In a Shoulder Replacement Surgery (also known as Hip Arthroplasty) the ends of the damaged upper arm or shoulder bone are replaced with artificial surfaces lined with plastic or metal. Shoulder joint components may or may not be cemented. This helps in relieving the pain in your shoulder joint and can improve mobility greatly.
When is shoulder replacement surgery recommended?
Shoulder replacement surgery is usually recommended only if other treatments, such as physiotherapy, exercising or medications are no longer able to help mobility or reduce pain. Some medical treatments for osteoarthritis that may be used prior to hip arthroplasty include:
- Anti-inflammatory medications
- Pain medications
- Limiting painful activities
- Assistive devices for walking (such as a cane)
- Physical therapy
- Cortisone injections into joint
- Viscosupplementation injections (to add lubrication into the joint to make joint movement less painful)
- Glucosamine and chondroitin sulphate
- Exercise and conditioning
People who have arthroplasty generally have substantial improvement in their joint pain, ability to perform activities, and quality of life, so these are important reasons for the procedure as well.
What are the risks of shoulder arthroplasty?
As with any surgical procedure, complications can occur. Some possible complications may include:
- Blood clots in the legs or lungs
- Loosening of prosthetic parts
- Nerves or blood vessels in the area of surgery may be injured, resulting in weakness or numbness. The joint pain may not be relieved by the surgery.
- Lack of good range of motion
There may be other risks depending on your specific medical condition. Be sure to discuss any concerns with your health care provider prior to the procedure.
How do I prepare for arthroplasty?
- Your health care provider will explain the procedure to you and offer you the chance to ask any questions that you might have about the procedure.
- You will be asked to sign a consent form that gives your permission to do the procedure. Read the form carefully and ask questions if something is not clear.
- In addition to a complete medical history, your health care provider may perform a complete physical exam to ensure you are in good health before undergoing the procedure. You may undergo blood tests or other diagnostic tests.
- Tell your health care provider if you are sensitive to or are allergic to any medications, latex, tape, and anesthetic agents (local and general).
- Tell your health care provider of all medications (prescribed and over-the-counter) and herbal supplements that you are taking.
- Tell your health care provider if you have a history of bleeding disorders or if you are taking any anticoagulant (blood-thinning) medications, aspirin, or other medications that affect blood clotting. It may be necessary for you to stop these medications prior to the procedure.
- If you are pregnant or suspect that you are pregnant, you should notify your health care provider.
- You will be asked to fast for 8 hours before the procedure, generally after midnight.
- You may receive a sedative prior to the procedure to help you relax.
- You may meet with a physical therapist prior to your surgery to discuss rehabilitation.
- Arrange for someone to help around the house for a week or two after you are discharged from the hospital.
- Based on your medical condition, your health care provider may request other specific preparation.
What happens during arthroplasty?
Arthroplasty requires a stay in a hospital. Procedures may vary depending on your condition and your doctor’s practices. Arthroplasty may be done while you are asleep under general anaesthesia, or while you are awake under localised anaesthesia. Your anesthesiologist will discuss this with you in advance. Generally, hip arthroplasty follows this process:
- You will be asked to remove clothing and will be given a gown to wear.
- An intravenous (IV) line may be started in your arm or hand.
- You will be positioned on the operating table in a manner that provides the best access to the joint being operated on.
- A urinary catheter may be inserted.
- If there is excessive hair at the surgical site, it may be shaved off.
- The anesthesiologist will continuously monitor your heart rate, blood pressure, breathing, and blood oxygen level during the surgery.
- The skin over the surgical site will be cleansed with an antiseptic solution.
- The doctor will make an incision in the area of the joint.
- The doctor will repair or remove the damaged parts of the joint.
- The incision will be closed with stitches or surgical staples.
- A sterile bandage or dressing will be applied.
- You will need to stay in the hospital for about 4-7 days. Therapy will begin 1 day after the surgery and would continue for months after your surgery.
How long will I be away for shoulder replacement surgery?
What happens after arthroplasty?
In the hospital
After the surgery, you will be taken to the recovery room for observation. Once your blood pressure, pulse, and breathing are stable and you are alert, you will be taken to your hospital room.
Arthroplasty usually requires an in-hospital stay of several days. It is important to begin moving the new joint after surgery. A physical therapist will meet with you soon after your surgery and plan an exercise rehabilitation program for you.
Your pain will be controlled with medication so that you can participate in the exercise.
You will be given an exercise plan to follow both in the hospital and after discharge. You will be discharged home or to a rehabilitation centre.
In either case, your health care provider will arrange for continuation of physical therapy until you regain muscle strength and a good range of motion.
Once you are home, it will be important to keep the surgical area clean and dry.
Your health care provider will give you specific bathing instructions. The stitches or surgical staples will be removed during a follow-up office visit.
Take a pain reliever for soreness as recommended by your health care provider. Aspirin or certain other pain medications may increase the chance of bleeding.
Be sure to take only recommended medications.
Notify your health care provider to report any of the following:
- Redness, swelling, bleeding, or other drainage from the incision site
- Increased pain around the incision site
- Numbness and/or tingling of the affected extremity
- You may resume your normal diet unless your health care provider advises you differently.
You should not drive until your healthcare provider tells you to. Other activity restrictions may apply.
Making certain modifications to your home may help you during your recovery.
These modifications include, but are not limited to, the following:
- Proper handrails along all stairs
- Safety handrails in the shower or bath
- Shower bench or chair
- Raised toilet seat
- Stable chair with firm seat cushion and firm back with two arms, which will allow your knees to be positioned lower than your hips
- Long-handled sponge and shower hose
- Dressing stick
- Sock aid
- Long-handled shoe horn
- Reaching stick to grab objects
- Firm pillows to raise the hips above the knees when sitting
- Removing loose carpets and electrical cords that may cause you to trip Your health care provider may give you additional or alternate instructions after the procedure, depending on your particular situation.
