The effectiveness and procedural characteristics of cervical (neck) facet radiofrequency ablation (RFA) performed with a perpendicular approach using the the multitined Trident cannula is examined in this study.
Cervical facet joint RFA using the Trident cannula resulted in significant improvements in pain and disability. The procedure was shorter and required less fluoroscopy time compared to cervical RFA performed with the traditional monopolar cannula using a posterior approach.
Cervical facet RFA, using a multi-tined cannula using a perpendicular/lateral approach to the medial branch nerves is less demanding for the operator and patient, and potentially safer than the traditional parallel/posterior approach. The Trident multi-tined cannula is well designed for this approach. However, its effectiveness and procedural characteristics had never previously been studied.
