What trauma would be induced from #3?

• A. Left Lateral Strain
• B. Right Torsion
• C. Left Torsion
• D. Superior Vertical Strain

Answer: (B)

Recognizing a torsional cranial pattern is about how the sphenoid and occiput move relative to each other around the sphenobasilar synchondrosis. In a torsion, these two bones rotate in opposite directions. When it’s a right torsion, the sphenoid rotates to the right while the occiput rotates to the left. So the trauma would be a twisting force that produces a rightward rotation of the sphenoid relative to the occiput. That’s why this option is the best description for a right torsion pattern. The other patterns involve either a side-to-side shift (lateral strain) or a vertical displacement (vertical strain) and don’t match the opposite-direction rotation seen in torsion.
