Living with Klumpke-Déjerine paralysis

A birth injury to the nerves at the shoulder that weakens the lower arm and hand.

Understanding Klumpke-Déjerine paralysis

Klumpke-Dejerine paralysis is a rare birth injury to the brachial plexus, the nerves around a newborn's shoulder, that affects the lower arm and hand.

It causes weakness and loss of movement in the lower arm and hand. Some babies also have a drooping eyelid on the same side of the face, called Horner syndrome. It is diagnosed at birth by physical exam, and sometimes X-rays and other tests show how much nerve damage there is. Most infants have the milder stretch injury and often recover within 6 months. Some need surgery, and rarely there is some permanent damage.

Signs & symptoms

Symptoms vary from baby to baby. GARD says these may occur:

  • Weakness of the lower arm and hand
  • Loss of movement in the lower arm and hand
  • Drooping eyelid (Horner syndrome)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
