Transcript
We're going to make an incision through the crease at the base of the thumb. I'm going to spread the tissue, opening the fat, the retractors to pull the nerves and arteries to the side of the wound. And then carefully I'm going to lift up the first pulley, or it's called the A1 pulley or annular pulley, exposing the tendon, showing the tendon right here.
And then I'm going to snip the pulley lengthwise to release the constricted band. It's impeding the tendon from moving fully. Now I've completed the division of the pulley. I'm going to gently tug on the tendon, the flexor tendon to the thumb, and I'm going to pull this out of the thumb. It allows me to move the thumb and make sure there's no further snapping of the thumb. And it will also allow me to inspect the lower surface or the flexor pulley sheath that you're seeing there deep to the wound.
