Abstract
The precise mechanism of odontoid fractures is unknown. However, the mechanism most likely includes a combination of flexion, extension, and rotation. The Anderson – D’Alonzo classification of acute odontoid fractures, which dates from 1974, describes three subtypes (Type I, II, III) based on the morphology of the fracture. A new subtype, Type IIA, was proposed by Hadley et al. in 1988.
