Advanced trauma life support radiographic trauma series: part 1--The cervical spine radiograph.

Plain cervical spine radiographs are the first line investigation in trauma patients to exclude cervical spine fractures and dislocations. Adequate views are essential to reduce the risk of missing diagnoses. Injuries may however not be visible on plain cervical spine radiographs despite adequate views. Additional imaging such as computer tomography scanning is indicated in the event of a normal plain radiograph if there is any clinical suspicion of injury.
