==Background==
[[File:Three-column-concept-2.jpg|thumb]]
Denis' three column concept helps to determine whether a vertebral fracture is stable or unstable
*I: Anterior column
**Anterior longitudinal ligament
**Anterior 1/2 of the vertebral body and disk
*II: Middle column
**Posterior 1/2 of the vertebral body and disk
**Posterior longitudinal ligament
*III: Posterior column
**Facet joints
**Ligament flavum
**Posterior elements

==Clinical Features==
*I:Always stable
*II:Possibly unstable
*III:Always unstable

==Example of Unstable Fractures==
*[[Jefferson's fracture]]
*Bilateral [[Cervical facet dislocation]]
*[[Odontoid fracture]], type II or III
*[[Atlanto-occipital dissociation]]
*[[Hangman's fracture]]
*[[Flexion teardrop]]
*''Mnemonic: "Jefferson Bit Off A Hangman's Thumb"''

==Workup==
*CT with reconstructions
*Consider plain x-ray in conjunction as this is what is used during orthospine f/u
*MRI to assess cord and ligament damage

==Management==
{{Unstable cervical spine fracture management}}
