Method for treatment of trigger finger

摘要

Trigger finger release surgery is performed percutaneously using an instrument, having a prong with a blade about 3 to 7 mm from the distal end of said prong. The prong is inserted into the flexor tendon such that the blade is positioned adjacent the flexor sheath. Flexion or extension of the afflicted finger moves the flexor tendon along with the inserted instrument along the length of the sheath causing the blade to cut the sheath and release the tendon. The movement of the tendon safely directs the knife through the pulley sheath.
