CMC Joint (Thumb) Arthritis

What is CMC Joint (Thumb) Arthritis?

CMC joint arthritis refers to arthritis at the carpometacarpal (CMC) joint located at the base of the thumb. This joint allows the thumb to pivot and grip, which makes it highly active and prone to wear over time. CMC arthritis is especially common in people over age 40 and in individuals who use their hands repetitively for work or hobbies.

The condition can limit your ability to perform everyday tasks such as opening jars, gripping objects, or writing. 

Symptoms of CMC Joint Arthritis 

• Pain at the base of the thumb, especially with pinching or gripping
• Swelling or tenderness near the wrist
• A visible bump or enlargement at the base of the thumb
• Reduced strength when grasping objects
• Stiffness or limited range of thumb motion
