Objective: Evaluate clinical outcome of dorsal root ganglia (DRG) pulsed radiofrequency (PRF) treatment in neuropathic pain of patients with radiculopathy regarding improvement of pain and degree of patients' satisfaction. Method: Forty-five procedures in cervical and lumbossacral spine. Data collected by phone call interviews (independent researcher). Evaluation done after one month and at minimum three months follow-up. Analyzed data included objective and subjective improvement, and degree of satisfaction. Results: Outcome much better in 31%, 36% better, 24% unchanged, 9% worse. At initial evaluation, relief was rated: 24% excellent, 16% good, 27% moderate, 33% poor. At late evaluation, 27% excellent, 18% good, 7% moderate, 49% poor. Degree of satisfaction was high (82% of patients reported they certainly or probably would repeat the procedure). Conclusion: PRF was effective and safe in selected patients. Most patients were satisfied and would repeat/recommend the procedure.
