The effect of surgical timing on operative duration and quality of reduction in Type III supracondylar humeral fractures in children
Bibliographic record
Abstract
PURPOSE: To determine the influence of the time from injury to surgery of Type III supracondylar fractures on operative duration and quality of reduction. METHODS: A retrospective review of Type III supracondylar fractures treated by closed reduction and percutaneous pinning over a 3-year period was performed. RESULTS: The subjects were divided into two groups based on the time from injury to surgery (IST): Group 1 (<8 h) 48 subjects and Group 2 (>8 h) 39 subjects. There was no difference in the mean age or gender ratio between the two groups. There were no cases of compartment syndrome or conversion to open reduction in either group. The mean IST was 669 min. The mean IST for Group 1 was 340 min and it was 1,074 min for Group 2. The operative duration for Group 1 was 32.56 min and for Group 2 it was 31.72 min (P = 0.77). There were no significant differences in the quality of reduction. CONCLUSIONS: There was no difference in the operative duration demonstrated between IST <8 h and IST >8 h. This failure to demonstrate a difference should not be interpreted as demonstrating equivalence. This study does not conclude that all displaced supracondylar fractures should be delayed, though it does inform the surgeon that, if compelled to delay surgery, this series did not demonstrate an increased risk of complications, nor a worsened quality of reduction.

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.
