Patients at risk for thoracolumbar junction (TLJ) and lumbar spine (LS) injury after blunt trauma are classically evaluated using conventional radiographs. Frequently, these patients also undergo abdominal and pelvic computed tomographic (CT) scanning to exclude the presence of associated intra-abdominal injuries. Standard abdominal and pelvic CT scan usually includes an anteroposterior (AP) scout film (scanogram) obtained before the cross-sectional imaging. The objective of this study was to determine whether a lateral CT scanogram and axial CT views would provide adequate imaging to allow for evaluation of the TLJ and LS and therefore eliminate the need for conventional screening computed lumbar spine radiographs (CLSRs). ⋯ Our CT + S protocol (axial CT images plus AP and lateral scanograms) outperformed screening CLSRs in the detection of fractures of the lower spine (TLJ + LS) after blunt trauma. In addition, scanogram imaging is less dependent on body habitus and adds no additional cost or time to abdominal and pelvic CT scanning. Further study is required to determine whether CT + S can routinely replace conventional radiographs of the lower spine after blunt trauma.

The purpose of this study was to better define the incidence and characteristics of patients with spinal cord injury without radiographic abnormality (SCIWORA), using the database of the National Emergency X-Radiography Utilization Study (NEXUS). ⋯ In the large NEXUS cohort, SCIWORA was an uncommon disorder, and occurred only in adults.
