title: Resolution of traumatic hypertrophic periodontoid cicatrix after posterior cervical fusion: case report.
abstract: The case of a 38-year-old man with delayed myelopathy 19 years after a nontreated odontoid type II fracture is reported. Magnetic resonance imaging of the craniocervical region revealed a periodontoid cicatrix. The clinical syndrome improved, and complete resolution of the retro-odontoid mass was achieved 9 months after posterior cervical fixation. The implications of this unique case for the management of myelopathy associated with nonunion of odontoid fractures are discussed.
