AO Spine Clinical Practice Recommendations for the Surgical Management of Acute Traumatic Spinal Cord Injury: Contemporary Concepts
Bibliographic record
Abstract
Study DesignReview of the literature with critical appraisal and clinical recommendations.ObjectiveTo highlight contemporary concepts relating to surgical care for acute traumatic spinal cord injury (SCI) based on recent evidence that may be integrated into clinical practice.MethodsThree recent articles relating to the surgical management of acute traumatic SCI were selected and critically appraised. Clinical practice recommendations were developed and graded as strong or conditional.ResultsArticle 1: Early vs late surgical decompression for central cord syndrome. Strong recommendation to consider early surgery (<24 hours) as an option in patients with ASIA Impairment Scale (AIS) grade C central cord syndrome. Article 2: Extent of decompression in motor complete SCI. Conditional recommendation to consider laminectomy, with or without anterior surgery, to achieve circumferential decompression of the spinal cord. Article 3: Use of intra-operative ultrasound. Conditional recommendation to use ultrasound intra-operatively to confirm the adequacy of surgical decompression.ConclusionsTimely and adequate decompression of the spinal cord are critical priorities in the management of acute traumatic SCI. The importance of timeliness extends to central cord syndrome. Careful consideration and use of operative techniques (e.g., addition of laminectomy) and adjuncts (e.g., intra-operative ultrasound) help achieve safe and adequate decompression of the spinal cord.

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.
