Cervical spine X-ray images of case 1. On the frontal view (left), dilation of the
left facet joint at the level of C5/6 and dislocation of the C5 vertebral body to
the right side were revealed. From the lateral view (right), interspinous dilation
was observed.

A lateral plain radiograph showed interspinous dilation (Figure 2).
Reconstructed computer tomography image of case 1 (coronal view). Dilation of the
C5/6 facet joint and fracture of right lateral mass of C6 were clearly revealed.

C5/6 and dislocation of the C5 vertebral body into the right side (Figure 4). CT showed fractures of the C6 vertebral body and lateral mass.
MR images of case 2 (left and right: sagittal view and axial view at the C5/6
level, respectively). Injury of the C5/6 intervertebral disk, tear of the anterior
longitudinal ligament, and injury of the posterior supporting structure were
revealed.

MRI revealed injury of the C5/6 intervertebral disk, protrusion into the vertebral canal, tear of the anterior longitudinal ligament and injury of the posterior supporting structure (Figure 5).
Post-operative cervical spine X-ray images of case 2. Anterior and posterior
fixation with autologous bone grafts were performed.
