Over the last 15 years, it was noted at our obstetric palsy clinic that good spontaneous recovery in newborns with extended Erb\u2019s palsy (C5, C6, C7 injury) was more likely if they recovered active wrist extension against gravity before 2 months of age. A hypothesis was made that newborns with extended Erb\u2019s palsy (Narakas Group II) may be subclassified into two groups according to this \u2018early recovery of wrist extension.\u2019 In a retrospective study of 581 cases with strict inclusion criteria, the hypothesis was found to be true: patients with extended Erb\u2019s and \u2018early recovery of wrist extension\u2019 have significantly higher percentages of good spontaneous recovery of limb function than those with extended Erb\u2019s and \u2018no early recovery of wrist extension\u2019 ( P&lt;0.0001 by chi-squared test).<\/jats:p>","DOI":"10.1177\/1753193409348185","type":"journal-article","created":{"date-parts":[[2009,9,28]],"date-time":"2009-09-28T20:18:56Z","timestamp":1254169136000},"page":"788-791","source":"Crossref","is-referenced-by-count":99,"title":["Narakas classification of obstetric brachial plexus palsy revisited"],"prefix":"10.1177","volume":"34","author":[{"given":"M.
