  • Trophic changes: Long standing paralysis leads to dry scaly skin
  • Cutaneous anesthesia and analgesia in a narrow zone along the ulnar border of fore – arm & hand
  • Horner’s syndrome: Injury to sympathetic fibres to the head and neck that leave the spinal cord through nerve T1

  • Trophic changes:Long standing paralysis leads to dry a scaly skin
