Background: Chronic lumbosacral radicular pain is a common source of radiating leg pain seen in pain management patients. These patients are frequently managed conservatively with multiple modalities including medications, physical therapy, and epidural steroid injections. Radiofrequency has been used to treat chronic radicular pain for over 30 years; however, there is a paucity of literature about the safety and efficacy of repeat radiofrequency lesioning. Objectives: To determine the safety, success rate, and duration of pain relief of repeat pulsed radiofrequency (PRF) and continuous radiofrequency (CRF) lesioning of the dorsal root ganglion (DRG)/ sacral segmental nerves (SN) in patients with chronic lumbosacral radicular pain. Study Design: Retrospective chart review Setting: Outpatient multidisciplinary pain center Methods: Medical record review of patients who were treated with pulsed and continuous radiofrequency lesioning of the lumbar dorsal root ganglia and segmental nerves and who reported initial success were evaluated for recurrence of pain and repeat radiofrequency treatment. Responses to subsequent treatments were compared to initial treatments for success rates, average duration of relief, and adverse neurologic side-effects. Limitations: Retrospective chart review without a control group. Results: Twenty-six women and 24 men were identified who received 50% pain relief or better after PRF and CRF of the lumbar DRG/ sacral SN for lumbosacral radicular pain. The mean age was 62 years (range, 25-86). The mean duration of relief for the 40 patients who had 2 treatments was 4.7 months (range 0-24; Se [standard error] 0.74). Twenty-eight patients had 3 treatments with an average duration of relief of 4.5 months (range 0-19 months; Se 0.74). Twenty patients had 4 treatments with a mean duration of relief of 4.4 months (range 0.5-18; Se 0.95) and 18 patients who had 5 or more treatments received an average duration of relief of 4.3 months (range 0.5-18; Se 1.03). The average duration of relief and success frequency remained constant after each subsequent radiofrequency treatment. Of the 50 total patients, there was only 1 reported complication, specifically, transient thigh numbness which resolved after one week. Conclusions: Repeated pulsed and continuous radiofrequency ablation of the lumbar dorsal root ganglion/segmental nerve shows promise to be a safe and effective long-term palliative management for lumbosacral radicular pain in some patients.

Background: The modified technique, pulsed radiofrequency (PRF) procedure, applied to nervous tissue has been providing anecdotal benefits for the management of chronic and intractable pain conditions. Although PRF has a neuromodulatory effect instead of thermally lesioning nervous tissue, the mechanism underlying the analgesic effect of PRF has not been fully clarified yet. Objectives: To see the changes of electricallyevoked responses of peripheral A-δ and A-β nerve fibers and the analgesic effect induced by PRF. Study Design: Case series. Setting: Inpatient. Methods: This study investigated how dorsal root ganglion (DRG) PRF influenced electricallyevoked responses of peripheral A-δ and A-β nerve fibers at the treated root ganglion dominating areas in five patients with intractable vertebral metastatic pain. Results: DRG PRF provided sound pain relief for patients with intractable vertebral metastatic pain. PRF application at DRGs had a different effect on electrically-evoked responses of peripheral A-δ and A-β nerve fibers at not only the treated root ganglion dominating areas but also the nontreated root ganglion dominating areas far from the treated root ganglion dominating areas in each patient. Limitation: This report is a case series. Conclusions: PRF application at some peripheral nerves could cause drastic neuromodulation throughout the whole body. Key words: Pulsed radiofrequency, dorsal root ganglion block, neuromodulation
