Thread Trigger Finger Release: Step-by-Step Procedure Animation
An animated, step-by-step look at Thread Trigger Finger Release: local anesthetic, ultrasound identifying the A1 pulley with the nerve and artery beside it, a thread passed beneath and then over the pulley, and the pulley divided. The A2 pulley is left intact. No incision, no stitches, two poke holes.
Transcript
A thread trigger finger release begins with local anaesthetic. Ultrasound finds the A1 pulley, and the nerve and artery beside it. A needle passes beneath the pulley, clear of both. A second pass over the pulley loops the thread around it. Pulling the ends divides the pulley. The A2 pulley is left intact. No incision. No stitches. Two poke holes.
