Retrolistheses are most easily diagnosed on lateral x-ray views of the spine. Views where care has been taken to expose for a true lateral view without any rotation offer the best diagnostic quality. Retrolistheses are found most prominently in the cervical spine and lumbar region but can also be seen in the thoracic area.
A 64-slice CT with reconstructions does not entirely rule out ligamentous injury leading to instability, but is a practical means of identifying the majority of C-spine injuries in obtunded patients. MR C-spine has frequent false-positives, limiting its usefulness. [citation needed] In these cases, a consultation with a Spine Surgery specialist ...

In radiology, the thumbprint sign, or thumbprinting, is a radiologic sign found on a radiograph that suggests the diagnosis of either epiglottitis or intestinal ischemia.. In a lateral C-spine radiograph, the sign is caused by a thickened free edge of the epiglottis, which causes it to appear more radiopaque than normal, resembling the distal thumb.
X-rays are used to measure the lumbar curvature. On a lateral X-ray, a normal range of the lordotic curvature of between 20° and 60° has been proposed by Stagnara et al., as measured from the inferior endplate of T12 to the inferior endplate of L5. [18]
The atlas (C1) is the topmost vertebra, and along with the axis forms the joint connecting the skull and spine. It lacks a vertebral body, spinous process, and discs either superior or inferior to it. It is ring-like and consists of an anterior arch, posterior arch, and two lateral masses. The axis (C2) forms the pivot on which the atlas rotates.
The upper cervical spine has a curve, convex forward, that begins at the axis (second cervical vertebra) at the apex of the odontoid process or dens and ends at the middle of the second thoracic vertebra; it is the least marked of all the curves. This inward curve is known as a lordotic curve. A thoracic spine X-ray of a 57-year-old male.
The clivus is an important landmark for checking for anatomical atlanto-occipital alignment. When viewed on a lateral C-spine radiograph, the clivus forms a line which, if extended, is known as Wackenheim's clivus line. Wackenheim's clivus line should pass through the dens of the axis or be tangential to it. [9]
