title: Postpartum neuralgic amyotrophy with involvement of the anterior interosseous nerve.
abstract: Neuralgic amyotrophy (NA) is a syndrome of unknown etiology associated with pain in the necl" and shoulder girdle followed by wasting and weakness in muscles supplied by the brachial plexus. Electromyographic studies typically show evidence of denervation in affected muscles. In this report, two cases of NA, both of which presented in the postpartum period, ace described. Both of the described cases demonstrated severe involvement of the anterior interosseous nerve. The course and electrophysiological assessment of postpartum NA is discussed.
