The DRG, located within the dural sheath with only a thin surrounding layer of cerebrospinal fluid (CSF), is a bilateral structure found at every vertebral level and housed within fixed bony vertebral structures (neuroforamen) as it spans the transition from the spinal cord and vertebral column to the periphery. The DRG is a critical structure in sensory transduction and modulation, including pain transmission. This review describes the anatomic and physiologic evidence supporting clinical outcomes. In recent years, the DRG has been recognized as a viable option for neuromodulation therapy electrical stimulation of primary sensory neuron somata may be an elegant solution for treating chronic pain and has generated compelling clinical findings. With an early report in 1949 describing a technique for anesthetic infiltration of the DRG, this structure has been the focus of numerous other pain relief interventions, including dorsal rhizotomy or ganglionectomy, dorsal root entry zone (DREZ) lesioning (an adjacent related neural target), conventional radiofrequency denervation, pulsed radiofrequency, and steroid injection. The role of the dorsal root ganglion (DRG) in chronic pain has long been recognized.
