    Abstract:
    Birth-related brachial plexus injury occurs in 0.19-2.5 per 1,000 live births, of which 70-92% improve with conservative management. With the advent of microsurgical techniques, patients who fail expectant treatment may benefit from brachial plexus exploration and reconstruction. From 1991 to 1996, 87 patients were referred to the multidisciplinary brachial plexus clinic at St. Louis Children's Hospital. Twenty patients were selected for surgical management. The average age at surgery was 10.5 months (range 3-35, median = 8), with an average follow-up of 23.9 months (range 7-45, median = 24). Two patients were lost to follow-up. Surgical procedures included neurolysis (n = 8), neurotization (n = 2), nerve grafting (n = 5), and a combination (n = 3) of the above. Two patients underwent exploration without repair. Intercostal nerves, pectoral nerves, and C4 roots were used for neurotizations, and the sural nerve was used for nerve grafting. Results from 18 patients were available for follow-up review. Fifteen patients (83% demonstrated clinical improvement postoperatively. Of the 3 patients without improvement, 2 underwent exploration without repair, and one underwent neurolysis of the axillary nerve. Of patients undergoing reconstruction, 93% had improved strength postoperatively. No subjects had worsening neurologic status, and there were no complications. These results suggest that surgery for birth-related brachial plexus injury may show favorable outcomes if patients are selected appropriately. Patients undergoing neurolysis and nerve grafting had more favorable outcomes than those undergoing neurotization.
