During the procedure, typically performed under local anesthesia, the surgeon releases the tight A1 pulley, a fibrous band that is restricting the tendon. This is done either through a small incision in the palm (open surgery) or with a needle in a minimally invasive technique (percutaneous release). The release allows the tendon to glide freely, restoring normal movement to the finger.
Trigger finger release is an outpatient procedure with a high success rate, and most patients experience significant symptom relief and improved mobility within a few weeks of surgery.
