Minimally invasive cervical laminectomy for spondylotic myelopathy in medically fragile patients
Bibliographic record
Abstract
BACKGROUND: Cervical spondylotic myelopathy often affects elderly and fragile patients who are not optimal candidates for major surgical procedures. Here, we report patients previously judged not suitable for cervical surgery, who were successfully treated with minimally invasive (MI) cervical decompressions without complications. METHODS: Retrospectively, we reviewed medically fragile patients (e.g., too many comorbidities), previously deemed unsuitable for surgery who successfully tolerated MI cervical decompressions. The accompanying preoperative comorbidities, surgical risks, complications, and neurological outcomes were assessed. RESULTS: Three male patients, with a mean age of 73 years, exhibited an average preoperative modified Japanese Orthopedic Association (mJOA) score of 8. The preoperative Charlson comorbidity indices, the Elixhauser comorbidity indices (respectively averaging 5.7 and 5.7 points, the preoperative Edmonton fragility index (average 12 points), and national surgical quality improvement program risks were calculated. Surgical times averaged 185 min and patients were followed for an average of 11.3 months. No patient had any immediate or delayed postoperative complications. The length of hospital stay was 1 day for each patient. The postoperative mJOA scores averaged 11, which was clinically significant. Further, the postoperative magnetic resonance imaging obtained approximately 3 months postoperative demonstrated adequate cord decompression. CONCLUSION: Medically fragile patients with significant cervical spondylotic myelopathy but major comorbidities precluding major surgery successfully underwent MI cervical decompressions.

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; a candidate call from one teacher head, not a consensus.
