The cross-table lateral view is essential in the initial workup of a trauma patient with a suspected cervical-spine injury. The identification of the radiographic "ring" of C2 on the cross-table lateral view is discussed. When a type III odontoid fracture is present, the ring of C2 is disrupted. We propose that "identification of the ring of C2" should be added to the emergency physicians' systematic checklist when clearing a cross-table lateral view of the cervical spine.
在对疑似颈椎损伤的创伤患者进行初步检查时，颈椎侧位片至关重要。本文讨论了在颈椎侧位片上识别C2的影像学“环”。当存在III型齿状突骨折时，C2的环会中断。我们建议，在对颈椎侧位片进行评估时，“识别C2的环”应添加到急诊医生的系统检查清单中。
