Abstract
Please confirm that an ethics committee approval has been applied for or granted: Yes: I’m uploading the Ethics Committee Approval as a PDF file with this abstract submission Background and Aims Chronic hip pain presents a significant challenge in pain management. This study aimed to compare the efficacy of three interventions: radiofrequency thermocoagulation(RFT), intra-articular steroid injection(IAI), and PENG block, in alleviating pain and improving functional capacity among chronic hip pain patients. Methods A prospective randomized controlled study involved 57 patients. After ethical approval and patient consent, they were randomly assigned to three treatment groups: conventional RFT (Group1), IAI (Group2), and PENG block(Group3). Pain intensity was assessed using the Numerical Rating Scale (NRS) pre-procedure and at 2 hours, 1 month, and 3 months post-procedure. Functional capacity was evaluated using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) scale at baseline, and at 1 and 3 months post-procedure. Results At 2 hours post-procedure, all groups exhibited a significant reduction in NRS scores compared to baseline, with no significant inter-group differences. By 1 month, NRS and WOMAC scores in Groups1 and 2 were significantly lower than baseline, while Group3 showed comparable NRS scores but higher WOMAC scores. At 3 months, Group1 demonstrated significantly lower NRS and WOMAC scores compared to baseline and other groups. Group2 maintained reduced NRS and WOMAC scores, while Group3 showed no significant improvement. Complications related to the procedures were not observed. Conclusions Our findings suggest that PENG block, RFT, and IAI effectively managed acute pain in chronic hip pain patients. While IAI and RFT were effective in managing chronic pain up to the first month, only RFT remained effective at the 3-month follow-up. PENG block did not demonstrate effectiveness in chronic follow-ups.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
