Is a Total Shoulder Replacement Right for me?

Each year, approximately 50,000 people in the United States undergo shoulder replacement surgery. Total shoulder replacement is also referred to as shoulder arthroplasty: This procedure involves using artificial devices to replace damaged bones and arthritic joint surfaces. It is crucial that individuals who are considering shoulder arthroplasty choose an experienced and skilled Board Certified Orthopedic Surgeon like Dr. Christopher O’Grady.

The Anatomy of the Shoulder

Due to the shoulder’s extraordinary range of motion, it is an amazing piece of the human body. The shoulder’s incredible range stems from its internal construction. The shoulder consists of the clavicle (collarbone), scapula (shoulder blade) and the humerus (upper arm bone). All three of these bones join to form the shoulder joint. The humeral head (upper arm bone) fits perfectly into the socket of the glenoid (scapula bone), once these two bones are joined, this part of the shoulder is commonly referred to as the ‘ball-and-socket’ joint. The ball-and-socket joint allows the shoulder’s wide-ranging motion. The cartilage in the shoulder is essentially a smooth cushion that allows for easy and painless movement of the shoulder.

Degeneration Can Lead to Chronic Pain

As time passes, the ball-and-socket joint degenerates. This degeneration frequently occurs due to arthritis or a shoulder fracture, both of which cause the smooth surfaces of the cartilage to become rough. The bones in the shoulder begin to rub against one another, resulting in pain. In the event that conservative treatments fail, Dr. O’Grady may recommend surgical intervention as a means to reduce the patient’s pain and restore or improve his/her range of motion.

Common Causes of Chronic Pain

Degenerative Joint Disease (Osteoarthritis)

Osteoarthritis is a ‘wear and tear’ kind of arthritis that typically occurs in individuals who are 50 years or older; however, on occasion, osteoarthritis has occurred in those younger than 50 years of age. This condition causes the cartilage to soften and wear away, which leads to stiffness and pain in the shoulder joint as the bones begin rubbing against each other. Unfortunately, osteoarthritis cannot be prevented.

Rotator Cuff Tear Arthropathy

An individual who has a large, long-standing tear in the rotator cuff may develop the condition cuff tear arthropathy. With this condition, changes in the shoulder joint (caused by the rotator cuff tear) can lead to destruction of the cartilage in the joint and arthritis.

Post-Traumatic Arthritis

This condition can occur following a serious injury to the shoulder, such as tears in the ligaments or tendons of the shoulder that may damage articular cartilage or fractures of the bones making up the shoulder. Post-traumatic arthritis causes pain in the shoulder as well as limited mobility.

Rheumatoid Arthritis

This disease affects the synovial membrane surrounding joints. When an individual has rheumatoid arthritis, the synovial membrane inflames and thickens. This chronic inflammation eventually causes loss of cartilage as well as stiffness and pain.

Severe Shoulder Fractures

A severe shoulder fracture is another reason people choose to have a total shoulder replacement. If the head of the shoulder’s upper arm bone is shattered, Dr. O’Grady may find it extremely difficult to put these pieces back in place. Furthermore, the blood supply to these pieces may be interrupted. In a case such as this, Dr. O’Grady will most likely recommend that the patient has shoulder replacement surgery.

Osteonecrosis (Avascular Necrosis)

Osteonecrosis is a condition that occurs when the blood supply to the bone is interrupted. The loss of blood supply causes bone cells to die, this condition can eventually cause deterioration of the shoulder joint, eventually leading to arthritis. Some of the risk factors associated with avascular necrosis include sickle cell disease, deep sea diving, chronic steroid use, heavy alcohol consumption and a severe fracture of the shoulder.

Failed Shoulder Replacement Surgery

While a failed shoulder replacement is uncommon, some replacements do fail. Usually, failure occurs due to dislocation, infection, wear and tear or loosening of the implant. If this happens, a revision surgery may be necessary.

Who Benefits from Total Shoulder Replacement Surgery?

You may benefit from surgery if you have:

  • moderate/severe shoulder pain while resting making it difficult to have a good night’s sleep;
  • weakness in the shoulder and/or a decreased range of motion;
  • severe pain and stiffness interfering with daily activities (i.e., dressing, washing, reaching, toileting, etc.);
  • continued pain following more conservative treatment methods including physical therapy, cortisone injections and/or anti-inflammatory medications;
  • osteoarthritis, avascular necrosis, rheumatoid arthritis or a failed total shoulder replacement surgery;
  • severely damaged tissues or a severe fracture;
  • a tumor in or around the shoulder; and/or
  • chronic shoulder pain.
