Burst Fracture Definition. A burst fracture is a spinal injury where the vertebra breaks due to immediate and severe compression. Immediate trauma such as a car accident or a severe fall are the leading causes for burst fractures with pieces of the vertebra shattering into surrounding tissues and sometimes the spinal canal. This is different from a compression fracture in that the vertebra breaks in multiple directions.
