The efficacy of pulsed radiofrequency ablation of the dorsal root ganglion in the setting of failed spinal neuromodulation: A case report

Abstract

Radiofrequency ablation (RFA) is an interventional procedure that has been used to treat chronic back pain for over 50 years; this unique case report demonstrates the effectiveness of pulsed radiofrequency ablation (PRFA) on the dorsal root ganglion (DRG) in the treatment of chronic radicular pain (Russo et al., 2021, J Pain Res, 14, 3897). The RFA provides pain relief by using thermal energy to disrupt peripheral nerves carrying nociceptive signals back to the central nervous system (Abd‐Elsayed et al. 2020, Pain Ther, 9, 709). However, there is a lack of literature about the safety and efficacy of PRFA of the DRG.
