title: Emergency evaluation, imaging, and classification of thoracolumbar injuries.
abstract: Thoracolumbar injuries usually are the result of high-energy trauma and frequently are associated with multisystem concomitant injuries. Whenever a thoracolumbar injury is suspected, a prompt and thorough evaluation should be performed in the emergency department, using the guidelines of the American College of Surgeons and including full primary and secondary surveys as well as resuscitation. Protection of the spine and spinal cord is of paramount importance during the initial evaluation. A careful and complete neurologic examination is warranted as part of the secondary survey. Plain radiography, CT, and MRI studies are useful in diagnosing and classifying thoracolumbar injuries. At many trauma centers, CT has become the standard imaging technology for the initial evaluation of the spine. MRI is particularly accurate in detecting injury to the posterior ligamentous complex of the thoracolumbar spine. Classification and treatment of thoracolumbar injuries are controversial. The comprehensive, reproducible classification system of the Spine Trauma Study Group has prognostic significance and can guide treatment decisions. The Thoracolumbar Injury Classification and Severity scale classifies thoracolumbar injures based on three pivotal characteristics: the morphology of the injury, the integrity of the posterior ligamentous complex, and the patient's neurologic status. A total severity score is used in conjunction with the classification system to determine the treatment.
