Facet dislocation refers to anterior displacement of one vertebral body on another. Without a fracture, the only way anterior displacement can occur is by dislocation of the facets.

Facet dislocation can occur to varying degrees:

The injury usually results from forced flexion of the cervical spine. However, where there is a degree of rotation, the facet dislocation may only occur to one facet joint:

bilateral facet dislocation ~~- unstable~~: unstable
unilateral facet dislocation ~~- stable~~: stable
