Evidence of the Effectiveness of Primary Brachial Plexus Surgery in Infants With Obstetric Brachial Plexus Palsy-Revisited.

A recent systematic review questioned the effectiveness of primary surgery in infants with obstetric brachial plexus palsy. At our center, the indication for primary surgery in infants with upper Erb's obstetric palsy is the lack of active elbow flexion at age 4 months. The current study compares the outcome of motor recovery in 2 groups of infants with upper Erb's palsy: one group (n = 9) treated surgically between age 4 and 5 months, and another group (n = 9) treated conservatively despite the lack of active elbow flexion at age 4 months. The only reason for not doing the surgery in the latter group was refusal by the parents. The scores of motor recovery were collected at the 2-year follow-up visit, and they were significantly better in the surgical group. The study demonstrates the effectiveness of primary surgery in infants with upper Erb's obstetric palsy compared to conservative management.
