Arthritis in the thumb is the most common form of arthritis affecting the hands.
The pain caused by arthritis in the thumb can make simple tasks like opening a jar very difficult.
A combination of hand exercises and various medications can help relieve symptoms
Osteoarthritis in the thumb is the most common form of arthritis that affects the hands. Osteoarthritis results from the breakdown of joint cartilage and the underlying bone. It can affect the basal joint, which is the joint near the wrist and the fleshy part of the thumb. This joint normally allows you to pinch, pivot, and swivel your thumb for hundreds of tasks every day.
In people with thumb arthritis, the cushion-like cartilage inside the joint breaks down over time. This causes the bone to rub against bone. Symptoms of thumb arthritis can become crippling, partly because the thumb is needed so often each day. Decreased grip strength, decreased range of motion, and swelling and pain throughout your hand may occur. You may find it difficult to open jars, twist open a doorknob, or even snap your fingers.
If you have arthritis in other joints like your knees, hips, or elbows, it may make thumb arthritis more likely. Women are more prone to thumb arthritis, especially those with very flexible or lax thumb ligaments. Statistically, women are six times more likely than men to develop thumb arthritis.
