Arthritis of the Base of the Thumb

July 12, 2016

 

Do you have pain at the base of your thumb?

 

In the normal joints of your body, cartilage covers the end of the bones serving as a shock absorber to allow smooth, pain-free movement. In osteoarthritis (OA) or “degenerative arthritis,” the cartilage layer wears out. This results in direct contact between bones, producing pain and deformity.   One of the most common joints to develop OA in the hand is the base of the thumb. 

 

The most common symptom of OA is pain at the base of the thumb. This pain can intensify by activities that require pinching, such as opening jars, turning door knobs or keys, and writing. Depending on the severity, pain can also appear at rest or at night.

 

In more severe cases, a bump may develop at the base of your thumb as the metacarpal moves out of the saddle joint. The shift in the joint can cause limited motion and weakness, making pinching difficult. The joint above may compensate by loosening, causing it to bend further back.  This is known as hyperextension.
