommend this surgery if you have:
- History of infection, which can spread to the replaced joint
- Severe mental dysfunction
- Unhealthy skin around the shoulder area
- Very weak (rotator cuff) muscles around the shoulder that cannot be fixed during surgery
Shoulder replacement surgery
For total shoulder replacement, the round end of your arm bone will be replaced with an artificial stem that has a rounded metal head. The socket part (glenoid) of your shoulder blade will be replaced with a smooth plastic shell (lining) that will be held in place with a special cement. If only one of these two bones needs to be replaced, the surgery is called a partial shoulder replacement, or a hemiarthroplasty.
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)
- Cement the new metal head and stem into place
- 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
This surgery usually takes 1 – 3 hours.
After the Procedure
- You may stay in the hospital for 1 – 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 – 6 weeks with no active movement and 3 months before strengthening. It will be around 4 – 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.
- You will be given instructions on shoulder exercises to do at home. Follow these instructions exactly. Doing the exercises in a wrong way can injure your new shoulder.
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.
