Evaluating the Cervical Spine in the Blunt Trauma Patient.

Following a blunt trauma, the goal of the cervical spine evaluation is to identify any injuries that might require active management: either through continued use of a collar or surgical stabilization. This is achieved through a step-wise approach that considers the nature of the patient's trauma, presenting complaints, distracting injuries and capacity to cooperate with the examination. In the last 15 to 20 years, technological advances in radiographic imaging have improved clinicians' abilities to certify the cervical spine as free of injury following blunt trauma. Within the last decade, the use of CT has supplanted plain radiograph imaging as the standard screening modality. Although MRI is more sensitive than CT in identifying occult cervical injury, particularly ligamentous or soft-tissue trauma, the standard addition of MRI to CT evaluation alone does not significantly increase the detection of clinically important cervical injuries.
