Burst fractures are a type of compression fracture which results in disruption of the posterior vertebral body cortex with retropulsion into the spinal canal.When it involves the thoracolumbar level, it tends to occur between T9 and L5 level. Burst fractures may be stable or unstable.It is a result of a compressive high energy injury (axial loading), much like the Jefferson fracture. Typically it occurs following a fall, landing on the feet, from a significant height.urst fractures may be stable or unstable.
