1. A 32-year-old patient is involved in a high-speed motor vehicle collision. He
reports severe midline thoracolumbar pain. What is the most appropriate initial
approach?
A. Allow the patient to sit upright for comfort
B. Obtain lumbar radiographs before examining the patient
C. Maintain spinal motion restriction while performing the primary survey
D. Perform active range-of-motion testing of the spine
Answer: C. Maintain spinal motion restriction while performing the primary
survey
Rationale: ATLS management prioritizes airway, breathing, circulation,
disability, and exposure while maintaining appropriate spinal motion restriction
when spinal injury is suspected.
2. Which mechanism is particularly concerning for thoracolumbar spine injury?
A. Low-energy twisting while walking
B. High-energy axial loading or flexion-distraction force
,C. Minor isolated shoulder impact
D. Superficial extremity abrasion
Answer: B. High-energy axial loading or flexion-distraction force
Rationale: Significant axial loading, flexion, extension, rotation, and flexion-
distraction mechanisms can produce unstable thoracolumbar injuries.
3. A patient with blunt trauma has midline thoracolumbar tenderness. What
does this finding indicate?
A. Thoracolumbar fracture is excluded
B. Spinal cord injury is definitely present
C. Only muscular injury is likely
D. Thoracolumbar imaging should be considered based on the clinical context
Answer: D. Thoracolumbar imaging should be considered based on the clinical
context
Rationale: Midline tenderness after trauma raises concern for spinal injury and
should prompt appropriate evaluation, particularly when combined with a
significant mechanism or other risk factors.
4. Which finding is most concerning for neurologic compromise from a
thoracolumbar injury?
A. Localized muscle soreness
B. Mild bruising
C. New bilateral lower-extremity weakness
D. Isolated abdominal tenderness
Answer: C. New bilateral lower-extremity weakness
Rationale: New motor deficits suggest possible spinal cord or nerve-root
compromise and require urgent assessment and appropriate management.
5. Which region is included in the thoracolumbar junction?
A. Cervical vertebrae C1–C4
B. Thoracic vertebrae and the T12–L1 transition region
,C. Sacral vertebrae only
D. Coccygeal vertebrae only
Answer: B. Thoracic vertebrae and the T12–L1 transition region
Rationale: The thoracolumbar junction, particularly T11–L2, is a common
location for traumatic spinal injuries because of its transition from the relatively
rigid thoracic spine to the more mobile lumbar spine.
6. A trauma patient is hypotensive and has a suspected thoracolumbar fracture.
What should be done first?
A. Obtain magnetic resonance imaging
B. Perform a detailed spinal classification
C. Address life-threatening problems identified during the primary survey
D. Immediately perform flexion-extension radiographs
Answer: C. Address life-threatening problems identified during the primary
survey
Rationale: ATLS emphasizes immediate treatment of life threats before definitive
evaluation of non-life-threatening spinal injuries.
7. Which structure provides important posterior stability to the thoracolumbar
spine?
A. Diaphragm
B. Clavicle
C. Posterior ligamentous complex
D. Patellar tendon
Answer: C. Posterior ligamentous complex
Rationale: The posterior ligamentous complex contributes substantially to spinal
stability, and disruption can indicate an unstable injury.
8. Which injury pattern is classically associated with a flexion-distraction
mechanism?
, A. Jefferson fracture
B. Odontoid fracture
C. Chance-type injury
D. Scaphoid fracture
Answer: C. Chance-type injury
Rationale: Flexion-distraction injuries produce horizontal disruption through the
vertebral body, posterior elements, or both and are classically represented by
Chance-type injuries.
9. A patient has a seat-belt sign across the abdomen after a collision. What
additional injury should increase concern for?
A. Isolated wrist fracture
B. Flexion-distraction injury of the thoracolumbar spine
C. Isolated clavicle fracture
D. Ankle sprain
Answer: B. Flexion-distraction injury of the thoracolumbar spine
Rationale: A prominent seat-belt sign is associated with flexion-distraction
spinal injuries and may also indicate significant intra-abdominal injury.
10. Which imaging modality is generally most useful for characterizing suspected
thoracolumbar fractures in a major trauma patient?
A. Plain abdominal ultrasound
B. Computed tomography
C. Electrocardiography
D. Bone scan
Answer: B. Computed tomography
Rationale: Computed tomography provides detailed assessment of vertebral
fractures, alignment, posterior elements, and canal involvement and is
commonly incorporated into modern trauma imaging.
11. What is a major limitation of plain radiographs in thoracolumbar trauma?
