What is the difference between a Chance and a burst fracture?
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.
Acute L2 vertebral body fracture, with significant retropulsion, severely narrowing the central canal (absolute stenosis) and impinging on the conus/origin of the cauda equina.
Small superior posterior L3 vertebral body fracture.
