Burst fractures are a type of compression fracture related to high-energy axial loading spinal trauma that results in disruption of a vertebral body endplate and the posterior vertebral body cortex. Retropulsion of posterior cortex fragments into the spinal canal is frequently included in the definition. However, some authors, including the popular AO spine classification system, define a burst fracture as any axial compression fracture involving an endplate and the posterior cortex regardless of retropulsion 6.

They usually present as back pain and or lower limbs neurologic deficits in the clinical scenario of trauma.

Burst fractures most commonly occur at L1 with the majority (~90%) occurring from T9-L5. Two-level burst fractures are much less common than single-level burst fractures 2. Burst fractures involve the posterior wall of the vertebral body can be described as incomplete (o...
