The optimal method of clearing the cervical spine in obtunded trauma patients is unclear. Computed tomography (CT) identifies most injuries but may miss ligamentous injuries. Magnetic resonance (MR) imaging has been widely used to exclude ligamentous injuries. We postulate that with the new generation of CT scanners, MR imaging is not needed to rule out significant injuries. Our protocol for clearing the cervical spine in obtunded trauma patients depends on CT alone. We are prospectively following these patients and performing a clinical examination when they are awake to show this is a safe approach.
