Whiplash: Neck Pain After a Car Crash Explained

Whiplash — formally known as cervical acceleration-deceleration (CAD) injury — is the most frequently sustained injury in motor vehicle accidents. Despite being so common, it is frequently misunderstood, underestimated, and undertreated. Understanding the mechanics of whiplash helps explain why it can produce such lasting and varied symptoms.

The Mechanism of Whiplash

During a rear-end impact, the sequence of events in the cervical spine occurs faster than the blink of an eye. As the car lurches forward, the lower cervical vertebrae are pushed forward by the seat while the upper vertebrae and head lag behind. This creates a characteristic S-shaped deformation of the cervical spine — compressing lower segments while tensioning upper segments simultaneously. The subsequent forward rebound completes the injury pattern.

What Gets Damaged

The structures most vulnerable in whiplash include:

• Cervical facet joints — compressed and sheared during the injury
• Intervertebral discs — may herniate or sustain endplate injury
• Spinal ligaments — stretched or torn by the extreme range of motion
• Paraspinal muscles — acutely strained and may go into prolonged spasm
• Nerve roots — may be pinched by disc or joint swelling

The Full Spectrum of Whiplash Symptoms

Whiplash symptoms extend well beyond neck pain. Headaches, dizziness, jaw pain (TMJ), cognitive difficulty ("brain fog"), visual disturbances, and upper extremity symptoms can all accompany cervical acceleration-deceleration injury. Prompt chiropractic evaluation addresses the full picture of your injuries.
