shoulder arthritis causes and treatment options

457b1f977532f971a268719b876f3af0While we generally think of arthritis as being associated with old age, shoulder arthritis is not uncommon among younger people as well. Any injury to the shoulder, such as a dislocation or a fracture, can eventually lead to shoulder arthritis.

The shoulder consists of two main joints. The first is the glenohumeral joint. This is a ball-and-socket joint in which the head of the upper arm (humerus) fits into the glenoid cavity of the scapula (shoulder blade). The second is the acromioclavicular. This joint is formed by the meeting of the collarbone (clavicle) with the top of the scapula (acromion).

Hyaline cartilage located on the ends of these bones generally allows for movement of the arm in the socket without friction, but a loss of cartilage here can cause the bones to rub against each other. Although not as common as arthritis in other parts of the body, shoulder arthritis can be extremely uncomfortable and debilitating. The principal symptom of shoulder arthritis is steadily worsening pain, especially when the arm is moved.  However, patients with this condition are also likely to experience considerable stiffness in the joint and weakness at the shoulder. Sleeping may become difficult as the condition worsens, especially on the most affected side.

Shoulder arthritis may be caused by any of the following:

  1. Osteoarthritis.  This is the degenerative wearing of cartilage, especially at the acromioclavicular joint.
  2. Loss of cartilage through acute traumatic injury to the shoulder, such as from a car accident, particularly when there has been a tear in the rotator cuff.
  3. Rheumatoid arthritis, an inflammatory autoimmune disease in which the body attacks its own cartilage.

Both osteo – and rheumatoid arthritis is more prevalent in older people (osteoarthritis, in particular, tends to occur in those over age 50).  It’s not surprising that the overall incidence of shoulder arthritis is increasing as the general population ages.

Initial management of shoulder arthritis is usually non-surgical. Possible treatment options include:

  • Soft Tissue therapist  care
  • Targeted exercise programs to increase shoulder mobility
  • Heat and ice treatment
  • Nutritional supplements such as glucosamine and chondroitin, both of which build cartilage and can slow joint degeneration
  • Rest and shoulder immobilization
  • Modifying shoulder movements to minimize irritation
  • Non-steroidal anti-inflammatory drugs (NSAIDs)
  • Corticosteroid injections and other medications may be used in the case of rheumatoid arthritis

The National Arthritis Foundation reports that regular soft tissue therapy care can help prevent the damage caused by arthritis. Massage can help reduce pain and restore movement and increase range of motion in the shoulder joint.

In severe cases, surgery for shoulder arthritis can help to reduce pain and improve motion if non-surgical treatments are no longer working. Glenohumeral surgery can consist of either replacing just the head of the humerus with a prosthesis (hemiarthroplasty) or replacing the entire joint (both the humeral head and glenoid cavity, a total shoulder arthroplasty).
