Trigger Finger

A condition known as trigger finger occurs when one of your fingers becomes caught in a bent posture. With a snap, your finger may bend or straighten, similar to a trigger being pulled and released.

Stenosing tenosynovitis is another name for trigger finger (stuh-NO-sing ten-o-sin-o-VIE-tis). It happens when the area within the sheath that surrounds the injured finger's tendon narrows due to inflammation. Your finger may become trapped in a bent posture if your trigger finger is severe.

People with repetitive gripping activities in their jobs or hobbies are more likely to acquire trigger fingers. Women and people with diabetes are more likely to get the illness. The degree of trigger finger affects the treatment.
