Sudden Quadriplegia after Acute Cervical Disc Herniation
Bibliographic record
Abstract
BACKGROUND: Acute neurological deterioration secondary to cervical disc herniation not related to external trauma is very rare, with only six published reports to date. In most cases, acute symptoms were due to progression of disc herniation in the presence of pre-existing spinal canal stenosis. CASE REPORT: A 42-year-old man developed weakness and numbness in his arms and legs immediately following a sneeze. On physical examination he had upper motor neuron signs that progressed over a few hours to a complete C5 quadriplegia. An emergent magnetic resonance imaging study revealed a massive C4/5 disc herniation. He underwent emergency anterior cervical discectomy and fusion. Postoperatively, the patient remained quadriplegic. Eighteen days later, while receiving rehabilitation therapy, he expired secondary to a pulmonary embolus. Autopsy confirmed complete surgical decompression of the spinal cord. CONCLUSIONS: Our case demonstrates that acute quadriplegia secondary to cervical disc herniation may occur without a history of myelopathy or spinal canal stenosis after an event as benign as a sneeze.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
