![]() ![]() If there is any asymmetry between the articular spaces (mainly lines 3) this would be most concerning for either a Jefferson (or Burst) fracture of C1 or a dens fracture (or Odontoid fracture) of C2 or possible transverse ligament injury. Masses this would be most concerning for a Jefferson (or Burst) fracture of C1. Figure 3: Example of a slightly rotated not ideal lateral projection of the cervical spine in (A) and an x-ray of an ideal lateral projection in (B). Facet joints are best visualized when we have a proper lateral projection. If the lateral masses of C1 extend out beyond the C2 lateral Next, check if the x-ray is a real lateral view, or if it is slightly rotated. Spaces between the dens and the lateral masses of C1 Spaces between the lateral masses of C1 and the body of C2 (axis).

Make sure there is no asymmetry of the articular Furthermore, an MRI is preferred over a CT scan, since the CT scan may not be able to show the maximal positions of displacement in the fractures. While this radiographic rule can be used, it is important to recognize that it may not always correlate well and management decisions should not be made without first obtaining an MRI. laterally to include the entire cervical spine and its spinous processes anteriorly to include the soft tissue of the neck superiorly to include all of C1/base of skull inferiorly to include to at least T1 (EAM to sternal notch) orientation. The rule of Spence would suggest that if there is more than a combined (total of both sides) overhang of 6.9 mm or more of the lateral masses of C1 in relation to the C2 lateral masses then there is concern for an injury to the transverse ligament and an MRI should be done. 15° cranial tilt of the central ray collimation.Film selection: 8 × 10: Film placement: Place vertically in Bucky. Shielding: Secure lead apron around patient. Move the slider bar toward the patient until it touches the anterior aspect of the cervical spine at C4. Make sure the lateral masses of C1 (atlas) do not hang over the lateral masses of C2 (axis). Place the base bar of the calipers against the posterior aspect of the cervical spine at the level of C4.Note: Scroll over or tap over image to see lines & labels.
