Thumb arthritis

What is it?

Osteoarthritis at the base of the thumb (known as the CMC joint) is a common form of arthritis in the hand. This joint has a wide range of motion and is subject to repeated stress during hand function such as carrying and pinching. This stress can lead to degenerative changes to the cartilage creating direct contact between bones causing pain and possible deformity over time


 Pain is the main symptom usually felt as a sharp or aching pain at the base of the thumb, aggravated by activities such as opening jars, turning doorknobs and keys. Often pain is worse with movement and relieved by rest. Other symptoms include reduced strength and ability to grip or pinch and stiffness.

A hand therapist can provide exercises, advice on joint protection techniques and thumb supports and orthoses which can help manage your symptoms and slow progression of the condition.

If you are experiencing any of these symptoms, book an appointment.
