Abstract
BACKGROUND: Over 70% of Canadian carpal tunnel syndrome (CTS) operations are performed outside of the main operating room (OR) with field sterility and surgeon-administered pure local anesthesia [LeBlanc et al., Hand 2(4):173-8, 14]. Is main OR sterility necessary to avoid infection for this operation? This study evaluates the infection rate in carpal tunnel release (CTR) using minor procedure room field sterility. METHODS: This is a multicenter prospective study reporting the rate of infection in CTR performed in minor procedure room setting using field sterility. Field sterility means prepping of the hand with iodine or chlorhexidine, equivalent of a single drape, and a sterile tray with modest instruments. Sterile gloves and masks are used, but surgeons are not gowned. No prophylactic antibiotics are given. RESULTS: One thousand five hundred four consecutive CTS cases were collected from January 2008 to January 2010. Six superficial infections were reported and four of those patients received oral antibiotics. No deep postoperative wound infection was encountered, and no patient required admission to hospital, incision and drainage, or intravenous antibiotics. CONCLUSIONS: A superficial infection rate of 0.4% and a deep infection rate of 0% following CTR using field sterility confirm the low incidence of postoperative wound infection using field sterility. This supports the safety and low incidence of postoperative wound infection in CTR using minor procedure field sterility without prophylactic antibiotics. The higher monetary and environmental costs of main OR sterility are not justified on the basis of infection for CTR cases.

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
