The basal joint is the joint at the base of the thumb also known as the CMC (carpometacarpal) joint. This is one of the most important joints in our body as it gives the ability for the thumb to oppose to the other digits. Some opposition is what separates us from the animals. Because it is such a movable joint is prone to develop osteoarthritis even in younger people.
In The News
Osteoarthritis, or degenerative joint disease, is one of the most common causes of pain. This condition is caused by the deterioration of the cartilage at the ends of your bones. As this hard, yet slippery, material wears away, the bone edges can be exposed and can rub against each other, causing swelling, fluid build up, loss of motion and pain. Osteoarthritis can affect all joints in the body, most commonly the hips, knees, shoulders, fingers and spine. Often described as the result of “wear and tear,” this painful grinding sensation may stop people from doing the activities they enjoy.
