P.146 Anterior spinal cord herniation following an anterior cervical discectomy and fusion: case report
Bibliographic record
Abstract
Background: Anterior cervical discectomy and fusion (ACDF) and corpectomy is one of the most common spinal operations performed worldwide to treat herniated discs causing anterior spinal cord compression , cervical spondylosis, fractures, and neoplasms, with the routine complications. There have been just a few known cases of anterior spinal cord herniation following multilevel anterior ACDF and corpectomy fusion cases. Methods: A 53-year-old male initially presented with a 3 year’s duration of increasing myelopathy with history of Anterior cervical surgery C3 -5. About 10 years prior he was not able to walk had difficulty to use his hand. (he have nice images on MRI scan of typical spinal herniation)Results: Patient was initially treated medically with utilizing analgesia and physiotherapy and gradually deteriorated over two year. Patient revision surgery and release of spinal cord with intra-operative durotomy and release of the spinal cord. He had only mild improvement in hand function, No change in legs function post operatively. Conclusions: The occurrence of spinal cord herniation through a prior ACDF or Corpectomy defect must be considered when patients present with recurrent myelopathy following anterior cervical surgery. Early investigation and early release surgery can improve the outcome for these group of patients

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.
