The Minimally Invasive Lumbar Decompression Procedure: Whimsy or Genuine Invention?
Bibliographic record
Abstract
The article by Levy and Deer in this issue of Pain Medicine ⇓ concerning the safety evaluation of a new technique treating symptomatic lumbar spinal stenosis has many merits, not the least bringing to the reader's attention a new minimally invasive intervention for patients in pain for whom treatment modalities are limited. It also raises several issues symptomatic of the state of clinical research in this country that may negatively affect the development of our specialty, pain medicine. The new technique, known as minimally invasive lumbar decompression (MILD), which reportedly works through a percutaneous remodeling of the ligamentum flavum and the lamina, is done under fluoroscopy. After 510k Food and Drug Administration (FDA) new device approval, several clinical trials have been undertaken in the last 4 years for testing the safety and efficacy of MILD, leading to more than 10 publications, most reporting positive outcomes, with minimal or no complications. Investigators were recruited by the manufacturer, Vertos Medical, and some also became consultants to the company. All followed clinical protocols endorsed by the manufacturer, until this year, when one of them, a professor of neurosurgery at the University of Saskatchewan and a colleague, published his own MILD series in the journal Neurosurgery ⇓. This report stated that 60% of the patients enrolled in the trial required a laminectomy within 18 months and, therefore, concluded “that the failure rate (of MILD) is unacceptably high.” I am not aware of the detailed interaction between this Canadian investigator and …

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.
