Osteoarthritis is a breakdown of cartilage in the joints. Cartilage is the protective coating on the ends of bones where they form a joint. When cartilage wears down, the bones grind against one another. This causes pain, stiffness and swelling.
Shoulder arthritis makes it difficult to do simple things like buckle a seat belt or get dressed. It can also keep you from sleeping well. Causes of shoulder arthritis include aging, repetitive overhead movements, injuries and infection.
Treatments include medication, cortisone shots and wearing a splint or brace. Exercise and modifying daily activities can also help. If these don’t work, surgery may be needed.
