Objective: To evaluate the safety of facet-dependent radiofrequency thermolysis for the treat-ment of chronic thoracolumbar pain. Materials and methods: A retrospective analysis was performed on 12 patients with chronic thoracolumbar pain of facet type, who had previously undergone a radicular blockage using computed tomography (CT), in the period between July 2013 and July 2014. Inmediateand delayed complications where assessed. Improvement of symptoms was also assessed, both directly (visual analogue scale), and indirectly (reduction in pain relief medication). Results: Self-limited early complications were noted in 20% of the patients. No late nor serious complications were reported. Three months after the procedure was performed, pain relief was observed in 83% of the cases (n= 10), with absolute reduction in pain relief medication in 25% (n = 3) of the patients, and a partial reduction in 58% (n = 7). Discussion: In spite of the reduced number of patients in our study, the results were similar to other publications with larger populations in regard to safety and procedure success. Improvement was not only reflected by the reporting of reduced pain, but it was also observed in a reduced intake of pain relief medications. Conclusión: Our study shows that facet-dependent radiofrequency thermolysis is a safe and useful method, with low complication rates, that can be managed on an outpatient basis.
