Abstract
The pedicled posterior interosseous artery flap is a reliable and effective option for reconstructing soft tissue defects in the upper extremity. Commonly described in a retrograde fashion for distal defects, its antegrade counterpart is less frequently reported, particularly in relation to elbow reconstructions. Additionally, there are few and less detailed descriptions on how to safely and correctly identify the posterior interosseous nerve (PIN) in the harvest. The current case describes the use of the pedicled antegrade posterior interosseous artery flap to resurface a complex elbow wound with exposed triceps tendon, exposed ulnar nerve and an open elbow joint. We present a detailed step-by-step harvest with the additional anatomical description of the topography of the PIN branches relative to the PIA pedicle.

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 it
