Femoral Nerve Palsy Following Landmark Based Ilioinguinal-Iliohypogastric Nerve Block: Case Report and Safety Review
Bibliographic record
Abstract
Inguinal hernia repair is one of the most commonly performed procedures in the United States. Ilioinguinal-iliohypogastric nerve blocks are commonly performed for postoperative pain control. Transient femoral nerve palsy is a recognized complication of this block. A 75-year-old male underwent an uncomplicated Lichtenstein repair of an incarcerated right inguinal hernia. An ilioinguinal-iliohypogastric nerve block was performed at the conclusion. Postoperatively, he reported symptomatology of femoral nerve palsy, with full resolution within 8 h. Femoral nerve palsy occurs when anesthetic is infiltrated into the transverse abdominis muscle, allowing for diffusion toward the femoral nerve along contiguous planes of the transverse abdominis-iliacus fascia. Incidence can be as high as 5%. Literature favors ultrasound to landmark-based approaches for improved efficacy and reduced complications. Postoperative protocols for femoral nerve palsy can be implemented with minimal effect on nursing workflow to improve patient safety from the effects of this complication.

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.
