Dorsal Root Ganglion Stimulation for the Treatment of Chronic Pain Syndromes

The use of Dorsal Root Ganglion (DRG) stimulation has been an important piece of the algorithm in treating pain related to complex regional pain syndrome (CRPS) types 1 and 2, chronic post-surgical pain, nerve injury, peripheral neuropathies, amputation and other causes of nerve injury. Since its first approval in late 2011 in Europe, this technology has evolved and is currently the best evidence driven therapy for many of the conditions noted in this review. The proper use of the device based on patient selection, spinal anatomy, and physician training is important to capture optimal outcomes that are consistent with the peer-reviewed literature. This publication reviews the key points to offering this therapy to appropriate candidates.
