Effect of Percutaneous Vertebroplasty in Chronic Osteoporotic Compression Fracture of Thoracic and Lumbar Vertebra
Bibliographic record
Abstract
Objective: This study was conducted to assess the effect of percutaneous vertebroplasty in the patients with chronic osteoporotic compression fracture at the thoracic and the lumbar vertebra. Method: Twelve patients with chronic osteoporotic compression fracture of thoracic and lumbar vertebra were engaged in this study. Treated levels were from the ninth thoracic vertebra to the fifth lumbar vertebra. Effects were assessed on the first day, 1 month after treatment and the last follow up (average 164 days after vertebroplasty; range 60 days to 302 days) by visual analogue scale (VAS), McGill pain questionnaire (MPQ), and compression ratio of vertebral body. Complication rate was assessed. Results: Significant improvement by VAS and MPQ was noticed on the first day, 1 month after treatment and the last follow up. Further vertebral height loss was not noticed on follow-up. Conclusion: Percutaneous vertebroplasty can be an effective treatment method in patients with chronic back pain due to osteoporotic compression fracture at the thoracic and the lumbar vertebra.

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.
