Thumb arthritis, also called basal joint arthritis, occurs when the joint at your wrist and the base of your thumb — the basal, or carpometacarpal (CMC), joint — develops osteoarthritis.

Having thumb arthritis can cause debilitating hand pain, swelling, and decreased strength and range of motion, making it difficult to do simple household tasks, such as turn doorknobs and open jars.

Treatment for thumb arthritis may include self-care measures, splints, medication or corticosteroid injections. In severe cases, you may need surgery to treat thumb arthritis.
