Nerve Injury

There are several types of nerve injuries that differ in level of severity; neurapraxia, axonotemis and neurotmesis.

Patients with the least severe form of nerve injury, neurapraxia, typically see a complete recovery. The actual structure of the nerve remains intact and usually involves compression of the nerve or disruption to the blood supply.

Axonotmesis is usually the result of a more severe crush, but can also occur when the nerve is stretched too far as a result of a severe injury. Regeneration of the nerves can occur over weeks to years.

Neurotmesis is the most severe lesion with the least potential of recovering. It occurs on severe contusion, stretch or laceration. The nerve and the connective tissue lose their continuity. This type of nerve damage causes an internal disruption of the architecture of the nerve. There is a complete loss of motor, sensory and autonomic function.

Symptoms

  • Temporary loss of function
  • Cause paralysis of the motor, sensory, and autonomic
  • Complete loss of motor, sensory and autonomic function

Treatment
The Department of Neurological Surgery provides care for patients who have had recent injuries that involve any aspect of the peripheral nervous system. Neuroradialogists assist in every patient diagnosis. Options for treatment include non-invasive surgical procedures.
