Burst fracture
A severe spinal fracture from high-energy axial loading.
A burst fracture is a type of traumatic spinal injury in which a vertebra breaks from a high-energy axial load, such as traffic collisions, falls from a great height or high speed, and some kinds of seizures. Shards of vertebra penetrate surrounding tissues and sometimes the spinal canal, and the injury is considered more severe than compression fractures because long-term neurological damage can follow.
- cause
- High-energy axial load (e.g., traffic collisions, falls, seizures)
- diagnosis
- Medical imaging (X-rays, MRIs)
- treatment options
- Surgical (spinal fusion, artificial/cadaver bone replacement) or nonsurgical (TLSO brace)
- neurological risk
- Immediate or progressive neurologic deficits
- long-term effects
- Permanent decrease in anterior height, kyphosis, possible neurological deterioration
Lore & Background
Burst fractures result from high-energy axial loads such as traffic collisions, falls from great height or high speed, and some seizures. The vertebra breaks into shards that can penetrate surrounding tissues and the spinal canal, potentially causing immediate or progressive neurological deficits. Diagnosis is made through medical imaging, and severity is categorized by deformity, canal compromise, loss of vertebral body height, and neurologic deficit.
Reader's Guide
Burst fractures are significant because they represent a severe spinal injury with potential for long-term neurological damage, unlike compression fractures. Treatment requires immediate hospitalization, with management determined by imaging and stability assessment. Surgical options include spinal fusion or vertebral replacement, while nonsurgical management uses a full-body TLSO brace for 2–3 months followed by physical therapy. The injury results in permanent structural changes and possible progressive neurological dysfunction over the patient's lifetime.
Did You Know?
- Burst fractures are considered more severe than compression fractures because long-term neurological damage can follow.
- Neurologic deficits can reach their full extent immediately or progress for a prolonged time.
- Nonsurgical management involves wearing a custom-molded TLSO brace 24/7 for 2–3 months.
- Surgical management is required when the burst fracture is unstable.
Frequently Asked Questions
What is a Burst fracture?
A burst fracture is a traumatic spinal injury in which a vertebra shatters under a powerful axial force, sending bone fragments into adjacent soft tissue and potentially the spinal canal. It is classified as more severe than a simple compression fracture because of the heightened risk of lasting nerve damage.
What causes a Burst fracture?
The injury typically results from a high-energy axial load driving force straight down the vertebral column, such as a traffic collision, a fall from significant height, or certain seizure events.
How do doctors diagnose a Burst fracture?
Medical imaging is the standard diagnostic route, with X-rays providing the initial bony picture and MRIs revealing soft-tissue and spinal-canal involvement. Together they confirm the pattern of vertebral collapse and fragment displacement.
How is a Burst fracture treated?
Depending on severity, management ranges from a thoracolumbosacral orthosis (TLSO) brace for stable cases to surgery involving spinal fusion or replacement with artificial or cadaver bone. The choice hinges on fragment position and the patient's neurological status.
What long-term effects can a Burst fracture cause?
Survivors may face a permanent loss of anterior vertebral height, progressive kyphosis, and—most critically—immediate or worsening neurological deficits if displaced fragments impinge on the spinal cord.
