There are many different types of spinal fractures: Compression, Burst, Flexion-distraction, and Fracture-dislocation. Each of these types of fractures are described. Other terms your doctor may use to describe a fracture include stable, unstable, minor, and/or major. Fracture–dislocation, a severe injury in which both fracture and dislocation take place simultaneously. Frequently, a loose piece of bone remains jammed between the ends of the dislocated bones and may have to be removed surgically before the dislocation can be reduced.
