Shoulder Joint Replacement

The shoulder is a highly movable body joint that allows various movements of the arm. It is a ball and socket joint, where the head of the humerus (upper arm bone) articulates with the socket of the scapula (shoulder blade) called the glenoid. The two articulating surfaces of the bones are covered with cartilage, which prevents friction between the moving bones. The cartilage is lubricated by synovial fluid. Tendons and ligaments around the shoulder joint provide strength and stability to the joint.

When the cartilage is damaged, the two bones rub against each other resulting in pain, swelling and stiffness of the joint (osteoarthritis).

Total shoulder replacement surgery is performed to relieve these symptoms. In this surgery, the damaged articulating parts of the shoulder joint are removed and replaced with artificial prostheses.  Replacement of both the humeral head and the socket is called a total shoulder replacement.

Who is a Candidate for Shoulder Joint Replacement?

Total shoulder joint replacement surgery is indicated for conditions such as osteoarthritis or rheumatoid arthritis when medication, injections, physical therapy, and activity changes do not help relieve pain. Your doctor recommends surgery when you have the following symptoms:

  • Severe shoulder pain that restricts daily activities
  • Moderate to severe pain during rest
  • Weakness and/or loss of motion
Diagnosis

To decide whether total shoulder replacement is a good option for you the surgeon will evaluate your condition thoroughly.

Your surgeon reviews your medical history and performs a physical examination of your shoulder to assess the extent of mobility and pain. Imaging tests such as X-ray or MRI (magnetic resonance imaging) are ordered.

Replacement Options

Your surgeon will perform either a primary total shoulder replacement or a reversed total shoulder replacement. Both procedures replace the “total” shoulder joint, meaning implants replace both the “ball” and “socket” of the shoulder joint.

Patient Education Brochure

Primary Total Shoulder Replacement

The OrthoTeam uses the SIMPLICITI™ Shoulder System for total shoulder replacements. The The SIMPLICITI™ Shoulder System is a stemless device which is less invasive making surgical recovery less painful and quicker than traditional shoulder replacements.

Reversed Shoulder Replacement

Patients who have a torn rotator cuff and painful shoulder arthritis may benefit from a “reverse shoulder replacement.” The implant reverses the shoulders normal structure using the strength of the deltoid muscle to move the arm.

Procedure

With a CT image of the patient’s shoulder, our surgeons uses 3D computer technology to map out each patients surgery before the patient comes to the hospital. The surgery is done under general anesthesia. An incision is made over the affected shoulder and the underlying muscles are separated to expose the shoulder joint. The upper arm bone (humerus) is separated from the glenoid socket of the shoulder bone. The arthritic or damaged humeral head is cut and the humerus bone is hollowed out and filled with cement. A metal ball with a stem, is gently press fit into the humerus. Next, the arthritic part of the socket is prepared. The plastic glenoid component is fixed in the shoulder bone. After the artificial components are implanted, the joint capsule is stitched and the wound is closed.

Post Operative Care

After the surgery, pain medications and antibiotics are prescribed to control pain and prevent infection. Your arm may be secured in a sling or cast. The rehabilitation program includes physical therapy, which is started soon after the surgery and is very important to strengthen and provide mobility to the shoulder. You may be able to perform gentle daily activities two to six weeks after surgery.

Risk and Complications

As with any major surgery, there may be potential risks involved:

  • Anesthetic complications such as nausea, dizziness and vomiting
  • Infection of the wound
  • Dislocation, requiring repeat surgery
  • Damage to blood vessels, nerves or muscles
  • Failure to relieve pain
  • Pulmonary embolism
  • Wear and tear of prosthesis

Our focus is on returning you to your previous normal activity level, whether that be in a sporting activity, work situation or activities of daily living.
