Peripheral nerve: trauma

Contributor(s): Steve Adair

Introduction

  • Injury to peripheral nerves is relatively common.
  • Neurapraxia = temporary or partial loss of function.
  • Neurotmesis = permanent loss of function.
  • The effect of loss of sensation and function is variable; for example:
  • Palmar digital neurectomy   Palmar digital nerve: neurectomy  results in loss of sensation to the palmar aspect of the foot, but causes little loss of function.
  • Facial nerve trauma   Facial nerve: trauma    →   distress and secondary signs.
  • Regeneration of peripheral nerves does occur at a rate of about 1 mm/day.
  • Damage to motor nerves easier to assess than damage to sensory nerves.
