Unstable (usually)
Mechanism: axial loading with flexion compromising anterior and middle column
Retropulsion of bone causes damage to the spinal canal and neurologic deficits that often cause stable neurologic deterioration.
Can occur with or without injury to posterior elements (posterior involvement increases risk for neuro deficits)
