Translation-rotation spine injuries are severe injuries characterized by horizontal displacement or rotation of one vertebral body with respect to another.
On this page:
These injuries result from torsional and shear forces. This type of injury is usually severe and involves the posterior ligamentous complex (PLC).
Translation-rotation spine injuries are characterized by:
- unilateral or bilateral perched or dislocated facet joints
- vertebral body subluxation/translation or rotation. Translational injury is best seen on lateral radiographs or sagittal CT or MR images, while the mediolateral instability is best seen on coronal images.
- posterior ligamentous complex injuries:
- splaying of the spinous processes with widening of the interspinous space
- avulsion fractures of the superior or inferior aspects of contiguous spinous processes
- common additional findings include transverse process and rib fractures
Using the thoracolumbar injury classification and severity score (TLICS), results in 3 points for the morphology and 3 points for the PLC, making a total of 6 points, which indicates a need for surgical stabilization.
