Trigger finger, also known as “stenosing tenosynovitis,” is a painful condition that can cause any finger or thumb to catch or lock in a bent or straightened position. The problem arises from a constriction of the finger tendons as they pass through a series of tunnels, called pulleys, as they leave the palm and enter the finger.

Trigger finger may be associated with diabetes, rheumatism, or thyroid disorders, but is frequently due to overuse, repetitive activities or trauma to the hand. Fortunately, trigger finger or thumb can frequently be cured with a corticosteroid injection into the tendon sheath. Sometimes surgery is required to correct the problem.

If you are experiencing painful catching or locking of your fingers or thumb, please call Timothy B. Larson, MD at 940-299-HAND to schedule your consultation.
