case_images: Computed tomography from time of presentation. (a) Axial section at the T2-T3 level. The solid arrow points at the left T2-3 jumped facet showing the classic "empty facet sign" at the left facet joint. (b) Left paramedian sagittal section. The solid arrow shows the superior articulating facet of T3 situated superficial to the inferior articulating facet of T2, creating the "jumped" facet at T2-T3 and mild anterolisthesis.

case_images: T2 vertebral body, jumped left T2- T3 facet, T2-T3 vertebral distraction (i.e., Arbeitsgemeinschaft fur Osteosynthesefragen classification T2-T3C (T2: A1; N0), and Grade I anterolisthesis. The right facet was normal [Figure 1].
case_images: Magnetic resonance imaging from time of presentation. (a) Axial T2 section image at T2-T3 level. The solid arrow shows the significant edema around the left T2-3 facet joint, the disruption of the joint capsule, and the jumped facet on the left. (b) Mid sagittal short T1 inversion recovery image, showing no cord compression. The solid arrow points out the significant disruption of the ligamentum flavum and interspinous ligament and the associated vasogenic edema.

case_images: The magnetic resonance imaging (MRI) showed no significant cord compression or hematomyelia, but did identify soft- tissue edema in the anterior longitudinal ligament, posterior longitudinal ligament, ligamentum flavum, and interspinous ligaments at T2-T3 consistent with a 3-column injury [Figure 2].
