Cervical Spine Dysfunction Following Pediatric Sports-Related Head Trauma
Bibliographic record
Abstract
OBJECTIVE: To examine the prevalence of cervical spine injuries among children and adolescents referred with suspected and diagnosed sports-related concussion (SRC); and evaluate the effect of cervical spine dysfunction (CSD) on physician-documented clinical recovery following SRC. SETTING: A multidisciplinary pediatric concussion program. PARTICIPANTS: A total of 266 patients (6-19 years) referred with suspected SRC. DESIGN: A retrospective cohort study. MAIN MEASURES: CSD defined as neurological symptoms localized to the cervical spine or the presence of neck pain, headache, or dizziness and abnormal cervical spine examination findings; physician-documented clinical recovery. RESULTS: One patient was diagnosed with a T1 compression fracture. Of the 246 patients diagnosed with SRC, 80 (32.5%) met the clinical criteria for CSD including 4 patients with central cord neuropraxia and 1 with a spinal cord injury without radiographic abnormality (SCIWORA). Excluding patients with central cord neuropraxia OR SCIWORA, patients with SRC with CSD took longer to achieve physician-documented clinical recovery (28.5 days vs 17 days, P < .0001) and were 3.95 times more likely to experience delayed physician-documented clinical recovery (>4 weeks postinjury) compared with those without CSD. CONCLUSIONS: Patients with suspected and diagnosed SRC can present with a wide spectrum of coincident cervical spine injuries. Cervical spine dysfunction may be a risk factor for delayed clinical recovery.

How this classification was reachedexpand
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.
