Spinal Injuries in Canadian Ice Hockey: Documentation of Injuries Sustained from 1943-1999
Bibliographic record
Abstract
OBJECTIVES: Study objectives were: (a) to examine the causes and incidence of major spinal cord injuries sustained by ice hockey players; and (b) to add recently reported Canadian cases to the Canadian Ice Hockey Spinal Injury Registry to determine the effectiveness of prevention efforts. METHODS: The study was a review of questionnaires returned retrospectively by physicians and other sources reporting ice hockey related spinal injuries in Canada. Physicians reported on the mechanism of injury, vertebral level of injury, presence of neurologic deficit, type of event, and type of fracture. RESULTS: Between 1943 and 1999, 271 major spinal injuries were reported in Canadian ice hockey players, of which 49.0% occurred to players 16-20 years of age. Ontario has had a disproportionately large number of injuries compared to some provinces, especially Quebec. Of the spinal cord injuries, 65.8% resulted from colliding with the boards, and 36.6% were due to players being pushed or checked from behind. The recent survey shows that there has been a decline in the number of major spinal cord injuries in Canadian ice hockey, especially those causing paralysis due to checking or pushing from behind. CONCLUSIONS: Impact of the head with the boards after being checked or pushed from behind was the most common mechanism of spinal cord injury. Injury prevention programs are becoming effective in reducing the overall number of injuries, especially those due to checking from behind. Greater awareness of the occurrence and mechanisms of injury through educational programs and rules changes by organized hockey have reduced the annual incidence of catastrophic spinal injuries in Canadian ice hockey.

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; both teacher heads agree on what is shown here.
