Thumb Arthritis

The carpometacarpal joint (CMCJ) is at the base of the thumb. It gives us the ability to pinch, and pick things up in our hand because it positions the thumb against the fingers. Due to the saddle type design of the joint, frequent use, and the ageing process, this joint is prone to develop arthritis. Osteoarthritis of the base of the thumb (CMCJ OA) often results in joint degeneration, pain, impairment of joint movement and a reduced ability to use the hand to perform the regular activities of daily life.

Hand therapy and splinting is the mainstay in the conservative management of arthritis in the base of the thumb. Surgical treatments are also available when conservative treatment does not adequately resolve a patient's symptoms

What to expect at your initial hand therapy appointment for thumb arthritis:

1. An accurate diagnosis of your condition.
An accurate diagnosis is the basis for successful treatment of your symptoms. There are a variety of conditions which can occur at the base of the thumb, and these need to be considered prior to commencing treatment. Bring x rays to your first appointment if you have them.

You will be asked about your lifestyle, occupation and recreations. Specifically those which are causing difficulty.
