Nerve injuries compromise the sensation and/or motor function provided by that specific nerve. Classically, this occurs by sharp laceration. However, it can also happen following blunt trauma, bites, gunshot wounds, and iatrogenic injury. Depending on the severity of the injury, varying degrees of nerve disruption can occur. Initially, recognition of the injury is key. This is typically done via history and physical examination. Defining the injury is crucial in understanding the location and extent of the problem. This becomes even more important with higher energy or more blunt injuries, when there is increased likelihood that the zone of injury Is extensive.
