Basal Thumb Arthritis

Arthritis describes a loss of cartilage from a joint resulting in pain, stiffness and a loss of function. Arthritis involving the Carpometacarpal joint at the base of the thumb is a very common condition in women and occasionally in men.

Patients typically present with aching pain or discomfort at the base of the thumb and over the thumb muscles; they may find it difficult to pinch and grab objects, and tend to avoid use of the hand.
