klumpke's paralysis
Klumpke paralysis is a type of brachial palsy in newborns. Signs and symptoms include weakness and loss of movement of the arm and hand. Some babies experience drooping of the eyelid on the opposite side of the face as well. This symptom may also be referred to as Horner syndrome. Klumpke paralysis is caused by an injury to the nerves of the brachial plexus which may result from a difficult delivery. This injury can cause a stretching (neuropraxia), tearing (called avulsion when the tear is at the spine, and rupture when it is not), or scarring (neuroma) of the brachial plexus nerves. Most infants with Klumpke paralysis have the more mild form of injury (neuropraxia) and often recover within 6 months.
