Erb's Palsy: Brachial Plexus Paralysis

Erb's Palsy is mainly caused by birth trauma when traction of the head or arm, or twisting the arm or shoulder down and backward, results in paralysis of the nerves supplying the arm. There are three main types of paralysis:

  • Erb's Palsy is a paralysis of the shoulder and elbow, involving the 5th and 6th cervical nerves. This manifests itself with the arm being turned towards the body, the elbow unable to bend and the hand being in the 'waiters tip' position.
  • Klumpke's Paralysis involves the 7th and 8th cervical and 1st thoracic nerves. The result is a flaccid paralysis of the hand which is often associated with Horner syndrome - drooping of the eyelid, the cheek does not sweat and the pupil may be smaller than the unaffected side.
  • Complete paralysis of the arm occurs when all the above five nerves are affected. The entire arm is paralysed and there is demonstrable sensory loss. Horner syndrome is often present as is Torticollis.

The incidence of Erb's Palsy is now established at 1 in 2,000 live births. It is now possible to say that over half of children born with Erb's Palsy make a complete recovery and another thirty to thirty-five per cent make very useful recovery as relates to nerve injuries, but that between twenty-five to thirty per cent of the children face difficulties due to contracture at the shoulder leading to posterior dislocation of that joint. Properly conducted neurophysiological investigations are most helpful in determining the likelihood of recovery. The indication for an urgent operation can be restricted to a relatively small number of children who have complete and severe injuries or those who have suffered major injury to the plexus from breech delivery.
