Chronic type 2 odontoid fracture with atlantoaxial spondyloptosis in an adult: a case report and literature review.

ABSTRACT:

Background

Type 2 odontoid fractures may be associated with varying degrees of atlantoaxial dislocation (AAD). Atlantoaxial spondyloptosis (AAS) is a rare cervical injury with reported etiologies including congenital, trauma, and rheumatoid disease, defined as having the facets of the atlas fixed anteriorly to the facets of the axis. When associated with a type 2 odontoid fracture, there is complete translocation of the C1 arch and the fractured odontoid process complex, anteriorly to the C2 vertebral body, representing a severe form of fixed or irreducible anterior AAD. The challenging anatomy increases the complexity of surgical decision-making, while the paucity of reported cases increases the challenge in deriving guidance to inform the surgical approach.
