Figure. A, Initial radiography showing the lateral view of the cervical spine. No significant injuries are depicted, but the lowest cervical vertebra is not seen. B, The repetition of the radiography including the whole cervical spine disclosed a fracture dislocation C6 to C7 injury. C, Magnetic resonance image (sagittal view) showing a dislocation of the C6 vertebral soma anterior to the C7 vertebra, associated to a bilateral fracture of the pedicles of C6 and the posterior elements. The medullary cord is significantly displaced but shows no signs of injury. D, Computerized tomography (axial view) showing a significant anterior displacement of the vertebral soma as well as a fracture dislocation with involvement of both the vertebral pedicles and the laminae, which determined a widening of the medullary canal.
