What trauma would be induced from #7?

• A. Inferior vertical strain
• B. Left lateral strain
• C. Right lateral strain
• D. Left sidebending rotation

Answer: (C)

Trauma can create a side-to-side shear on the sphenobasilar synchondrosis, producing a lateral strain pattern. When the pattern shown in the figure indicates the cranial bones have shifted off the midline toward the right, that corresponds to a right lateral strain. In this pattern, the parts of the skull move primarily to the right relative to the midline, rather than vertically (which would be an inferior vertical strain) or to the left (left lateral strain), or producing a sidebending-rotation pattern that would show a different combination of landmarks. So the observed trauma aligns with a right lateral strain.
