Original ArticleTorticollis Associated With Neonatal Brachial Plexus Palsy

We investigate the incidence of torticollis associated with neonatal brachial plexus palsy, whether the severity of brachial plexus palsy affects outcomes and the rate of recovery. We performed a retrospective review of 128 consecutive neonatal brachial plexus palsy patients evaluated at the University of Michigan from 2005-2009. Patients were followed for at least 3 months, with regular physical examinations and imaging. Forty-three percent presented concurrently with torticollis. Significant differences were evident in mean age at first brachial plexus examination, suggesting that patients with concurrent torticollis present earlier for clinical examination. Recovery from torticollis was evident in 62% of patients by 23 ± 12 weeks with conservative management. No statistically significant differences were evident between torticollis and nontorticollis groups after reviewing their severity of neonatal brachial plexus palsy (Narakas score), recovery from neonatal brachial plexus palsy (biceps function at 6 months), need for nerve repair or reconstructive procedures, or infant, maternal, or other factors associated with labor. Results suggest that although torticollis occurs with increased frequency in children with brachial plexus palsy, its presence is not related to severity and does not affect the probability of recovery from brachial plexus palsy. Conservative management for torticollis yields reasonable recovery.
