Reliability of a novel classification system for thoracolumbar injuries: the Thoracolumbar Injury Severity Score.

Study Design: Prospective study of 5 spine surgeons rating 71 clinical cases of thoracolumbar spinal injuries using the Thoracolumbar Injury Severity Score (TLISS) and then re-rating the cases in a different order 1 month later.

Objective: To determine the reliability of the TLISS system.

Summary Of Background Data: The TLISS is a recently introduced classification system for thoracolumbar spinal column injures designed to simplify injury classification and facilitate treatment decision making.
