Condition 101

What is the definition of Trigger Thumb?

Trigger finger or thumb, also known as digital stenosing tenosynovitis, is a condition in which a finger or thumb is stuck in a position as if it were squeezing a trigger. When the thumb or finger straightens, it may do so with a snap, as if a trigger were being released. Trigger finger or thumb is caused by a narrowing of the sheath that surrounds a tendon due to inflammation, and often occurs from work that requires repetitive gripping motions. The condition is more common in women and people with diabetes, rheumatoid arthritis, or gout, or can also occur as a complication of carpal tunnel surgery.

What are the symptoms for Trigger Thumb?

Symptoms of trigger finger are a finger or thumb that locks in a bent position, with a painful snapping or popping when straightening or bending finger, a painful bump at the base of the finger or thumb, stiffness, and worsened symptoms in the morning or with a grasping motion.

What are the current treatments for Trigger Thumb?

Treatment for trigger finger or thumb can be conservative or require surgery. Conservative treatments focus on reducing swelling by allowing the tendon to rest, which may require wearing a splint or tape, applying ice and heat, and cortisone injections. If conservative treatments fail, then a surgical procedure known as trigger finger release may also be performed.
