Femoral Nerve Palsy As a Complication of Anterior Iliac Crest Bone Harvest: Report of Two Cases and Review of the Literature
Bibliographic record
Abstract
There are many documented neurological complications of anterior iliac crest bone harvest. Until now, these have included injuries to the iliohypogastric, subcostal and lateral femoral cutaneous nerves. Femoral nerve palsy as a direct surgical complication of anterior iliac crest bone harvest has never been cited in any surgical literature, although it has been reported in deep pelvic and abdominal surgeries in which improper retraction and/or prolonged hyperextension of the hip may have caused a nerve compression syndrome. In addition, surgical patients on antithrombolytic therapy have experienced hemorrhage within the iliacus and iliopsoas muscles, resulting in hematoma and secondary femoral nerve compression. The classic motor and sensory deficits reported in femoral nerve palsies are reduced or absent patellar reflex, weak hip flexion, quadriceps muscle weakness, and anesthesia of the anterior thigh and medial aspect of the leg. Two cases of femoral nerve palsy with different etiologies are presented.

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.
