加拿大颈椎规则（摄片/解除固定）

适用于钝性外伤后清醒、生命体征稳定的成人（原始验证情境）。

High-risk factors

If any high-risk factor is present, the rule indicates imaging (teaching).

Age 65 years or older Dangerous mechanism (fall from elevation, axial load to head, high-speed MVC, rollover or ejection, bicycle collision, motorized recreational vehicle) Paresthesias in extremities

Low-risk factors for safe assessment (all must be true to “clear” without imaging in the rule’s low-risk limb)

Only answer this section if no high-risk factors are present.

Simple rear-end motor vehicle collision (excluded if pushed into oncoming traffic, rollover, high speed, truck/bus, or commercial vehicle) Sitting position in ED Ambulatory at any time since injury Delayed onset of neck pain (not immediate) Absence of midline cervical spine tenderness Able to actively rotate neck 45° left and right (pain-free rotation teaching endpoint)
