The joint at the base of the thumb which allows for the swivel and pivoting motions of the thumb is referred to as the basal joint or thumb CMC (carpometacarpal) joint. Because of its design, it tends to wear out and develop arthritis early in life. Basal joint arthritis is also common in people who have osteoarthritis.
