Radiology of thoracic and lumbar fractures.

High-resolution computed tomography (CT) is superior to other imaging modalities in assessing the extent and degree of spinal fractures. The determination of bone fragments within the spinal canal and the detection of posterior neural arch damage are major advantages offered by computed tomography. The addition of intrathecal contrast allows proper assessment of the oftentimes confusing neurologic picture. Plain roentgenograms of the spine are only the initial diagnostic examinations of spinal fractures. Roentgenograms in conjunction with high-resolution CT, performed with or without intrathecal contrast, provide the best evaluation of thoracolumbar spinal fractures.
