L3-L5 Vertebral Fractures: Does It Always Mean Spinal Cord Injury?

No. A fracture of the L3–L5 vertebrae does not automatically imply spinal cord injury.

Why

• The spinal cord typically ends at L1–L2 (conus medullaris).
• Below this, the cauda equina (nerve roots) occupies the canal—more resilient, peripheral nerves.
• Fractures can be stable (no neurologic deficit) or unstable.

Required Evaluation

1. Imaging: CT (bony detail), MRI (soft tissue, cord/root compression).
2. Neurological exam: Motor, sensory, reflexes, rectal tone, bulbocavernosus reflex.
3. ASIA classification if deficit present.

Management ranges from bracing to surgical stabilization depending on stability and neurologic status.
