A Unique Case of Bilateral High Ulnar Nerve Laceration
Bibliographic record
Abstract
High ulnar nerve injuries are now commonly treated with a distal nerve transfer, in which the anterior interosseuos nerve to pronator quadratus is coapted to the deep ulnar nerve motor branch. Herein, the authors describe a case of bilateral ulnar nerve laceration that provides an opportunity to directly compare two operative techniques on different extremities of the same patient. The patient sustained bilateral ulnar nerve injuries 6 cm superior to the medial epicondyle. The right ulnar nerve was proximally repaired with primary neurorraphy and a distal motor nerve transfer. The left ulnar nerve underwent primary nuerorraphy without a nerve transfer because the median nerve was mistakenly tied off to control bleeding. Physical examination and nerve conduction studies two years postsurgical intervention demonstrated an undeniable difference in cosmesis and function. The clinical findings suggest a superior result with a combined primary neurorraphy and a distal nerve transfer compared with a primary neurorraphy alone.

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.
