Back Pain After a Car Accident
Provo, Utah — Mid-Back & Low Back. Disc Injury. Fellowship-Level Biomechanical Evaluation.
Low back and mid-back pain following a car accident can range from acute muscle strain to disc herniation to fracture. The evaluation determines the injury type and drives the treatment plan. Most spines do not get the evaluation they need after a collision.
How Car Accidents Injure the Back
In a rear-end or frontal collision, the lumbar and thoracic spine absorbs significant compressive and shear forces. The seatbelt — while life-saving — constrains the pelvis while the upper body continues to move, creating a rotational stress at the lumbar spine and thoracolumbar junction that can damage facet joints, intervertebral discs, and spinal ligaments.
Low back pain after a car accident may be caused by disc herniation, facet joint injury, sacroiliac joint disruption, or muscular strain — often a combination. Thoracic (mid-back) pain is less common but frequently involves rib-vertebra junction irritation and thoracic facet syndrome from the rotational forces of a collision.
Why Most Post-Accident Back Pain Evaluations Are Incomplete
Emergency room evaluation rules out fracture and major neurological compromise — this is essential. But the mechanical analysis of how the collision has affected spinal segment motion, disc integrity, and ligament stability requires a specialized evaluation that ERs and most clinics do not perform. A full-spine standing X-ray with angular measurements, combined with motion X-ray at any segments showing suspected instability, gives a complete picture of the biomechanical damage that a static MRI taken in a resting position cannot provide.
Symptoms and Signs
Lumbar (Low Back)
- Low back pain worsened by sitting
- Pain radiating into the hip or leg
- Stiffness getting out of bed
- SI joint or buttock pain
Thoracic (Mid Back)
- Pain between the shoulder blades
- Sharp pain with deep breathing
- Pain wrapping around the ribs
- Worsened by rotation
Disc/Nerve Signs
- Sciatica (radiating leg pain)
- Numbness or tingling in legs
- Weakness in lower extremity
- Pain worse with coughing/sneezing
Fellowship-Level Trauma Evaluation
Our doctors hold a Fellowship in Spinal Biomechanics and Trauma (FSBT) — one of the highest post-doctoral credentials available in chiropractic, including advanced training in trauma evaluation, MRI interpretation, and motion X-ray analysis. We have been serving Utah County since 1999 and work directly with personal injury attorneys, local MRI facilities, and spine specialists.
If you were in a car accident, your injury documentation begins on day one. The longer you wait, the harder it is to establish a clear relationship between the collision and your injuries. We can evaluate you, document the clinical findings thoroughly, and coordinate with your attorney and insurance carrier.

Research on Lumbar Injury in Motor Vehicle Collisions
Back pain after a car accident is frequently undertreated because standard emergency evaluations focus on ruling out fracture — not on identifying the disc, facet, or ligament injuries that produce persistent mechanical pain.
Svensson et al. — Lumbar Loading in Rear-End Impact
Biomechanical analysis demonstrated that rear-end collisions produce S-curve deformation of the lumbar spine — a loading pattern that concentrates stress on posterior disc annulus and facet joints in a way that is not reproduced in standard traction or forward bending.
Deyo & Weinstein (2001) — Low Back Pain Diagnosis
Published in the New England Journal of Medicine, this landmark review established that most low back pain has a specific mechanical driver that can be identified with careful clinical examination — and that imaging alone is insufficient to direct treatment.
Schwarzer et al. — Sacroiliac Joint Pain Prevalence
Controlled studies using diagnostic injections found the sacroiliac joint to be the primary pain source in approximately 13-30% of patients with low back pain — a structure particularly vulnerable to loading during seatbelt restraint in collision events.
