Percutaneous release of trigger digits - A technique and results using a specially designed knife

We describe a safe and easy percutaneous technique for release of trigger f inger using a specially designed knife. The Al pulley is sectioned by a bla de which has a hooked end. We released, percutaneously, 185 trigger fingers , including 62 which were locked using this technique. Satisfactory results were achieved in 173 (93.5%). There were no significant complications. We recommend this as a safe and effective outpatient procedure for those patie nts who have not responded successfully to conservative treatment, have lon gstanding symptoms or severe triggering.
