Rotational injuries typically result in what type of injury?

• A. Localized skull fracture
• B. Hematoma only
• C. No injury
• D. A diffuse injury such as a concussion and widespread bleeding

Answer: (D)

Rotational forces cause the brain to spin inside the skull, creating widespread shearing of axons and tiny vessels. That global disruption leads to a diffuse brain injury rather than a single focal lesion. Therefore, a diffuse injury such as concussion with widespread bleeding best fits rotational injuries. A localized skull fracture results from a direct impact and is a focal injury, not typical of rotational forces. A hematoma alone suggests a limited bleed, which doesn’t capture the broad injury pattern, and saying there’s no injury ignores the common diffuse damage produced by rotational motion.
