The Medical Community Roundly Repudiates the Mint Radiofrequency Neurotomy Trials

Thursday, November 30, 2017  

On November 21, 2017, the Spine Intervention Society (SIS) issued a joint statement with 11 other medical societies repudiating the conclusions published in the Dutch study, Effect of Radiofrequency Denervation on Pain Intensity Among Patients with Chronic Low Back Pain: The Mint Randomized Clinical Trials.

This response, which was initiated by SIS, highlights irredeemable flaws in the study’s design, patient selection, procedural technique, and data analysis. If taken at face value, this significantly flawed study may be used to limit coverage for treatments that have been proven beneficial.

The multi-society group also has prepared a resource document for members of the interventional pain community to use when refuting coverage denials based on the Mint Trials. For further assistance, please contact

SIS has been highly active in mobilizing advocacy regarding the Mint article. On August 21, 2017, Dr. Timothy Maus, SIS President, sent a letter to the authors requesting additional details regarding needle placement used in this radiofrequency neurotomy study. As of today, the authors have not responded. Additionally, SIS submitted a letter to the editor of the Journal of the American Medical Association (JAMA) about the Mint Trial’s significant shortcomings, and misrepresentations by the authors of the Society's Guidelines.
