Abstract

Percutaneous trigger release is recognized as an effective minimally invasive procedure with a low complication rate. One prerequisite for percutaneous trigger release is a trigger of Quinnell Type II or higher; that is, a digit that is actively triggering. We describe an additional step in percutaneous trigger release, which enables the surgeon to perform the procedure in digits that are not actively triggering at the point of surgery. This step involves the infiltration of normal saline into the tendon substance distal to the A1 pulley in order to induce triggering.
