Demonstration of the clinical picture and the operative findings in the left hand.. A) Preoperative appearance of the left hand. Note the locked Grade III triggering of the middle and ring fingers. There was also Grade II triggering of the index and little fingers.. B) Following the release of pulleys, a large fibrous nodule was seen within the substance of the flexor tendon (at the tip of the mosquito). Note that the senior author uses a single transverse incision across the distal palm to obtain exposure to flexor tendons of adjacent fingers.. C) Postoperative views showing full flexion and extension of the fingers without pain or locking.
