The procedure is performed under general anesthesia with an axillary block. The anesthesiologist will discuss the block with you. It is accomplished by injected medicine in your axilla (armpit) while you are still awake. This allows you to wake up from surgery in no pain. The block will last for several hours after surgery. The surgery is performed by making an incision along the border of the thumb. The joint is removed (an entire bone is taken out) and replaced with a tendon graft. The tendon is obtained by making one or two incisions along your forearm. This is a tendon that is redundant and you will not notice its absence. One or two pins are used to stabilize the thumb. These pins will be removed in 4 weeks in the office.
