The reported frequency of missed injuries in the cervical spine varies from 4% to 30%. Despite this surprising number of clinically minor injuries, the cervical spine remains the most common level for spinal cord injury (SCI), representing 55% of all SCIs. 4 One-third of the injuries identified in this study were considered clinically insignificant. Mechanism of injury in odontoid fracture trial#In another study, which is the largest multi-center trial to date, the most common site of injury was the atlantoaxial region, with the most commonly injured levels in the subaxial cervical spine being C6 and C7. The most common mechanism of injury was noted to be accidental falls, with motor vehicle/transport injuries being the second most common. 3 The annual incidence rate was 64/100,000 with two peaks, one in the second and third decade of the male population and another in elderly females. reported on patients in the Manitoba Health Insurance Plan from 1981–1984. 2 To date, only one population-based study of spinal column injuries has been performed in a complete population. 1 Certain demographic factors are known to be associated with blunt cervical spine injury: age greater than 65 years, male sex and white ethnicity. It has been reported that the cervical spine is injured in 2.4% of blunt trauma victims. ![]()
