Herniated nucleus pulposus is described as rare in whiplash injuries. Which statement is true?

• A. Not specified
• B. Both
• C. False
• D. True

Answer: (D)

In whiplash injuries, the typical findings are soft-tissue strain and facet joint irritation rather than a ruptured disc. A herniation of the nucleus pulposus requires a rupture of the annulus fibrosus and extrusion of disc material, which is less likely to occur with the mechanics of a common whiplash injury. Because most acute whiplash cases involve ligaments, muscles, and joints rather than a frontal rupture of the disc, herniated nucleus pulposus is described as rare. When there are persistent radicular symptoms, imaging like MRI is considered to evaluate for disc pathology, but overall the incidence after whiplash remains relatively low. That’s why the statement is true.
