- head rotated at time of collision
- previous cervical spine trauma or surgery

Diagnostic investigations
1st investigations to order
- multidetector computed tomography (MDCT) axial CT cervical spine with 3D reconstructions
Investigations to consider
- cervical spine x-ray series
- MRI cervical spine
- CT myelogram
- CT angiography (CTA) and MR angiography (MRA)
- flexion-extension (F/E) cervical spine x-rays
- nerve conduction studies
- electromyography
Treatment algorithm
acute neck pain with altered neurological status: at initial presentation
low probability of neurological injury: following initial assessment
high probability of neurological injury: following initial assessment
