Bilateral facet dislocation

Last revised by Daniel J Bell on 6 May 2024

A bilateral facet dislocation is an unstable flexion distraction type of dislocation of the cervical spine, often a result of buckling force. Occasionally, the bilateral facet dislocation has been named a 'doubly-locked' vertebral injury giving the impression of stability. However, due to complete ligamentous disruption, this is, in fact, an unstable injury 1.



A bilateral facet dislocation was historically thought to result from hyperflexion, however, since 2010s it is thought that a buckling force is more likely to be the primary cause 2.
