Prognosis following neonatal brachial plexus palsy: An evidence-based review

Purpose The spontaneous recovery rate of neonatal brachial plexus palsy (NBPP) is often cited as 75–95%. However, recent reports have found the recovery rate to be much lower. The purpose of this study was to perform an evidence-based review aimed at summarizing the available English language inform...

Description
Summary:Purpose The spontaneous recovery rate of neonatal brachial plexus palsy (NBPP) is often cited as 75–95%. However, recent reports have found the recovery rate to be much lower. The purpose of this study was to perform an evidence-based review aimed at summarizing the available English language information regarding prognosis following NBPP based on the Narakas classification. Methods A Medline database search was performed to identify articles that focused on the natural history, outcome, prognosis, or conservative treatment of neonatal brachial plexus birth injury from 1966 to 2006. Twenty-four articles were identified. The articles were graded according to the Oxford Evidence Based Grading Scale and data regarding sample size, follow up, study purpose, Narakas grouping, Mallet scale, and recovery of function at 3 and 6 months were extracted. Of the 24 articles, 11 were included for review. Data analysis included odds ratios and percent recovery. Results Of the 11 studies, only one was given a grade of a Level I study, three were given a grade of Level II, and seven were given a grade of Level IV. Sixty-four percent of infants classified as Narakas I and II had spontaneous recovery of biceps function at 3 months of age and only 9% of the Narakas III and IV group had recovery. Sixty-five percent of the Narakas I and II group had complete recovery at 6 months of age and only 14% of the Narakas III and IV group had recovery. The odds of biceps recovery at 3 months of age for the Narakas I and II group was 19 times higher compared to the III and IV group. The odds of complete recovery were 11 times higher for the Narakas I and II group compared to the III and IV group. Conclusion The quality of the literature regarding the prognosis of neonatal brachial plexus injury is poor. Based on the Narakas classification, recovery better for NBPP classified as Narakas I and II.
