Critical sites of entrapment of the posterior division of the obturator nerve
Bibliographic record
Abstract
Methods: This study was carried out on 28 cadavers of both sexes and of different ages using the traditional anatomical macro- and micro-dissection. Summary of results: In the current anatomic study special attention was given to the relationship of the posterior division of the obturator nerve with respect to surrounding structures that may, in certain conditions, constitute critical sites of entrapment. These entrapment sites are as follows: The obturator canal, where the posterior division is surrounded by the obturator vessels, nerve to obturator externus muscle, anterior division of the obturator nerve, and adipose tissue. The fibro-muscular canal formed by the obturator membrane and the posterior surface of the obturator externus muscle. The muscular tunnel where the posterior division perforates the obturator externus muscle. The distinct fascial plane situated deep to the pectineus and adductor brevis muscles and superficial to the obturator externus and proximal one third of the adductor magnus muscles. Conclusion: Knowledge of the sites of entrapment of the posterior division of the obturator nerve can aid in the diagnosis of peripheral neuropathies, and contribute to safe and more effective surgical procedures.

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.
