Continuous Infragluteal Sciatic Nerve Block for Postoperative Pain Control After Total Ankle Arthroplasty
Bibliographic record
Abstract
Continuous peripheral nerve blocks (CPNB) for postoperative pain control are being used more frequently for total ankle arthroplasty. The purpose of this study was to compare the amount of opioid analgesia used in patients with an infragluteal CPNB to that of patients with no CPNB for postoperative pain management after total ankle replacement. A retrospective cohort study was performed on 78 consecutive patients who had a total ankle arthroplasty from October 2006 to June 2013. The primary outcome measure was opioid analgesia use in the first 48 hours postoperatively. The mean postoperative narcotic use in oral morphine equivalents was 64.6 mg in the CPNB group compared to 129.6 mg in the no CPNB group (P < .001). Using an infragluteal CPNB as a means of postoperative pain control in patients undergoing a total ankle replacement is associated with significantly decreased opioid use compared to patients receiving no CPNB. LEVELS OF EVIDENCE: Therapeutic, Level IV, case series.

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.
