Trigger Finger

What is Trigger Finger?

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. Also known as stenosing tenosynovitis, trigger finger 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.

Symptoms

Diagnosis

Diagnosis typically involves: • Physical examination to check for tenderness, smoothness of motion, and locking • Discussion of symptoms and when they occur • Observation of hand while making a fist • Checking for pain when pressure is applied to palm • Usually no imaging tests needed • Assessment of which fingers are affected (often ring finger or thumb)

Treatment

Treatment options progress from conservative to surgical: • Rest and activity modification • Finger exercises and stretching • Splinting to keep finger extended • NSAIDs to reduce inflammation • Corticosteroid injections into tendon sheath • Percutaneous release (needle procedure) • Surgery to release the constricted tendon sheath • Physical therapy after surgery
