Surgery removes some of the palmar fascia. This can take a few hours. You may be awake, but drowsy, during surgery. Or, you may have general anesthesia (where you “sleep”). Your healthcare provider may use a zigzag-shaped incision to reach the fascia. A zigzag allows better healing and finger motion. When surgery is complete, part of your incision may be left open to help drainage. As you heal, it will close on its own. A thick bandage or cast will be placed over your hand and forearm. You most likely will go home the day of surgery.
