Figure 2. (a) Sagittal plain radiograph of the cervical spine. There is an acute kyphotic angulation at C6/7 and a fracture of C7 with anterior wedging due to collapse of the superior endplate. There is a separated bone fragment from the superior endplate of C7. The C6/7 disc space is widened posteriorly. No other fractures were demonstrated on plain film. (b) Sagittal multislice CT (MSCT) showing fractures demonstrated on the plain radiograph, but in addition there is a retropulsed fragment of the posterior superior part of C7 into the canal. (c) Axial MSCT image of the fractured C7 vertebra showing the retropulsed fragment posteriorly displaced into the canal. (d) Sagittal MSCT image showing fracture of the inferior facet of C6. This was not diagnosed on the plain film. (e) Coronal MSCT showing fractures of the uncovertebral processes of C7. (f) Coronal MSCT image showing additional burst fracture at C6 not demonstrated on the plain radiograph.
