Early Surgical Intervention in Amniotic Band Sequence for Upper Extremity Motor Nerve Palsies: A Case Report.

Urgent surgical intervention for amniotic band sequence (ABS) is currently indicated for concerns of vascular compromise and progressive lymphedema. Peripheral motor nerve palsies are rare, and reports of surgical intervention in these cases describe persistent motor dysfunction. We report band release and ulnar, median, and radial nerve decompression in a 1-week-old with a severe upper extremity constriction band and signs of ulnar nerve motor dysfunction. A literature review on nerve exploration and outcomes of patients with motor nerve palsy from ABS was performed. Early evidence of ulnar motor function was observed at 5.5-month follow-up. Previous reports of nerve decompression for upper extremity constriction bands with motor nerve palsy document poor recovery after interventions beginning at 3 months of age. In this case, band release and nerve decompression were undertaken at 7 days of age, and we observed early motor recovery. This finding suggests that very early surgical intervention in the neonate may facilitate nerve recovery in appropriate candidates.
