Pediatric cervical spine fracture case report: Best practice to delay transition to rear-facing restraint
Bibliographic record
Abstract
Pediatric physicians and motor vehicle safety experts have been advocating for change in child passenger restraint practices for decades. As professional recommendations evolve to support extended rear-facing restraint, actual practices remain disparate. We report a case of pediatric cervical spine fracture due to motor vehicle collision, an uncommon, yet predictable, pattern of injury for which prevention education is undoubtedly preferable to managing the consequences of premature forward-facing in vulnerable pediatric patients. Currently, 9 kg is a minimum legal standard for forward-facing child restraint system use in Ontario, rather than a recommended transition time. We advise that parents should be counselled on the benefits of rear-facing as long as possible and discuss realistic transition times using their child restraint system manual as a reference, with the goal of approaching, but not exceeding, the maximum weight, height and fit requirements for optimal safety.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
