Basal Joint Arthritis
The basal joint - the joint at the base of the thumb - is a common site for osteoarthritis. The degeneration of the cartilage and/or joint is usually the result of wear and tear from overuse or from normal aging, but may also occur because of trauma.
Basal joint arthritis can be quite painful, cause weakness to the hands and restrict normal movement and the ability to pinch and grasp some objects. It typically occurs after the age of 40, is more common in women than men, and often affects both thumbs. As it progresses, the smooth surface of the joint may degenerate, resulting in prominent bony spurs.
This condition can grow worse by doing such repeated motions as: gripping objects with the thumb and fingers, twisting, or turning. The pain and tenderness from inflammation of the joint often increases during activities requiring pinching and grasping; it may cause as it progresses, the joint becomes more and more sensitive to pain, often leading those dealing with it avoiding activities using their thumbs. This, in turn, results in weakness and loss of muscle tone, making it difficult to hold even lightweight objects, pour milk, and perform common daily tasks.
If you are experiencing any of these symptoms, see a Health Care Professional for a proper diagnosis. Treatment of the early stages of basal joint arthritis often includes the use of an expertly dispensed splint for the wrist and/or thumb to protect and rest the thumb during some activities. As with other instances of arthritis, keeping the joint warm may also be helpful.
