Sonographic Assessment of a Bifid Median Nerve and Median Artery in Carpal Tunnel Syndrome
Bibliographic record
Abstract
Numerous variants of the median nerve in the carpal tunnel, such as a bifid morphology, have been reported1. The prevalence of bifid median nerve with or without a persistent median artery continues to be intriguing. However, a bifid nerve has been observed in patients with carpal tunnel syndrome (CTS). The nerve compression via trauma, dilatation, thrombosis, and arterial calcification is disputed2. An ultrasound scan in longitudinal and transverse planes at the volar aspect of both wrists, at the level of the carpal tunnel, was obtained in 3 patients. Scans were performed using a GE Logiq e ultrasound machine equipped with a broadband linear probe from 8 to 13 MHz. The first case, an 80-year-old woman with history of osteoarthritis of the hands, presented with tingling and numbness at the median nerve area in the right …

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.
