In the last 20 years, we have seen the flourishing of multiple treatments targeting the dorsal root ganglion (DRG) for pain. However, there is concern regarding the variation in the location of the DRG, which could influence the long-term clinical outcomes. The aim of this work was to determine the exact position of the DRG in the spine and propose a pre-surgical planning. ⋯ Percutaneous treatments for chronic pain directed at the DRG are effective. Clinical outcomes depend of good preoperative planning that allows for optimizing its effects. We propose a DRG morphology evaluation scale useful for the planning process prior to any treatment directed at the ganglion.
