Most thoracolumbar fractures are located between which vertebral levels?

Explanation:
The main idea is that most thoracolumbar fractures occur at the thoracolumbar junction, where the rigid thoracic spine meets the more mobile lumbar spine. This transition concentrates stress during trauma, especially with bending and shear forces, making injuries most common here. The range spanning T12 to L4 covers this transitional zone, which is why it’s the best fit. Regions higher in the thoracic spine (like T1–T4) are more protected by the rib cage, and regions lower in the lumbar spine (like L2–L5) lie away from the abrupt junction, so they’re less typical sites for these fractures.
