CTICasesFlexion-Distraction Thoracic Spine Injury
Imaging findings
Chest radiograph shows mediastinal and left paraspinal widening. CT confirms a flexion-distraction injury of the thoracic spine (T-spine fracture-dislocation) with vertebral body compression, rupture of the posterior longitudinal ligament and facet joints, and canal narrowing.
Key takeaways
Flexion-distraction spinal injuries result from severe hyperflexion forces and are highly associated with mediastinal/paraspinal hematomas (which mimic aortic injury on radiographs) and spinal cord deficits.
