Whiplash: Which Ligaments Can Be Injured, and What the Evidence Shows for Each

By Dr. Justin M. Dick, DC, CNMT, ARRT(N)(CT) | Clear Life Scoliosis and Chiropractic Center, Charlotte, NC | Published October 16, 2026

Whiplash can injure the facet joint capsules, the disc annulus, and the other ligaments that hold one cervical vertebra to the next. The evidence is strongest for the facet capsules. The evidence that whiplash injures the alar and transverse ligaments at the top of the neck, at least as seen on MRI, is weak, and the best studies on that question point the other way. I explain this to patients in Charlotte because the upper neck MRI is sometimes offered as proof of injury, and the research does not support that use.

The Lower Cervical Ligaments

Between each pair of cervical vertebrae below C2 sit the disc annulus, the anterior and posterior longitudinal ligaments, the ligamentum flavum, the interspinous and supraspinous ligaments, and the facet joint capsules. Panjabi grouped the spinal ligaments, disc annulus, and facet capsules as the structures that sustain subfailure injury, meaning a stretch past the elastic limit without a complete tear (Panjabi, Eur Spine J 2006).

The Facet Capsules: The Strongest Evidence

Two lines of evidence converge on the facet capsules. In cadaver spines subjected to a simulated rear impact at 8 g, the capsular ligaments from C2-C3 through C7-T1 elongated significantly more under load than controls (Ivancic, Clin Biomech 2008). In living patients with chronic neck pain after whiplash, placebo-controlled anesthetic blocks confirmed the facet joints as the pain source in 60% (Lord, Spine 1996). One study shows the tissue can be injured; the other shows the joint is a frequent source of chronic pain. Neither, alone, proves both in the same patient.

The Upper Neck: Alar and Transverse Ligaments

The alar and transverse ligaments stabilize the skull on the top two vertebrae. A neurosurgical anatomy review notes that injury to the craniocervical ligaments usually results in death or serious morbidity (Tubbs, J Neurosurg Spine 2011). That describes major trauma. The question for typical whiplash is whether lower-energy injury to these ligaments shows on MRI.

A Norwegian group answered it in three studies. In 1,266 patients with whiplash grades 1 and 2, high-resolution MRI showed moderate to marked high-signal changes in the alar ligaments in 35.5% and in the transverse ligament in 24.6%. The changes were not related to age, type of trauma, or time since trauma, and were more common in men (Vetti, Neuroradiology 2009).

The group then compared 114 patients imaged soon after an acute whiplash injury with 157 uninjured controls. The rate of high-signal changes did not differ between patients and controls (Vetti, Spine 2011). In the same patients followed for 12 months, those changes did not predict disability or neck pain. Posttraumatic stress response and low expectations of recovery did (Vetti, BMC Musculoskelet Disord 2010). The authors concluded that high-resolution upper neck MRI has limited value in these patients.

What I Take From This

For typical whiplash, I do not treat high signal in the alar ligaments on MRI as evidence of injury, because uninjured people show it at the same rate. I focus on the lower cervical segments, where the laboratory and clinical evidence is stronger, and on measurable findings: excessive motion on flexion and extension X-rays and an exam that localizes pain to a segment. A claim built on a finding that controls share at the same rate will not survive a competent opposing expert, and it should not.

For an example of how post-collision imaging findings and outcomes are documented in the peer-reviewed literature, read Dr. Justin Dick's published case report on refractory lumbar pain following a motor vehicle accident in a geriatric patient.

Frequently Asked Questions

Which ligaments can whiplash injure?

Whiplash can injure the facet joint capsules, the disc annulus, and the ligaments between cervical vertebrae. The strongest evidence is for the facet capsules, which showed increased laxity after simulated whiplash in cadaver studies (Ivancic, Clin Biomech 2008).

Does MRI show alar ligament injury after whiplash?

Not reliably. In a controlled study, high-signal changes in the alar and transverse ligaments were as common in uninjured controls as in acute whiplash patients (Vetti, Spine 2011), and they did not predict 12-month outcome (Vetti, BMC Musculoskelet Disord 2010).

Are facet joints a source of pain after whiplash?

Yes. Placebo-controlled anesthetic blocks confirmed facet joint pain in 60% of patients with chronic neck pain after whiplash (Lord, Spine 1996).

What predicts long-term disability after whiplash?

In one 12-month study, posttraumatic stress response and low expectations of recovery predicted disability, while upper neck ligament MRI findings did not (Vetti, BMC Musculoskelet Disord 2010).

How does Dr. Justin Dick evaluate whiplash ligament injuries?

Dr. Justin Dick in Charlotte, NC focuses on the lower cervical segments, using flexion and extension X-rays to measure excessive motion and an exam that localizes pain to a specific level, after fracture has been ruled out.
