Prospective study comparing outcomes of primary intraplexal repair versus distal nerve transfers in Narakas grade I birth brachial plexus palsy.

To compare the results of intraplexal repair and distal nerve transfer in babies with birth brachial plexus palsy (BBPP), children with Narakas group I obstetric palsy were assigned to two groups of 16 each. Children in group A were treated with classical intraplexal repair and those in group B were treated by distal nerve transfers. At 6 months, all the children in group B had achieved Modified Medical Research Council (MMRC) grade 3 elbow flexion along with 8 of the 16 children in group A, which was a statistically significant difference. At 6 months, all the children in group B achieved MMRC grade 3 or higher shoulder abduction and 8 of the 16 children in group A had done so, which was also statistically significant. At the final follow-up, the distal transfer surgical treatment group had a significantly higher Mallet score. Distal nerve transfers have a significant advantage in early recovery in elbow flexion and shoulder abduction, but the outcomes became similar after 9 months.Level of evidence: III.
