The prognostic value of concurrent Horner's syndrome in total obstetric brachial plexus injury.

The prognostic value of concurrent Horner's syndrome in infants with total birth palsy was investigated. The records of 48 cases with total palsy were reviewed. Poor spontaneous return of the motor function of the limb was found for both with and without concurrent Horner's syndrome. Fisher's exact test (P=0.02) indicated that the presence of concurrent Horner's syndrome is a significant prognostic factor for poor spontaneous recovery of the limb.
