Background: This study correlated the extent of spinal canal compression from retropulsed traumatic burst cervical, thoracic, and lumbar spine fractures with the severity of neurological dysfunction. Methods: One hundred and sixty-nine patients with cervical, thoracic, or lumbar sub-axial traumatic burst fractures were seen in an emergency department from 2019 to 2021; 79.3% were men, averaging 37 years of age. The lumbar spine was most frequently involved (42%), followed by the thoracic (36.1%) and cervical (21.9%) levels. The extent of spinal canal compression was quantitated utilizing Hashimoto’s method, and correlated with patients’ extent of neurological injury based on their American Spinal Injury Association scores. Results: There was a positive correlation between the extent of cervical and thoracic spinal cord compression due to retro pulsed burst fragments and the severity of the patients’ neurological deficits, but this was not true for the lumbar spine. Conclusion: The extent of spinal cord compression from retropulsed cervical and thoracic traumatic burst fractures was readily correlated with the severity of patients’ neurological dysfunction. However, there was no such correlation between the extent of cauda equina compression from retropulsed lumbar burst fractures and the severity of their cauda equina syndromes.
