Overview
Shoulder arthritis is a condition that causes pain, weakness and swelling in the shoulder joint. It occurs more commonly with advancing age, but younger people can develop arthritis after a shoulder injury, such as a fracture.
Types of Shoulder Arthritis
The two primary forms of shoulder arthritis are:
- Osteoarthritis—the most common form of arthritis, also known as “wear and tear” or degenerative arthritis. It causes a breakdown of the cartilage between each bone in the shoulder joint. When cartilage wears away, the bones start to grind against one another, causing pain, inflammation, and decreased movement.
- Rheumatoid arthritis—an autoimmune disease where the immune system attacks healthy parts of the body, especially the joints. In severe cases, it can cause joint deformities and organ problems.
