The Effectiveness and Procedural Characteristics of the Trident Multi-tined Cannula for Cervical Medial Branch Radiofrequency Ablation Compared to the Conventional Cannula; A Multi-site, Single Blinded, Randomized Controlled Trial.

This trial is testing whether a novel Trident cannula used in cervical medial branch radiofrequency ablation (CMBRFA) offers reduced procedural discomfort, procedure time and radiation exposure, without an inferior change in pain and function compared to conventional cannula. Pain and function measures are collected from 120 patients at 2 weeks, and 3, 6, and 24 months.
