Question

Answer
was changed:
Chance fractures extend all the way through the spinal column (involve all three spinal columns): from posterior to anterior through the spinous process, pedicles, and vertebral body, respectively. Burst fractures usually do not involve the posterior elements.
Chance fractures tend to occur from a flexion-distraction type injury, whereas burst occur from axial loading forces.
The middle and posterior columns are typically disrupted, as opposed to a burst fracture, which is usually the anterior and middle columns.
