Objective:　To report a method and remote therape utic effect of early nerve transposition in treatment of obstetrical brachial pl exus palsy.rn　　Methods:　From May 1995 to August 1996, 12 patients who had no r ecovery of biceps 3 months after birth were treated with nerve transposition. Ei ght had neuroma at the upper trunk and 4 had rupture or avulsion of the upper tr unk. Mallet test was used to evaluate the results. rn　　Results:　The follow-up of 40-52 months showed that excellent and good recovery in functions was found in 75% of the patients and the excellen t rate of phrenic nerve and accessory nerve transposition was 83.3% and 6 6.7% respectively. A complete recovery in shoulder and elbow joint function wa s in 3 patients and Mallet Ⅳ was in 6 patients. rn　　Conclusions:　Satisfactory outcome can be obtained by using earl y nerve transposition in treating obstetrical brachial plexus.Paralysis, obstetric; Peripheral nerves; Nerve trans position
