“…DRG neurostimulation has been shown to effectively treat discrete areas of pain, such as the groin and foot, which are typically more difficult to treat with traditional SCS without causing discomfort in non‐painful regions . In these specific areas, our pooled analysis showed an 80% responder rate at one year.…”

Introduction Since it became available in the mid‐2010s, dorsal root ganglion (DRG) stimulation has become part of the armamentarium to treat chronic pain. To date, one randomized controlled trial, and several studies of moderate sample size and various etiologies have been published on this topic. We conducted a pooled analysis to investigate the generalizability of individual studies and to identify differences in outcome between chronic pain etiologic subgroups and/or pain location. Materials and Methods One prospective, randomized comparative trial and six prospective, single‐arm, observational studies were identified that met pre‐defined acceptance criteria. Pain scores and patient‐reported outcome (PRO) measures were weighted by study sample sizes and pooled. Safety data are reported in aggregate form. Results Our analysis included 217 patients with a permanent implant at 12‐month follow‐up. Analysis of pooled data showed an overall weighted mean pain score of 3.4, with 63% of patients reporting ≥50% pain relief. Effectiveness sub‐analyses in CRPS‐I, causalgia, and back pain resulted in a mean reduction in pain intensity of 4.9, 4.6, and 3.9 points, respectively. Our pooled analysis showed a pain score for primary affected region ranging from 1.7 (groin) to 3.0 (buttocks) and responder rates of 80% for foot and groin, 75% for leg, and 70% for back. A substantial improvement in all PROs was observed at 12 months. The most commonly reported procedural or device complications were pain at the IPG pocket site, lead fracture, lead migration, and infection. Conclusions DRG stimulation is an effective and safe therapy for various etiologies of chronic pain.

“…In addition, several small case series also have reported outcomes with DRG stimulation, including for complex regional pain syndrome (CRPS) of the lower limbs ( N = 11) , CRPS of the knee ( N = 1) , and groin pain ( N = 3 and N = 29) . In these case series, the trial‐to‐permanent ratio was between 73% and 86% , and average pain relief ranged between 62% and 100% with follow‐ups of a year or less .…”

“…Target identification is usually accomplished using established dermatomal maps . Thus, groin pain is usually treated with L1 and/or L2 stimulation; knee pain by L3 and/or L4 stimulation, and foot pain by L4, L5, and/or S1 stimulation.…”
