Thumb Locking Up | Carpal Tunnel Syndrome Forum | Conditions and Disease
Trigger finger is a condition in which one of your fingers gets stuck in a bent position. Your finger may bend or straighten with a snap — like a trigger being pulled and released. It occurs when inflammation narrows the space within the sheath that surrounds the tendon in the affected finger. If trigger finger is severe, your finger may become locked in a bent position. People whose work or hobbies require repetitive gripping actions are at higher risk of developing trigger finger. The condition is also more common in women and in anyone with diabetes.
Why Do the Joints in Your Fingers Lock Up?
When fingers or the thumb lock up while bent, the condition is known as trigger finger; causes of the condition include repeated or forceful movements, gout, diabetes and rheumatoid arthritis, notes WebMD. Holding something firmly in a set position for a long time also causes joints to lock up. Musicians, manufacturing workers and farmers often develop locked joints because they make the same thumb and finger movements over and over, explains WebMD. The repeated use of a lighter can cause trigger finger in smokers. Women are more likely than men to develop this condition, and the age group most at risk is between 40 and 60 years of age.
