Whiplash: A Common Neck Injury

Peer Reviewed

Whiplash is a collective term used to describe the injuries to the cervical spine (neck). This condition often results from an automobile collision, which suddenly forces the head and neck to whip back and forth (hyperflexion/hyperextension).

The neck consists of 7 cervical vertebrae (C1-C7) held together by muscles and ligaments, intervertebral discs (shock absorbers), joints enabling motion, and a system of nerves. The complexity of the neck's anatomy coupled with its diverse range of motion makes it susceptible to whiplash.

Whiplash Symptoms
The symptoms of whiplash may include neck pain, tenderness and stiffness, headache, dizziness, nausea, shoulder and/or arm pain, paresthesias (numbness/tingling), blurred vision, and in rare cases difficulty swallowing. Symptoms may appear as quickly as two hours following injury.

The symptoms usually result from injury to the neck's soft tissues; the intervertebral discs, muscles, and ligaments. Muscle tears characteristically present with burning pain accompanied by tingling sensations. Ligaments affected by excessive joint movement can cause muscles to defensively tighten limiting motion. 'Wry neck', a condition associated with whiplash, occurs when the neck muscles responsible for head rotation/extension cause the neck to twist involuntarily.

Age and pre-existing health conditions (e.g., arthritis) may increase the severity of whiplash. As people age range of motion declines, muscles lose flexibility and strength, and intervertebral discs and ligaments lose some of their elasticity.

A physical and neurological examination is performed to evaluate the patient's general condition.

Initially, the physician orders radiographs (x-rays) to determine if fracture exists. Depending on the patient's symptoms, a CT scan, MRI, and/or other imaging tests may be necessary to assess the condition of the cervical spine's soft tissues (intervertebral discs, muscles, ligaments).

Whiplash: Treatment and Recovery
Michael G. Fehlings, MD, PhD, FRCSC, FACS
Dr. Albert has presented very good and comprehensive information about Whiplash. Whiplash injury is most commonly described as occurring following a rear-end collision with an extension-flexion injury of the cervical spine. In the majority of cases, the pain following a whiplash injury is self-limiting and will resolve over several weeks to months as the soft tissues of the neck heal. Surgery is rarely required and is limited to cases associated with an unstable cervical fracture or a cervical disc herniation with persisting nerve root or spinal cord compression.
