Hard cervical collar applied and an urgent computed tomographic (CT) scan of the cervical spine was performed in the emergency department demonstrated a C6C7 bilateral facet joint fracture dislocation with high-grade anterior spondylolisthesis/spondyloptosis of C6 vertebra over C7 vertebral body (Figure 1).
A lateral cervical (left) and transverse (right) T2 MRI scan demonstrating the injury. A large disk fragment can be seen posterior to C6 vertebral body with mild compression on the anterior cord.
