[Repair of the brachial plexus in the obstetrical lesions of the newborn].

Obstetrical lesions of the brachial plexus have not disappeared despite the major improvements of obstetrics. A large number of these babies will recover spontaneously but a minority will need a surgical repair. During the past 30 years, the author has repaired 932 brachial plexuses in newborns that had not recovered the biceps three months after the obstetrical injury. Some type of repair is always possible and the results are largely superior to those of spontaneous recovery. These results are presented with a follow-up of more than 20 years in some patients. They confirm the positive effect of early repair of the plexus.
