What id Thumb OA?

Arthritis at the base of the thumb is a type of osteoarthritis, a condition in which cartilage breaks down and releases substances that cause joint inflammation and pain.

Thumb arthritis is typically found at the carpometacarpal (CMC) joint located at the base of the thumb. The CMC joint allows the thumb to have a wide range of motion – up, down and across the palm – as well as the ability to pinch.

The most common symptoms of thumb CMC arthritis are swelling, stiffness and pain. These symptoms can be aggravated by activities that require pinching and may eventually worsen to the point of causing pain even when at rest. In severe cases, the destruction of the joint leads to malalignment, and a prominence develops at the base of the thumb as the thumb joint moves out of position. Malalignment can also lead to limited motion and weakness.
