Burst vs Compression Fracture Charlotte NC | Imaging-Credentialed DC | Clear Life Scoliosis

A compression fracture breaks the front of a vertebral body. A burst fracture breaks the front and the back wall of the vertebral body, the wall that faces the spinal canal. That back wall is what makes the difference, because fragments from it can be pushed toward the spinal cord and nerves. Both happen in car accidents, and patients in Charlotte are often told they have "a fracture" without being told which kind.

The Three-Column Definitions

Denis divided the thoracolumbar spine into three columns in a 1983 study of 412 injuries and grouped major injuries into compression fractures, burst fractures, seat-belt-type injuries, and fracture-dislocations (Denis, Spine 1983). The middle column is the back wall of the vertebral body, the posterior longitudinal ligament, and the back of the disc. Denis found that how the middle column failed correlated with the fracture type and with neurologic injury.

Under that system, a compression fracture is a failure of the anterior column with the middle column intact. A burst fracture is a compression failure of both the anterior and middle columns (StatPearls, Denis Classification). The intact middle column is what keeps a compression fracture from pushing bone into the canal.

How Common Each Is

In a trauma center series of 562 patients with spine fractures, compression-type fractures were the largest group, 54.8% of patients, and 75.3% of all patients had no neurologic deficit (Leucht, Injury 2009). That series used the AO classification, which groups burst fractures with compression-type injuries, so it does not separate the two cleanly.

How They Are Found

The back wall of a vertebral body is hard to judge on a plain X-ray. CT shows it directly. When a fracture is found after a crash, the questions that follow are whether the back wall is involved and whether the posterior ligaments are intact. The TLICS system scores fracture shape, posterior ligament integrity, and neurologic status together to guide treatment (Vaccaro, Spine 2005).

What the Long-Term Evidence Shows

A burst fracture sounds like a surgical injury, and some are. For stable burst fractures in patients with no neurologic deficit, the long-term trial evidence is more interesting. Forty-seven patients with stable thoracolumbar burst fractures and no neurologic deficit were randomized to surgery or to a cast or brace (Wood, J Bone Joint Surg Am 2015). At an average of 18 years, the nonoperative group reported less pain, lower disability scores, and better scores on seven of eight quality-of-life measures. Kyphosis did not differ significantly between groups. Follow-up was incomplete, with 37 of 47 patients located.

A systematic review of 45 studies reached a consistent conclusion: in neurologically intact patients, high-level evidence showed similar functional outcomes with nonoperative and open surgical treatment, and no single nonoperative method was superior (Bakhsheshian, Neurosurg Focus 2014). Most studies excluded patients with neurologic deficits, so those findings do not extend to them.

What This Means After a Crash

Whether a fracture is a compression or a burst fracture, and whether it is stable, is a decision for a spine surgeon with CT and often MRI in hand. My role is earlier: recognizing the findings that need imaging, making sure the patient gets CT, and not treating manually until a fracture has been characterized. After that, I coordinate with the surgeon on what activity and rehabilitation are safe.

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

What is the difference between a burst fracture and a compression fracture?

A compression fracture is a failure of the front of the vertebral body with the back wall intact. A burst fracture also breaks the back wall, the middle column, and can push fragments toward the spinal canal (StatPearls, Denis Classification).

Is a burst fracture worse than a compression fracture?

It involves more of the spine and can affect the spinal canal. Many stable burst fractures without neurologic deficit are still treated without surgery.

Do burst fractures always need surgery?

No. In a randomized trial of stable burst fractures without neurologic deficit, nonoperative patients reported less pain and better function at 16 to 22 years than surgical patients (Wood, J Bone Joint Surg Am 2015).

Can an X-ray tell a burst fracture from a compression fracture?

Not reliably. The back wall of the vertebral body is best judged on CT.

Can a chiropractor treat a spinal fracture?

Not until the fracture is characterized and a surgeon has advised on safe activity. Dr. Justin Dick in Charlotte, NC refers suspected fractures for CT and coordinates care with the treating surgeon.

Where can I get a spinal fracture evaluated after a car accident in Charlotte, NC?
