Odontoid process fracture, also known as a peg or dens fracture, occurs where there is a fracture through the odontoid process of C2.
Pathology
The mechanism of injury is variable, and can occur both during flexion or extension, and with or without compression .
Classification
There are two classification systems
- Anderson and D'Alonzo
- most commonly used
- describes level of fracture line (i.e. through tip, base, or lateral masses)
- Roy-Camille classification
- has been shown to better correlate with prognosis
- describes plane of fracture and displacement
Differential diagnosis
- os odontoideum
- persistent ossiculum terminale
- Mach effect
- dens agenesis
- hypoplasia of the odontoid process
