Thumb Arthritis — Why Everyday Tasks Hurt
Thumb arthritis is wear and tear of the cartilage in the joint at the base of your thumb. This joint is called the carpometacarpal (CMC) joint. When the smooth cartilage that cushions the joint wears away, the bones rub together, causing pain, swelling, and loss of motion.

Frequently Asked Questions
What causes thumb arthritis?
Thumb arthritis (CMC arthritis) is caused by wear and tear of the cartilage in the base of the thumb joint. It's more common in women over 40 and can be aggravated by repetitive gripping and pinching activities.
Why does thumb arthritis make everyday tasks so difficult?
The thumb CMC joint is crucial for gripping and pinching. When arthritis develops, simple tasks like opening jars, turning keys, buttoning clothes, or writing become painful because these activities all require thumb strength and stability.
Can thumb arthritis be treated without surgery?
Yes, many cases respond well to conservative treatment including splinting, anti-inflammatory medications, activity modification, and cortisone injections. Surgery is typically considered when these methods no longer provide adequate relief.
How successful is thumb arthritis surgery?
Thumb arthritis surgery has a high success rate, with most patients experiencing significant pain relief and improved function. Recovery typically takes 2-3 months, and most patients can return to normal activities with minimal restrictions.
