Purpose

The Canadian C-Spine Rule (CCR)[1] is a decision making tool used to determine when radiography should be utilized in patients following trauma.

Population

The Canadian C-Spine Rule is applicable to patients who are in an alert (Glasgow Coma Scale score of 15) and stable condition following trauma where cervical spine injury is a concern.

It is not applicable in non-trauma cases, if the patient has unstable vital signs, acute paralysis, known vertebral disease or previous history of Cervical Spine surgery and age <16 years. 

The Rule

Canadian C-Spine Rule

Evidence

Sn= 99.4 Sp=45.1 [2] 

Negative Likelihood Ratio associated with this highly sensitive test is less than 5%.  This means there is only a 5% chance that if you get a negative finding for this test, the patient would still have the condition.
