Abstract
Carpal tunnel syndrome is a common condition in adults with an estimated prevalence of up to 5% in the general population. The presence of a persistent median artery is an important consideration for plastic and orthopedic surgeons who frequently perform carpal tunnel release. This artery may persist into adulthood and constitute a significant supply of blood to the hand, sometimes compressing the median nerve. In this case series, we describe the prevalence of the persistent median artery identified intraoperatively in Polish subjects undergoing surgical open carpal tunnel release. The data regarding the prevalence of persistent median artery were retroactively collected postoperatively from the standard surgical protocols. Persistent median artery was identified in 36 out of 1285 operated hands (2.8%). The observed PMAs were identified in 15 (2.0%) cases out of 750 right upper limbs and in 21 (3.9%) cases out of the 535 left upper limbs. Persistent median artery can be present in the operating field of any surgeon that performs carpal tunnel release and any other surgical procedures in the wrist region. Therefore awareness of its presence is crucial to minimize intraoperative complications such as bleeding or digital ischemia.

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
