Example of a translation injury (C2). Code: T12/L1–C2 (L1–A4) [upper row translational injury as seen on an AP radiograph of a T12/L1 subtype C2 with L1 subtype A4 injury (left). Coronal (middle) and axial (right) CT cuts show marked set-off of the lateral vertebral body walls and a burst fracture with a large retropulsed bony posterior wall fragment into the spinal canal causing significant spinal canal encroachment at the L1 level, lower row corresponding sagittal CT reconstructions at the left facet joint (left), mid-sagittal (middle), and right facet joint (right). Failure of the anterior as well as posterior column with bilateral facet fractures]
