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
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.
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.
Post Operative Care
Risk and Complications
- 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
