Atlantoaxial Instability in Neurofibromatosis Type 1: A Case Report

Journal of Orthopaedic Case Reports
Introduction: Neurofibromatosis (NF) is a cluster of conditions in which tumors grow in the nervous system. Even though the spine is the most common site of skeletal involvement in NF type 1 (NF-1), cervical spinal anomalies are infrequent.
