Traumatic atlantoaxial dislocation without associated odontoid fracture or neurologic deficit is rare. We present the case of a 39-year-old male pedestrian who was struck by a vehicle and sustained a traumatic grade 4 C1-2 retrolisthesis. Closed reduction was successful, and the patient underwent posterior occipitocervical fusion. His neurologic status was good throughout the hospital stay, and he was discharged to a rehabilitation facility with full strength.
