Implication

Cohort study demonstrates sustained pain relief and reduced opioid use in facet joint pain patients, indicating three-tined radiofrequency ablation simplifies effective treatment.

Key Points

To assess long-term clinical outcomes of three-tined lumbar medial branch radiofrequency ablation utilizing a perpendicular approach for chronic facet joint pain.
Reviewed electronic medical records of patients who received three-tined perpendicular lumbar medial branch radiofrequency ablation between 2022 and 2024.
Assessed outcomes at ≥6 months post-procedure via standardized telephone surveys tracking numerical rating scale pain scores, patient global impression of change, and opioid use.
Evaluated predictors of treatment response using Poisson regression.
Approximately half of patients achieved ≥50% numerical rating scale pain reduction for up to 12 months.
At average follow-up, 53.5% (95% CI: 42.0–64.6) of patients reported patient global impression of change scores ≥6 ('much improved' or better).
Opioid analgesic use fell significantly, achieving a 75% cessation rate among baseline users, with advanced age, repeat procedures, and shorter follow-up predicting treatment success.
