What is shoulder arthritis?
Shoulder arthritis is a condition in which the cartilage that normally provides a smooth covering over the ball and socket is lost. This cartilage loss can result from degeneration wear and tear inflammatory disease (i.e. rheumatoid arthritis) injury or prior surgery.
Who usually gets shoulder arthritis?
What are the symptoms of shoulder arthritis?
Shoulder arthritis often leads to shoulder pain weakness stiffness of the joint bone spurs and loss of the normal shape of the bones. It may also grind and catch when the shoulder moves. When arthritis is advanced it may prevent work play activities of daily living and comfortable sleep.
The best test to show arthritis is a special set of x-rays. The x-ray to the right shows bone spurs and loss of the normal space between the ball (head of the humerus) and socket (glenoid). These are two findings that we look for that demonstrate arthritis in the shoulder.
Mild cases of arthritis of the shoulder can be treated anti-inflammatory medications and with gentle shoulder stretching exercises to maintain the range of motion.
When shoulder arthritis is advanced and does not respond to gentle exercises consideration is given to joint replacement surgery in which the joint surfaces are replaced such as with a ‘ream and run’ or a total shoulder arthroplasty may be considered. These procedures are usually very effective in reducing the symptoms of shoulder arthritis. Shoulder joint reconstruction can now be performed with minimal involvement of the deltoid and rotator cuff muscles. Ordinarily gentle and simple rehabilitative exercises are started immediately after surgery and are continued for a year to maximize the recovery of comport strength range of motion and function.
What are the risks with surgical treatment?
The risks of shoulder surgery include but are not limited to the following: infection injury to nerves and blood vessels fracture stiffness or instability of the joint loosening or wear of the artificial parts failure of the rotator cuff pain and the need for additional surgeries. There are also risks to anesthesia and blood transfusion (although transfusions are not always necessary). An experienced shoulder joint replacement team that does many such procedures each month will use special techniques to minimize these risks but cannot totally eliminate them.
Can patients regain all of their shoulder function and how long would it to fully recover after the surgery?
A shoulder replacement can never be as good as a normal shoulder. However in most cases a technically sound surgery coupled with a good rehabilitative effort on the part of the patient will lead to a major improvement in comfort and function. The first goal of rehabilitation is to restore range of motion. Once this is achieved the focus shifts to strength and endurance. While improvements may be evident soon after surgery gains in strength range and coordination may continue for up to a year after surgery.
The specific individual rehabilitation program after surgery can only be specified by the surgeon who performed the procedure in view of the specifics of the condition of the shoulder and the procedure performed. It is important that the repaired tendons are not challenged until they have had a chance to heal. Usually the patient is asked to lift nothing heavier than a cup of coffee for six weeks after the surgery; the use of the shoulder is increased progressively after that.
If I need surgery where should it be done; what is the effect of the surgeon's experience?
On one hand it seems convenient to have surgery done close to home. On the other hand recent published research has shown that “the patients of surgeons with higher average annual caseloads of total shoulder arthroplasties and hemiarthroplasties have decreased complication rates and hospital lengths of stay compared with the patients of surgeons who perform fewer of these procedures.” (you may wish to read this JBJS article). In this study the surgeons were categorized according to the number of procedures they performed: low-volume surgeons performed an average of 0.29 procedure per year whereas middle and high-volume surgeons performed an average of 1.6 and 7.54 procedures per year respectively. For perspective the surgical team at the University of Washington performs well over 200 shoulder replacement surgeries per year and has done so for the past two decades. Many of these patients have come from other western states – California Oregon Montana Alaska Idaho Wyoming – and some from the mid-west and the east coast.
