Evaluation and treatment of patients
with Thoracolumbar Spine Trauma

Thoracolumbar spine trauma is a significant cause of disability, affecting individuals across various age groups, and often resulting from blunt trauma. Injuries in this region of the spine can be debilitating, leading to pain, neurological deficits, and long-term complications. The thoracolumbar spine consists of three parts: the rigid thoracic spine, the transitional thoracolumbar junction, and the more flexible lumbar spine. Given the complexity of these injuries, the management of thoracolumbar spine trauma remains a topic of ongoing debate, particularly regarding classification, surgical vs. non-surgical treatment, and the timing of intervention. Advances in treatment protocols aim to optimize patient outcomes and reduce the burden of disability.

How Common It Is and Who Gets It? (Epidemiology)

Thoracolumbar spine trauma is commonly seen in patients who experience blunt trauma, such as car accidents, falls, or sports injuries. It is prevalent among older adults due to osteoporosis and other degenerative conditions. The incidence of traumatic spinal fractures is significant, with estimates suggesting that 50% to 90% of the 160,000 traumatic spinal fractures occurring annually in North America are located in the thoracolumbar spine.

Why It Happens – Causes (Etiology and Pathophysiology)

Trauma to the thoracolumbar spine can be caused by various factors, including high-energy blunt force injuries, osteoporosis, or degenerative diseases. The structural composition of the thoracolumbar region—where the thoracic spine meets the more flexible lumbar spine—makes it especially vulnerable to fractures and dislocations. Conditions like osteoporosis increase the risk of vertebral compression fractures, which can lead to instability and nerve compression.

How the Body Part Normally Works? (Relevant Anatomy)

The thoracolumbar spine is composed of vertebrae from T10 to L5, with the T10-L2 area acting as the transitional region between the more rigid thoracic spine and the flexible lumbar spine. This region supports much of the body’s weight and facilitates movement while protecting the spinal cord. Nerves exit the spinal cord at each vertebral level, and damage to these nerves can lead to significant symptoms, including pain, numbness, or weakness.

What You Might Feel – Symptoms (Clinical Presentation)

Symptoms of thoracolumbar trauma can range from localized back pain and tenderness to severe neurological impairment. Common signs include:

• Acute back pain, often exacerbated by movement or pressure.

• Neurological deficits such as weakness, numbness, or tingling in the legs.

• Bowel or bladder dysfunction, in severe cases, indicating nerve involvement.

• Difficulty standing or walking due to instability.

How Doctors Find the Problem? (Diagnosis and Imaging)

Diagnosis begins with a detailed history and physical examination. Imaging studies, particularly X-rays, CT scans, and MRIs, are crucial for assessing the extent of spinal fractures, ligament injuries, and any compression of the spinal cord or nerve roots. MRI is particularly useful for evaluating soft tissue damage and nerve involvement.

Classification

Thoracolumbar fractures are typically classified based on injury morphology, using systems like the AO Spine Classification or the Thoracolumbar Injury Classification and Severity Scale (TLICS). These systems consider the degree of spinal injury, fracture type, neurological deficits, and the stability of the spine. This classification helps guide treatment decisions.

Radiological Evaluation

Providers may consider using magnetic resonance imaging to evaluate the integrity of the posterior ligamentous complex when making decisions about surgery since it has been demonstrated that magnetic resonance imaging can impact the management of as many as 25% of patients with thoracolumbar fractures.

Neurological Assessment

Several neurological assessment scales, such as the Sunnybrook Cord Injury Scale, Frankel Scale for Spinal Cord Injury, and Functional Independence Measure, have exhibited internal reliability and validity in treating patients with thoracic and lumbar fractures.

The initial American Spinal Injury Association Impairment Scale grade, sacral sensation, ankle spasticity, urethral and rectal sphincter function, and AbH motor function are potential predictors of neurological function and outcomes in patients with thoracic and lumbar fractures.

Other Problems That Can Feel Similar (Differential Diagnosis)

Other conditions that may mimic thoracolumbar spine trauma include:

• Muscle strains or ligament sprains in the lower back.

• Sacroiliac joint dysfunction.

• Herniated discs or degenerative spine conditions.

• Abdominal conditions such as kidney stones or pancreatitis.

Treatment Options

Non-Surgical Care: Includes rest, pain management (NSAIDs, analgesics), bracing, and physical therapy.

Surgical Care: Indicated for unstable fractures, significant neurological impairment, or failure of conservative treatments. Surgical options include decompression (discectomy, laminectomy), spinal stabilization (fusion), or a combination of both.

Novel Surgical Strategies

It is recommended that surgeons should be mindful that adding arthrodesis to instrumented stabilization in the surgical management of thoracolumbar burst fractures has not been demonstrated to affect clinical or radiological outcomes.

Furthermore, this approach may lead to greater blood loss and a longer duration of surgery. Equivalent clinical outcomes have been suggested by the evidence, and thus the use of both open and percutaneous pedicle screws for stabilization may be considered in the treatment of thoracolumbar burst fractures.

Recovery and What to Expect After Treatment

Non-Surgical Recovery: For patients treated conservatively, recovery includes pain management, physical therapy, and gradual return to activity. Most patients with stable fractures experience improvement in 6 to 12 weeks.

Surgical Recovery: Surgical patients may require 1-5 days of hospitalization, followed by rehabilitation. Full recovery from surgery may take several months, depending on the procedure and the patient’s overall health.

Possible Risks or Side Effects (Complications)

Surgical risks include:

• Infection.

• Bleeding.

• Nerve damage.

• Complications from anesthesia.

• Failure of fusion or hardware issues (screws/rods).

Non-surgical risks include prolonged pain, lack of improvement with conservative treatment, or progression of deformity.

Long-Term Outlook (Prognosis)

Patients who undergo successful surgical intervention typically have a good prognosis, with pain relief and improved function. However, complications such as adjacent segment degeneration or non-union can arise. The long-term outlook varies based on the extent of the trauma, the treatment used, and the presence of any underlying conditions like osteoporosis.

Out-of-Pocket Costs

Medicare

CPT Code 63030 – Lumbar Discectomy (Decompression): $225.06
CPT Code 63047 – Lumbar Laminectomy (Decompression): $271.76
CPT Code 22612 – Spinal Fusion (Posterior/Posterolateral): $382.85
CPT Code 22558 – Anterior Lumbar Interbody Fusion (ALIF): $368.50
CPT Code 22630 – Posterior Lumbar Interbody Fusion (PLIF/TLIF): $387.42

Under Medicare, 80% of the approved cost for these spinal procedures is covered once the annual deductible has been met. The remaining 20% is typically the patient’s responsibility. Supplemental insurance plans—such as Medigap, AARP, or Blue Cross Blue Shield—typically cover this 20%, meaning most patients will have little to no out-of-pocket expenses for Medicare-approved spinal surgeries. These supplemental plans work directly with Medicare to provide full coverage for decompression, fusion, instrumentation, and interbody stabilization procedures.

If you have secondary insurance—such as Employer-Based coverage, TRICARE, or Veterans Health Administration (VHA)—it acts as a secondary payer once Medicare processes the claim. After your deductible is satisfied, the secondary plan may cover any remaining balance, including coinsurance or any uncovered charges. Most secondary plans have a small deductible, typically between $100 and $300, depending on the specific policy and whether the surgery is performed at an in-network facility.

Workers’ Compensation
If your lumbar spine condition requiring these procedures is work-related, Workers’ Compensation will cover all treatment-related costs, including surgery, hospitalization, and rehabilitation. You will have no out-of-pocket expenses under an accepted Workers’ Compensation claim.

No-Fault Insurance
If your lumbar spine injury or condition was caused or worsened by a motor vehicle accident, No-Fault Insurance will cover the entire cost of your surgery, including decompression, fusion, instrumentation, and interbody device placement. The only possible out-of-pocket expense may be a small deductible depending on your individual policy terms.

Example
John, a 67-year-old patient with lumbar disc degeneration and nerve compression, underwent lumbar discectomy (CPT 63030) and posterior lumbar interbody fusion (CPT 22630) with instrumentation (CPT 22842) for pain relief and spinal stabilization. His estimated Medicare out-of-pocket costs were $225.06 for the discectomy, $387.42 for the fusion surgery, and $185.26 for the instrumentation. Since John had supplemental insurance through Blue Cross Blue Shield, the 20% that Medicare did not cover was fully paid, leaving him with no out-of-pocket expenses for his surgery.
