Retropulsion of the T6 vertebra refers to the backward displacement of part or all of the sixth thoracic vertebral body into the spinal canal. This typically occurs when the vertebra is fractured or weakened—such as in a burst fracture—so that bone fragments are pushed posteriorly under force. Because the thoracic spine forms part of the rigid rib cage, retropulsion at T6 can impinge the spinal cord or nerve roots, leading to neurological symptoms below the level of injury. In simple terms, imagine the middle of your back getting hit so hard that a piece of bone from the sixth rib-bearing bone in your spine is shoved backward toward the spinal cord.
Retropulsion of the T6 vertebra refers to a condition in which a fragment or the entire vertebral body of the sixth thoracic (T6) vertebra is displaced backward into the spinal canal. This displacement can compress the spinal cord or nerve roots, leading to pain, neurological deficits, and compromised spinal stability. Retropulsion typically results from high-energy trauma—such as falls from height, motor vehicle collisions, or severe sports injuries—but can also occur in the setting of osteoporotic fractures or metastatic lesions that weaken the vertebral body. In the thoracic spine, the relatively rigid rib cage tends to confine motion, so retropulsion at T6 often signifies a severe injury that may require urgent intervention to prevent permanent spinal cord damage.
Types of T6 Retropulsion
1. Traumatic Burst Retropulsion (AO Type A3.)
In a high-energy injury—like a fall from height or a car crash—the T6 vertebral body can shatter outward in all directions. When the central fragment moves backward into the spinal canal, it’s called a burst fracture with retropulsion. This form is subclassified into incomplete burst (A3.1), burst-split (A3.2), and complete burst (A3.3) in the AO Spine system, based on how much the vertebra fragments and retropulses.
2. Degenerative Retrolisthesis
Over years of wear and tear on intervertebral discs and facet joints, one vertebra can gradually slip backward relative to its neighbor—a process called retrolisthesis. At T6, this degeneration-driven retropulsion is uncommon but can occur with severe disc collapse or facet arthritis, leading to a chronic, low-grade backward shift.
3. Pathological Retropulsion from Tumor
Primary bone tumors (like osteoblastoma) or metastatic cancers (breast, lung, prostate) can weaken the T6 vertebral body. As the bone erodes, small fragments may collapse and press backward into the canal, causing retropulsion without a major trauma.
4. Infectious Collapse (Spondylodiscitis)
Infections such as tuberculosis or pyogenic spondylodiscitis can destroy vertebral bone. As the infected T6 body collapses, segments may retropulse into the spinal canal. This process is usually more gradual than in trauma but can produce severe canal narrowing.
5. Iatrogenic Retropulsion
Surgical procedures, like aggressive laminectomy or overzealous vertebral body resection, can destabilize T6. Post-operative collapse or instrumentation failure may allow fragments or the vertebral body itself to shift backward into the canal.
Causes of Retropulsion at T6
-
High-Impact Trauma
Falling from a height or a car collision can fracture the T6 vertebra so severely that bone fragments are driven into the spinal canal. -
Osteoporosis
Weakened, porous bones can collapse under normal loads, allowing retropulsion of compressed fragments. -
Spinal Tumors
Cancer growth within the T6 body erodes bone, causing collapse and posterior fragment displacement. -
Infection-Related Bone Loss
Tuberculosis or bacterial infections destroy vertebral bone, leading to slow collapse and retropulsion. -
Long-Term Corticosteroid Use
Chronic steroids reduce bone density, increasing risk of compression and fragment retropulsion even after minor trauma. -
Metastatic Disease
Secondary cancer deposits in vertebrae weaken structural integrity, predisposing to retropulsion. -
Primary Bone Tumors
Osteolytic tumors, like multiple myeloma, dissolve bone from the inside out, enabling fragment collapse. -
Degenerative Disc Disease
Severe disc space narrowing alters load-sharing, causing uneven pressure on T6 and fragment displacement. -
Facet Joint Arthritis
Advanced arthritis changes spine mechanics, leading to micro-fractures and eventual retropulsion. -
Paget’s Disease of Bone

Plasmacytomas in the vertebra dissolve bone, leading to spontaneous collapse and retropulsion. -
Severe Scoliosis Corrective Surgery
Overcorrection or instrumentation failure can destabilize T6 and result in backward fragment movement. -
Iatrogenic Bone Resection
Excessive surgical removal of vertebral tissue can destabilize and allow retropulsion. -
Vertebral Hemangioma Expansion
Aggressive hemangiomas may erode bone and permit fragment collapse. -
Osteomyelitis
Chronic bone infection eats away at T6, enabling retropulsion as the vertebra weakens. -
Traumatic Burst in Osteopenia
Mild trauma in osteopenic spine can cause burst-type retropulsion more easily than in healthy bone. -
Spondyloarthritis Erosion
Inflammatory arthritis affecting spine facets can lead to bone loss and retropulsion. -

Frequently Asked Questions
-
What exactly causes retropulsion of the T6 vertebra?
High-energy trauma such as falls or car accidents can fracture the vertebral body, pushing bone fragments into the spinal canal. Osteoporosis and tumors also weaken the bone, increasing retropulsion risk. -
How is retropulsion diagnosed?
Plain X-rays identify alignment changes; CT scans reveal the degree of bony displacement; MRI detects spinal cord compression and soft-tissue injury. -
Can retropulsion heal without surgery?
Mild cases with minimal displacement and no neurological deficits may heal in a brace over 8–12 weeks under close monitoring. -
What are the risks of delaying surgery?
Prolonged neural compression may cause permanent weakness, sensory loss, or paralysis; vertebral collapse can worsen spinal deformity. -
How long does recovery take?
Bone healing typically occurs in 3–4 months; full functional recovery with rehabilitation may take 6–12 months. -
Will I need a brace?
Many patients wear a rigid thoracic brace for 8–12 weeks to maintain alignment during bone healing. -
Are there long-term complications?
Potential issues include chronic back pain, kyphotic deformity, reduced pulmonary function, or late-onset spinal stenosis. -
When can I return to work?
Desk-based jobs may resume in 4–6 weeks; heavy labor often requires 3–4 months, depending on healing and strength. -
Is physical therapy painful?
Modern protocols emphasize gentle mobilization; therapists adjust intensity to patient tolerance to minimize discomfort. -
What role do supplements play?
Nutrients like vitamin D, calcium, and collagen support bone matrix formation and may speed healing. -
Can exercise worsen the condition?
Unsupervised or high-impact activities can displace healing fragments; always follow a tailored rehabilitation plan. -
What should I know about pain medication?
NSAIDs control inflammation but may interfere with bone healing if used long-term; opioids are reserved for short-term severe pain. -
When is spinal fusion necessary?
Fusion is indicated for unstable fractures or persistent deformity after conservative management. -
Are stem cell treatments proven?
Early studies show promise for enhancing bone repair, but they remain experimental and may not be widely available. -
How can I prevent future vertebral injuries?
