What is shoulder replacement surgery?
Shoulder replacement surgery, or shoulder arthroplasty, is a procedure to replace damaged parts of the shoulder joint with artificial implants. It’s a highly effective way to relieve severe discomfort and stiffness caused by arthritis and improve mobility.
The shoulder’s main joint, called the ball-and-socket joint, works when the ball-shaped top of the upper arm bone fits into the socket in the shoulder blade. Smooth cartilage covers these surfaces to help them glide easily during movement.
If you are living with arthritis, this cartilage wears away and causes the bones to rub together, leading to discomfort, stiffness and further damage. Shoulder replacement surgery restores smooth, pain-free motion and helps you regain strength and function by replacing the damaged joint surfaces with artificial ones.
Types of shoulder replacements
Shoulder replacement surgery is becoming increasingly common, and orthopedic surgeons can perform several types of the procedure. Your orthopedic surgeon will determine which one is right for you based on your health, the extent of shoulder damage and other factors.
Types of shoulder replacements include:
-
Total shoulder replacement
Your surgeon replaces the damaged ball with an artificial stem attached to a metal head (ball), and replaces the damaged shoulder socket with a plastic prosthetic.
-
Partial shoulder replacement
This procedure replaces only the ball part of the joint. It can be a good option if the socket is still healthy.
-
Shoulder resurfacing
This involves replacing just the surface of the humeral head, preserving the bone.
-
Reverse total shoulder replacement
The metal ball and plastic socket are switched—with the ball attached to the shoulder bone and the socket to the humerus—allowing shoulder muscles, instead of your rotator cuff, to move your arm.
-
Shoulder revision surgery
Corrects issues from failed shoulder replacements, loose implants or infections. Baylor Scott & White has surgeons who specialize in these complex cases.
Why might I need shoulder replacement surgery?
Severe pain or weakness in your shoulder can affect your daily life and prevent you from doing many activities like dressing or reaching into a cabinet. If alternative treatments, such as medication, corticosteroid injections and physical therapy, are not effective, shoulder replacement surgery could be an option for you.
Shoulder replacement surgery is most recommended for people with severe pain from arthritis. As we age, the cartilage in the shoulder joint can wear down, causing the bones to rub against each other, leading to pain, stiffness and the growth of bone spurs. Osteoarthritis is the most common cause of shoulder pain and is usually seen in people over 50, although it can also affect younger people.
Other conditions can damage the shoulder joint, including:
- Osteonecrosis: This happens when the blood supply to the bone is interrupted, causing the bone to weaken and collapse, which can result in pain and loss of function in the joint.
- Posttraumatic arthritis: After a shoulder fracture or dislocation, the cartilage in the joint may be damaged, causing long-term pain and stiffness.
- Rheumatoid arthritis: This is an autoimmune condition where the body's immune system attacks the joint lining, causing inflammation and pain. Over time, this can severely affect the shoulder joint and its function.
- Rotator cuff tear arthropathy: A large, long-standing tear in the rotator cuff can lead to arthritis and damage the cartilage in the shoulder joint.
- Severe fractures: A severe break in the upper arm bone can be difficult to fix, especially if blood supply to the bone is interrupted. In these cases, a shoulder replacement may be needed.
- Failed shoulder replacement surgery: Although uncommon, some shoulder replacements can fail due to implant loosening, wear, infection or dislocation. In such cases, a second surgery, called revision surgery, may be required to fix or replace the implant.
Shoulder replacement surgery can help relieve pain, improve movement and restore the function of the shoulder, allowing you to return to everyday activities and enjoy a better quality of life.
How to prepare for shoulder replacement surgery
If you decide to have shoulder replacement surgery, your orthopedic surgeon may recommend a physical exam with your primary care doctor a few weeks before the procedure to ensure you're in good health for surgery and recovery. If you have any chronic conditions, such as heart or kidney disease, you might also need to see a specialist, like a cardiologist or a nephrologist, for further evaluation.
It's important to discuss all the medications you're taking with your surgeon. Some medications, such as aspirin, ibuprofen and naproxen, should be stopped two weeks before surgery to reduce the risk of bleeding. If you take blood thinners, your doctor will advise you when to stop them.
To make your recovery easier, it's a good idea to prepare your home ahead of time. After surgery, you may have trouble reaching high shelves, so move items you'll need to low shelves. You might also need help with tasks like dressing, bathing, cooking and laundry. If you don't have support at home or if you're concerned about recovery, a short stay in a rehabilitation facility may be needed until you're more independent.
The shoulder replacement procedure
Here’s what you can expect before, during and after shoulder replacement surgery.
-
Before the procedure
Make sure to follow your surgeon's instructions about bathing, eating and taking medications before your surgery. You may be asked to stop eating for up to 12 hours before your surgery to help ensure everything goes smoothly.
When you come to the hospital for your surgery, it’s best to wear loose, comfortable clothes and a button-front shirt. After the surgery, you will need to wear a sling to support your arm, and your arm will be limited in movement during your recovery.
Before the surgery, you will meet with your anesthesiologist and surgeon to discuss how the surgery will be done and what kind of anesthesia you’ll receive. There are different types of anesthesia, and the team will decide what’s best for you. With general anesthesia, you’ll be asleep throughout the surgery and won’t feel anything. If you have regional anesthesia, you may stay awake but won’t feel any pain in the area around your shoulder because it will be numb. Sometimes, a combination of both general and regional anesthesia may be used.
-
During the procedure
The steps of the surgery will depend on which procedure is being done. In general, your surgeon will have you in a semi-reclined position with your arm in a special device. Your surgeon will make an incision in your shoulder to access the joint, remove damaged bone and cartilage, and place the new, man-made implant before closing the incision with stitches or sutures.
The whole process usually takes about one to two hours.
Your surgeon may be able to perform your surgery using very small incisions, which may allow you to heal faster.
-
After the procedure
After your surgery, you'll be taken to the recovery area, where nurses will monitor you as you wake up from anesthesia. You'll have a dressing on your shoulder, and an X-ray will be taken to check your shoulder. You’ll stay in recovery for at least an hour, depending on how you’re feeling.
Once you're in your hospital room, the nurse will check your vital signs, dressing and arm movement. Your arm will be in a sling for the first 24 hours. Managing pain is important, so you may need some pain medication if the nerve block doesn’t fully control your discomfort.
You'll be encouraged to move around and wear loose clothing for comfort. You’ll be able to shower after 48 hours. A physical therapist will show you simple exercises to help your recovery, and following these exercises is key to a good outcome. In some cases, you may need physical therapy after you go home, which your surgeon will discuss with you.
Shoulder replacement recovery
Recovery from shoulder replacement surgery usually takes around eight weeks or longer, with full recovery sometimes taking several months.
On the day of surgery, you'll wake up with your arm in a sling. While you may experience some discomfort, the arthritis pain you had before the surgery will be gone.
Your doctor will take X-rays the day after surgery to ensure the implant is in the correct position. Physical therapy will begin soon after, and you will likely notice immediate improvement, such as reduced grinding in the shoulder. During the early recovery phase, your arm will be kept in a sling to help the tendons heal, but you can remove the sling for showering and doing instructed exercises to improve movement.
Returning to work will depend on how well your shoulder recovers. Typically, you can return to desk work within two to three weeks, but if your job involves heavy labor, you may need three or more months of recovery. How quickly you heal will also depend on the condition of your shoulder muscles and tendons before the surgery.
Remember, following your rehabilitation plan is key to getting the best results and regaining full function after shoulder replacement surgery.
What are the risks of shoulder replacement surgery?
As with any surgery, shoulder replacement comes with some risks. These may include:
Dislocation
The ball of the new joint may come out of the socket.
Fracture
The bones in your shoulder may break during or after the surgery.
Implant loosening
The parts of the shoulder replacement may loosen or wear down over time, possibly requiring another surgery.
Rotator cuff problems
The muscles and tendons around your shoulder might not work as well after surgery.
Nerve damage
Nerves in the area of surgery can sometimes be injured, which may cause numbness, weakness or pain.
Blood clots
Clots can form in your legs or arms after surgery and, if they move, can be dangerous.
Infection
Infections can occur at the incision site, which may need treatment.
Frequently asked questions
-
Can you go home right after shoulder replacement surgery?
Yes, it’s possible. Some shoulder replacement surgeries are outpatient, which means you can go home the same day. However, you may need to stay in the hospital for a few days.
-
How long is shoulder replacement surgery?
Shoulder replacement surgery usually takes one to three hours. The exact time depends on factors like your health and the complexity of the procedure. The surgery involves removing the damaged joint and replacing it with an artificial one and sometimes repairing any torn muscles or tendons.
-
Is there an alternative to shoulder replacement surgery?
Yes, there are options besides shoulder replacement surgery, such as rest, physical therapy, injections (like steroids or plasma-rich therapy), stem cell therapy, shoulder resurfacing and massage therapy. Your healthcare provider can help you decide which treatment is best based on your specific needs and condition.
-
How long does it take to recover from shoulder replacement?
Recovery from shoulder replacement surgery usually takes about six months to regain most function, with full recovery taking up to a year. You'll notice improvements in the first few months, and physical therapy will help you get the best results. Your recovery time may vary depending on your health and age.
-
How painful is a shoulder replacement?
After shoulder replacement surgery, you'll feel some pain, but it's usually less than the pain you had before. As you recover, the pain gets better, and most people can manage it with over-the-counter pain medicine like ibuprofen or acetaminophen once the initial healing period is over.
-
How long does a shoulder replacement last?
A shoulder replacement usually lasts 10 to 15 years, and reverse replacements may last 15 to 20 years. Factors like your age, activity level and how well you follow post-surgery care can affect how long the implant lasts. Regular check-ups help ensure everything is working well over time.
