The National Emergency X-Radiography Utilization Study (NEXUS) and the Canadian Cervical Rule (CCR) have established criteria developed by physicians establishing when a patient needs cervical neck imaging radiographs to safely avoid over use in appropriate patients:
- Is there any high-risk factor that mandates radiography? *
- Is there any low-risk factor that allows safe assessment of range of motion?
- Can the patient actively rotate his or her neck 45° right and left?
My patient (above) was involved in a traumatic bicycle sports accident*. Even though he could rotate 45 degrees it was guarded rotation and with “dangerous mechanism”.
