[Fracture-separation of the articular process of the lower cervical spine. Its relation to fracture-dislocation in hyperextension].
The authors have seen 13 cases of fracture-separation of the articular processes in the lower cervical spine with horizontal facets. This type of lesion was caused by trauma in hyperextension, compression and rotation. The mechanism appears to be similar to that of dislocations in hyperextension. Four types are defined according to the displacement and the association of disc and ligamentous lesions. Most of the cases were unstable and had to be fixed surgically. Eleven cases were treated in this way, twice by a posterior approach, 6 times by an anterior approach and 3 times by a combined anterior and posterior approach.
