Trigger Finger

Trigger finger, medically known as stenosing tenosynovitis, is a condition in which a finger catches, clicks, or locks in a bent position when you try to straighten it. It occurs when inflammation narrows the space within the tendon sheath surrounding the flexor tendon, causing the tendon to catch as it passes through the pulley system.

Causes and Risk Factors

Trigger finger develops when the flexor tendon or its sheath becomes inflamed and thickened, creating a nodule that catches on the A1 pulley at the base of the finger. Repetitive gripping activities, diabetes, rheumatoid arthritis, gout, and hypothyroidism are known risk factors.

It is more common in women and in individuals between ages 40–60. The ring finger and thumb are most frequently affected, though any finger can be involved.

Treatment

Mild trigger finger may respond to splinting the finger in extension, activity modification, and anti-inflammatory medications. Corticosteroid injection into the tendon sheath is the most effective non-surgical treatment, with high success rates for early-stage disease.

When injections fail or the finger is locked, surgical trigger finger release is a quick outpatient procedure. Dr. Kinchelow releases the A1 pulley through a small incision at the base of the finger, allowing the tendon to glide freely. Recovery is rapid, with most patients resuming normal activities within days to weeks.
