Characteristics of femur fractures in ambulatory young children
Bibliographic record
Abstract
OBJECTIVES: To determine and identify the characteristics and circumstances of femur fractures in ambulatory young children. DESIGN AND SETTING: Retrospective review of 203 ambulatory children, between 1 and 5 years old, presenting with femur fractures to an urban paediatric hospital over a 10-year period. χ(2) And Student's t test were employed for statistical analysis. RESULTS: The mean age was 36.6 months, with 155 (76.2%) being male. The most frequent mechanism of injury was fall from a height (n=62, 30.5%). The highest number of injuries occurred in 2-3-year-olds. The most common history in 1-2-year-olds was stumbling on/over something causing a fall. For 4-5 year olds it was road traffic accidents. Other additional physical findings were infrequent (14.3%) and not suspicious of inflicted injury. Child protective services concluded three of the cases to be likely non-accidental, and four cases were inconclusive but requiring close follow-up. Of these seven children, six occurred in 1-2-year-olds. No distinguishing feature was noted in fracture type or location. CONCLUSIONS: Femur fractures can occur with low velocity injury whether from a short fall or twisting/stumbling injury in young healthy ambulatory children.

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.
