Evolution of Thoracolumbar Trauma Classification Systems: Assessing the Conflict Between Mechanism and Morphology of Injury
Bibliographic record
Abstract
Spine specialists continue to debate how to best treat various types of thoracolumbar injuries. The first step in standardizing optimal treatment is for orthopedists, neurosurgeons, and rehabilitation specialists to arrive at a consensus regarding the classification of thoracolumbar fractures. Beginning with Böhler in 1931, there have been several attempts to forward thoracolumbar injury classifications systems since the advent of the radiograph. Throughout this period, surgeons and other health care providers have debated whether an effective injury classification system should be based upon the mechanism of injury or the morphology of injured tissues. A systematic review of the literature on thoracolumbar spine trauma classification systems, emphasizing contrasting features of mechanistic and morphometic paradigms, was conducted by 40 spine surgeons from 15 trauma centers in 10 countries. As a contemporary example of this debate, we also discuss 2 recently validated thoracolumbar-fracture classification systems developed by the Spine Trauma Study Group: one is predicated on injury mechanism (Thoracolumbar Injury Severity Score [TLISS]) and the other uses injury morphology (Thoracolumbar Injury Classification and Severity Score [TLICS]).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
