NEXUS criteria
NEXUS (National Emergency X-Radiography Utilization Study) is a set of validated criteria used to decide which trauma patients do not require cervical spine imaging.
Trauma patients who do not require cervical spine imaging require all of the following:
alert and stable
no focal neurologic de...

Canadian C-spine rules
Canadian C-spine rules are a set of guidelines that help a clinician decide if cervical spine imaging is not appropriate for a trauma patient in the emergency department. The patient must be alert and stable.
There are three rules:
is there any high-risk factor present that requires cervical s...

Cervical spine alignment
When assessing cervical spine alignment, look for four parallel lines connecting structures in the cervical spine:
anterior vertebral line: anterior margin of the vertebral bodies
posterior vertebral line: posterior margin of the vertebral bodies (also known as George's line)

Article
Atlantoaxial fixation
Atlantoaxial fixation refers to various surgical techniques to stabilize the atlantoaxial complex.
History and etymology
The first effort of an atlantoaxial stabilization was made by Mixter and Osgood in 1910 by fixation of the spinous processes with a heavy silk thread 1,2.
Posterior cervic...

Accessory transverse foramen
An accessory transverse foramen, also known as a double transverse foramen, are a second, smaller foramen in the transverse process of typical cervical vertebrae 1. They are smaller than the transverse foramen, and may be unilateral or bilateral. Small studies have suggested a prevalence of 8-...

Retropharyngeal pseudothickening
Retropharyngeal pseudothickening is a mimic of retropharyngeal soft tissue thickening caused by neck flexion (which may also exacerbate airway obstruction), swallowing, or expiration.
It is important to consider when evaluating lateral cervical radiographs and sagittal cross-sectional imaging ...
