title: Split atlas in a patient with odontoid fracture.
abstract: We report the unusual association of a split atlas and an odontoid fracture in a case of a cervical trauma, thus mimicking a complex C1-C2 fracture. The normal embryology of C1 and the literature on this rare malformation are reviewed.
