Epidemiology Acute cervical trauma

Acute cervical trauma   
Incidence: The incidence of cervical spine injury in the setting of head injury has been reported to range between 1.8-9%4,7-9,14,15,18,25.Hu et al. reported the incidence in 1996 of spine fractures, all sites, to be 64/100,00016. However, subgrouping into cervical, thoracic or lumbar fractures was performed for only 45% of the patiënts. The assumed incidence of CS-fx can be estimated to be 12/100,000 based on this study, which was performed on a population in Canada.
Prevalence 71% of all C-spine injury patients were male, 22% were elderly (aged 65+years), 54% were injured in a transport crash, 33% were injured in a fall, 20% received in-hospital rehabilitation post-acute care (increasing to 58% for cord injuries) and 6% died during their acute hospital admission.2
Sex: Cervical spine fractures are more common in males than females1-4,6,10,11,13,17-21,26
Age: With respect to age, the highest incidence rate is reported to be among patients aged 15-45 years, with a second peak in those aged 65-80 years1-4,6-17,21-24.Median age 47.2 years (interquartile range, 29.8-66.0)26

age ≥35 years are at increased risk26

History of injury: Cervical spine injuries result primarily from motor vehicle accidents, falls, sports activities (e.g., rugby, American football, trampolining), and diving into shallow water. Patients with a lowered GCS or systolic blood pressure, severe facial fractures, dangerous injury mechanism. Contrary to common belief, head injury was not predictive for cervical spine involvement.26

    If a positive finding in any of the 5 points is there an indication for radiography.
The function of the spinal segments related to cervical spine
Physical Examination Physical presentation
Cervical Cervical (neck) injuries usually result in full or partial tetraplegia (Quadriplegia). However, depending on the specific location and severity of trauma, limited function may be retained.Injuries at the C-1/C-2 levels will often result in loss of breathing, necessitating mechanical ventilators or phrenic nerve pacing.
C3 vertebrae and above  Typically results in loss of diaphragm function, necessitating the use of a ventilator for breathing.
C4 Results in significant loss of function at the biceps and shoulders.
C5 Results in potential loss of function at the shoulders and biceps, and complete loss of function at the wrists and hands.
C6 Results in limited wrist control, and complete loss of hand function.
C7 and T1  Results in lack of dexterity in the hands and fingers, but allows for limited use of arms.

Study (instab/dysf.) Sensitivity (Show) Specificity (exclude) QUADAS Score 0-14
Stiell et al.1 99 45 12
Bandiera et al.2 100 43 9
Comment: Since the test is designed as a screening test, the sensitivity is very high. The test is negative if only all 5 points are negative. The rules are designed for patiënts in the acute phase.
