    CT scan is important in cervical spinal cord injury because plain radiographs may miss as much as a third of cases of additional damage.

    A new study indicats that it is important to get CT scans in cases of cervical spinal cord injury because a third of patients may be sustaining secondary injury to parts of the spinal cord that was not diagnosed by plain radiography.

    UCLA Study Helps ER Physicians Identify Previously Undetectable Spinal Injuries

    A new national study indicates that patients with a cervical spinal injury (CSI) may harbor additional spinal damage not visible on regular x-rays. In fact, more than a third of patients who were thought to have low-risk injuries actually have additional damage that may include significant fractures with the potential to produce serious spinal problems if not detected and treated properly.

    This study will be published as an early online release in the Annals of Emergency Medicine, stands in the face of previous medical thinking in which patients with certain forms of spinal injury were considered at very low risk of having additional injuries. Because of that low risk, physicians were urged to use plain x-rays and avoid computed tomography (CT) in evaluating these cases.

    "These findings are significant because they suggest that CT imaging, which allows physicians to view the spine in much greater detail, is necessary in evaluating all patients who have radiographic evidence of cervical spine injuries," said lead study author Dr. William Mower, professor of emergency medicine at the David Geffen School of Medicine at UCLA. "We found that even among patients with low-risk injuries, more than one third sustained secondary damage that was not diagnosed by plain radiography."

    Mower adds that approximately one-fourth of these secondary injuries occurred in another part of the cervical spine, which suggests that at least some of these patients may have actually sustained two separate spinal injuries.

    Researchers reviewed patient cases from the National Emergency X-Radiography Utilization Study (NEXUS), which was conducted at 21 centers across the United States.
