The application of pulsed radiofrequency to the lumbar sympathetic chain to relief sympatheti-cally maintained pain in the complex therapy of chronic regional pain syndrome (CRPS) is a promising treatment option. Although it is frequently used in clinical practice, there is almost no evidence available.The treatment of 15 patients with lower limb CRPS was prospectively evaluated in a routine clinical setting. Follow-ups were recorded at 6 weeks and 6 months after the intervention. Those patients with a clinically diagnosed CRPS, who experiencing pain relief to sympathetic blocks with local anaesthetics, received percutaneous lumbar sympathicolysis with pulsed radiofrequency. Various pain scores, quality of life, impairment of daily activities and satisfaction were assessed with Numeric Rating Scales. A significant pain relief of 15% at 6 weeks and 13% at 6 months and an improvement in some of the disability scores were achieved. The patients were very satisfied with the procedure at the 6 weeks (7.5 (2.2) p<0.001) and the 6 months follow-up (7.8 (3.2) p<0.001). The improvement in the quality of life was distinct but just missed the significance level. Pulsed radiofrequency applied to the lumbar sympathetic chain in patients with lower limb CRPS and sympathetically maintained pain offers a significant pain relief and an improvement in disability for at least 6 weeks.
