KLUMPKE'S PARALYSIS

INTRODUCTION:
  • Klumpke's palsy or Dejerine–Klumpke palsy is a variety of partial palsy of the lower roots of the brachial plexus.
SITE OF INJURY:
  • Lower trunk of brachial plexus
ETIOLOGY:
  • Undue abduction of the arm, as in
  • Clutching something in hands while falling from a height
  • May be in birth injuries [forceful breech delivery]
AFFECTED ROOTS:
  • Mainly T1, Partly C8
MUSCLES PARALYZED:
  • Intrinsic muscles of the hand(T1)
  • Ulnar flexors of the wrist and fingers(C8)
CLINICAL FINDINGS:
  • Hyperextension at metacarpo - Phalangeal joint
  • Flexion at inter - Phalangeal joint"
  • "Claw Hand/'intrinsic minus HAND"
  • Cutaneous anesthesia and analgesia in a narrow zone along the ulnar border of fore - arm & hand
  • Vasomotor changes skin areas with sensory loss is warmer due to arteriolar dilatation
  • Trophic changes: Long standing paralysis leads to dry a 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
  • Vasomotor changes in skin areas with sensory loss is warmer & drier due to arteriolar dilatation
  • Trophic changes:Long standing paralysis leads to dry a scaly skin
Exam Question
  • Lower trunk of brachial plexus is the site of injury leading to brachial plexus
