A burst fracture is a type of compression fracture where the vertebral body is severely compressed from a high magnitude axial load caused by the intervertebral disk being forced into the inferior aspect of the vertebral body above. This results in a comminuted fracture of the vertebral body where fragments of the fracture may be retropulsed into the spinal canal, potentially compromising the spinal cord (Figure 12.4).

Pathologic vertebral fractures due to metastasis can occur under normal physiologic activities (Taneichi et al. 1997). Failure of the spine’s load-bearing capacity from metastatic disease can lead to both pain and neurologic deficit (Hipp et al. 1995). Taneichi et al. (1997) determined that about 35–50% destruction of thoracic and lumbar vertebrae by a tumor would pose a clinically significant risk of collapse. On the other hand, a tumor with a volume of 24% of the whole vertebra has also been found to be a lower threshold for burst fracture (Tokuhashi et al. 2005). While lesion volume evaluations are useful, they are limited in their clinical validity as the measurement of tumor size is difficult and time-consuming (Hardisty et al. 2007).
