We investigated the prognostic value of concurrent Horner syndrome for predicting spontaneous motor recovery in surgical decision making at 3 months with neonatal brachial plexus palsy. Medical records of 129 neonates with total-type brachial plexus palsy were reviewed, and clinical and follow-up data of patients with or without Horner syndrome were compared. Twenty-seven of 129 newborn babies with total-type palsy (21%) had concurrent Horner syndrome. Poor spontaneous motor recovery was observed in 21 (78%) neonates with concurrent Horner syndrome and in 84 (82%) without concurrent Horner syndrome. Concurrent Horner syndrome in neonates with brachial plexus palsy has no prognostic value in predicting poor spontaneous motor recovery of the brachial plexus in patients with total-type palsy.
Level of evidence: III.
