The outcome of primary brachial plexus reconstruction in extended Erb's obstetric palsy when only one root is available for intraplexus neurotization.

Background: A recent review by the International Federation of Societies for Surgery of the Hand showed no studies comparing the results of nerve grafting to distal nerve transfer for primary reconstruction of the brachial plexus in infants with obstetric brachial plexus palsy (OBBP). The aim of this retrospective study is to compare two surgical reconstructive strategies in primary reconstruction of the brachial plexus in extended Erb's obstetric palsy with double root avulsion: one with and one without distal nerve transfer for elbow flexion.

Methods: Two groups of infants with extended Erb's palsy and double root avulsion were included in the study.
