Shoulder arthritis is one of the three types or arthritis that may affect the glenohumeral joint of the shoulder. In common with other types of arthritis, this condition is characterized by damaged or worn out cartilage connecting the bones of the joint. The main symptom is pain caused by the grinding of the bones against each other due to the lack of healthy cartilage between them. Shoulder supports and other orthopedic braces can provide pain relief and promote healing by restricting the movement of the bones or other joint structures relative to each other. Please consult with your doctor before deciding on a support or other medical device that is suited to your medical condition.
