Overview
Klumpke's paralysis or Klumpke's palsy or Dejerine-Klumpke palsy is palsy of the brachial plexus.
A form of brachial plexus injury in which there is paralysis of the muscles of the forearm and hand due to a childbirth injury to the roots of eighth cervical C8 and first thoracic T1 nerves or the lower part of the brachial plexus, a network of spinal nerves that originates in the back of the neck, extends through the axilla (armpit), and gives rise to nerves to the upper limb.[1][2]
The risk is greater when the mother is small or when the infant is of large weight.
