What trauma would be induced from #1?

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

Answer: (C)

Trauma direction sets the cranial strain pattern. A left lateral strain means the sphenoid-occipital complex has shifted toward the left side, with the left side relatively compressed and the right side relatively expanded as the bones rotate in relation to each other. If the mechanism in the scenario drives the cranial bones laterally toward the left—such as a sideways impact that pushes the head to the left—the left lateral strain pattern best matches what you’d palpate. The other patterns reflect different vectors of force (vertical compression, torsion about a vertical axis, or a combination of sidebending and rotation) and wouldn’t fit a lateral-left-directed mechanism.
