Chronic intractable lumbosacral radicular pain, is there a remedy? Pulsed radiofrequency treatment and volumetric modifications of the lumbar dorsal root ganglia

AbstractPurposeEvaluation of clinical and radiological effects of the therapeutic outcome of CT-guided pulsed radiofrequency (PRF) treatment adjacent to the lumbar dorsal root ganglion (DRG) for patients with chronic intractable lumbosacral radicular pain in a single-center prospective longitudinal study in order to evaluate predictive factors of safety and therapeutic success.Materials and methodsThirty patients, from 2016 to 2018, were enrolled (age: 42 –80 aa, 66.7% men and 33.3% females) with low back pain, lumbosciatalgia and/or lumbocruralgia, resistant to previous medical and physical treatments for a period not

Purpose of review To update the recent development of spinal cord stimulation (SCS) technology in the management of chronic pain. Recent Findings Efficacy of SCS therapy has been significantly improved by the recent development of high frequency (HF-10 kHz) stimulation, burst stimulation, and dorsal root ganglion (DRG) stimulation. A few latest SCS modalities are in clinical trial. New approaches to guide lead placement and advances in surgical lead are introduced. Summary HF-10 SCS is free of paresthesia and associated with significantly better coverage of axial lower back pain. Burst stimulation invokes minimal...
