Dorsal root ganglion stimulation (DRG‐S) has emerged as a treatment for complex regional pain syndrome (CRPS) of the lower extremities, and recent small studies are demonstrating its potential efficacy in pain syndromes that are traditionally considered nociceptive in nature, such as axial low back pain. While improvements in neuromodulation technology have been substantial over the past decade, with DRG‐S systems patients occasionally require additional interventional pain treatments for treatment of pain from other sources. Radiofrequency ablation (RFA) of medial branch nerves innervating the facet joints is an accepted therapy for pain arising from the facet joints.

腰椎射频消融干扰S1背根神经节刺激系统：两种情况的经验。

背根神经节刺激（DRG-S）已成为治疗下肢复杂区域疼痛综合征（CRPS）的一种疗法，最近的小型研究表明其在传统上被认为具有伤害性的疼痛综合征（如轴痛）中具有潜在的疗效腰背疼痛。在过去的十年中，尽管神经调节技术取得了长足的进步，但使用DRG-S系统的患者偶尔需要进行其他介入性疼痛治疗，以治疗其他来源的疼痛。支配小关节的内侧分支神经的射频消融（RFA）是治疗小关节引起的疼痛的公认方法。
