- Nerve Injuries
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.
Treatment
Nerve repair focuses on restoring the flow and continuity of the nerve to allow transmission of nerve signals. Treatment options for nerve injuries can vary depending on the extent of the injury. Some nerve injuries may recover naturally, while others may benefit from surgical treatment. If there are minimal symptoms, non-operative treatment can be considered. However, if there is loss of sensation or motor function, surgery is often recommended. Surgical options include freeing the nerve from restrictive scar, repairing a severed nerve, reconstructing the nerve using donor nerves, and transferring expendable nerves to the injured nerves. Following surgery, physical therapy may be initiated to maintain the flexibility of the limb while the nerve recovers. Overall, recovery from nerve injuries can be prolonged and variable. While full recovery is possible, it is not guaranteed.
