Pull-out Tenolysis Versus Simple A1 Pulley Release in Trigger Digits

A short transverse incision will be made over the proximal or distal palmar crease, according to the digit involved. Blunt dissection will be used to spread the subcutaneous tissue and the palmar fascia to expose the A1 pulley. The digital nerves and vessels will be retracted and protected. The proximal edge of the A1 pulley will be identified and a scalpel blade will be used to divide the entire A1 pulley under direct vision. Flexor digitorum superficialis and flexor digitorum profundus tendons or flexor pollicis longus tendon (for the thumb) will be gently pulled out of the wound with two mosquito forceps to break any adhesions. The wound will be closed primarily with sutures. The patient will be asked to actively move the digit to confirm complete relief of triggering.The wound will be closed primarily with sutures.
