This patient had a crushing injury to the fingertip with a laceration to the skin, disruption of the nail, and laceration of the nailbed. Repair of the nail was performed with local anesthesia numbing medicine and a finger tourniquet to minimize bleeding. The nail was replaced at the end of the procedure. The nail typically falls off after a week or two, and a new nail regrows. Regrowth of the nail is shown over the course of several months in the picture below.
