Let's Talk about Arthritis of the Thumb

Thumb base arthritis, also known as basal joint arthritis or carpometacarpal (CMC) joint arthritis, is a condition characterized by the inflammation and degeneration of the joint at the base of the thumb. This joint, located at the junction of the thumb and the wrist, is crucial for the thumb's range of motion and function. Thumb base arthritis is a common condition, especially in older adults, and it can significantly impact daily activities that involve fine motor skills and grasping.

Causes: Thumb base arthritis is often associated with wear and tear on the joint over time. Factors contributing to the development of this condition may include:

1. Age: The risk of thumb base arthritis increases with age.

2. Gender: Women are more commonly affected, possibly due to hormonal factors.

3. Genetics: There may be a genetic predisposition to developing arthritis.

4. Trauma: Previous injuries or trauma to the thumb joint can increase the likelihood of arthritis.

5. Joint laxity: Looseness or instability in the joint can contribute to its degeneration.
   

Symptoms: Common symptoms of thumb base arthritis include:

1. Pain: Pain at the base of the thumb, especially during gripping or pinching activities.

2. Swelling: Swelling and tenderness around the base of the thumb.

3. Stiffness: Reduced range of motion, particularly in activities that involve opposition and rotation of the thumb.

4. Weakness: Weakness in the thumb, making it challenging to perform tasks that require a strong grip.

5. Deformity: Over time, the joint may become enlarged, and a noticeable bump may develop at the base of the thumb.
