Cervical Spine Dislocation.

This is a Sagittal MRI of a facet dislocation of C-7 on T1. Cervical fractures and/or dislocations occur when injuries applied to the cervical spine are greater than the strength of the vertebral bodies or the the supporting ligaments. Subluxation or dislocation occur when there is a disruption in the posterior soft tissue supporting ligaments. These can occur with or without neurologic injury, depending on the extent . Sometimes the initial diagnosis is made by plain radiographs of the lateral c-spine in flexion and extension. This should only be done in the presence of a spine surgeon and in a patient who is awake.
