These injuries occur when a nerve is cut, for example by glass or metal during a car accident, or by a knife during a stabbing. Generally, nerves injured in this manner are repaired by suturing the severed ends back together as soon as possible after the injury occurs. Delayed repair makes this surgery more difficult.

Occasionally, nerve lacerations can occur accidently during surgery. As with other nerve lacerations, these are best repaired by a peripheral nerve surgeon as soon as possible after they occur.
