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

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.
