OBJECTIVE: to evaluate the effectiveness of pulsate radio-frequency on L2 dorsal root ganglion for chronic discogenic low back pain. Of L2 in the treatment of the patient with discogenic low back pain. METHODS: Between January 2004 and July 2007, 50 patients with diagnosis of low back discogenic pain were retrospectively assessed based on physical examination, magnetic resonance imaging findings and selective L2 dorsal root ganglion diagnostic block, and then submitted to pulsed radiofrequency on L2 dorsal root ganglion, and evaluated after a minimum follow-up of 12 months. Pain was evaluated by the visual analog scale. RESULTS: Statistical analysis showed significant improvement of pain intensity (p<0.001) after a minimum 12-month follow-up period. CONCLUSION: Pulsed radiofrequency on L2 dorsal root ganglion is an effective, non-specific therapeutic method for low back discogenic pain, despite the short follow-up period of this series.
