CT angiography-guided single-stage release of adjacent webspaces in non-Apert syndactyly
Bibliographic record
Abstract
UNLABELLED: We describe the CT angiography protocol and surgical technique utilized at our institution for single-stage release of adjacent web-spaces in non-Apert syndactyly. In a series of seven consecutive hands we analyse syndactyly anatomy, CT angiographic findings, operative details, and complications. Outcomes were assessed with a functional activity evaluation, range of motion, and a parental visual analogue scale. Seven affected hands in four patients underwent single-stage release of adjacent webspaces. In all cases, the CT angiogram correctly predicted the presence of at least one artery supplying each digit. There were no cases of digital ischemia or loss. Angiographically guided, single-stage release of adjacent webspaces is technically feasible and benefits patients by reducing the number of surgical stages and allowing complete release to be achieved at an earlier age compared with the standard multi-stage approach. LEVEL OF EVIDENCE: IV.

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.
