Abstract
Introduction: Lumbar disc herniation (LDH) is a leading cause of radiculopathy and low back pain, contributing significantly to global disability. Management strategies include conservative and surgical treatments, but clinical decision-making lacks standardization, particularly in surgical indications, timing, and criteria for transitioning from conservative management. Research question: What are the surgical indications, criteria for transitioning from conservative to surgical management in LDH, and what role do motor deficits play? Material and methods: Following PRISMA guidelines, a systematic search across major databases identified 20 studies. Risk of bias was assessed using the Newcastle Ottawa Scale and RoB 1 tools. A qualitative synthesis was conducted, and the Index of Qualitative Variation (IQV) quantified variability in indications. Results: Among the studies that reported specific indications, imaging-confirmed nerve root compression (reported in 18/20 studies) and severe/refractory pain (reported in 17/20 studies) were the most consistent indications, while thresholds for sensory deficits (reported in 8/20 studies) varied widely. Early surgery (48 h-6 weeks) was associated with superior recovery, particularly for mild/moderate motor deficits graded ≤ MRC 3/4, achieving >90 % recovery rates. Delayed surgery (>6 weeks) resulted in prolonged symptoms and poorer outcomes, especially in severe cases. Transition criteria included a patient-specific combination of failure of conservative therapy (n = 12) after a most frequently 4-6-week trial, neurological progression, and worsening imaging findings. Significant heterogeneity was observed in thresholds for motor and sensory deficits, with high IQV scores for definitions of conservative treatment failure (IQV = 0.96) and motor deficit (IQV = 0.96). Discussion and conclusion: Significant heterogeneity in surgical indications, timing, and decision-making highlights the urgent need for standardized, evidence-based guidelines to optimize clinical decisions and improve outcomes in LDH management.

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 it
