Thumb carpometacarpal arthritis. Bakri K(1), Moran SL. Arthritis is a condition that irritates or destroys a joint. Although there are several types of arthritis, the one that most often affects the joint at the base of the thumb (the basal joint) is osteoarthritis (degenerative or "wear-and-tear" arthritis). CMC THUMB ARTHRITIS. Arthritis occurs when the cartilage – the flexible tissue that covers and protects the joints - wears out. Without this cushioning, the bones in the joint grind together wearing the joint down. Carpometacarpal (CMC) joint arthritis is arthritis at the base of your thumb, where your thumb and wrist meet. The carpometacarpal (CMC) joint is at the base of the thumb, where the thumb attaches to the hand. Like arthritis in the hip or knee, the pain comes when the cartilage wears away so much that bone rubs against bone. As with OA of the knee and hip, CMC OA is more common in women than men. By age 80, up to 80 percent of women are affected.
