Monitoring and Comparison of the Therapeutic Effect of the Three Miniinvasive Low Back Pain Treatment Methods (Pulsed Radiofrequency Modulation, Oxygen-ozone Therapy and Periradicular Therapy) in Patients with Algic Radicular Syndrome L5 or S1 over a Period of One Year after Procedure

Aim: To compare the therapeutic efficacy of the three minimally invasive methods (PRF, KOT, PRT) in patients with chronic (more than 3 months lasting) unilateral radicular syndrome L5 or S1. The hypothesis: PRF and KOT are more effective than PRT in the treatment of chronic radicular pain. Material and methods: Prospective, randomized, unilaterally blinded, monocentric study. All patients underwent one of the procedures, navigated by CT. Two questionnaires: PainDETECT and Oswestry disability questionnaire were used to measure of the outcome - before treatment, immediately after and at the of 3th, 6th and 12th month after. Evaluated parameters: quantity of pain (VAS), neuropathic component of pain (NB), disability (ODI), character of pain (CHB), analgesic consumption (an), physiotherapy (re). Results: Group of 178 patients (115 women, 63 men, median age 56, BMI 27,5). (PRF 57, KOT 69, PRT 52). VAS was immediately reduced after procedures, mainly in PRT group with statistic significance in comparison - KOT to PRT (p = 0,0152). By the end of 3rd and 6th month after, the VAS values in all methods were similar, still lower than before treatment. PRT showed the best analgesic effect on NB, with statistical significance between PRT and PRF after 3rd and 6th month (p = 0,0457 and 0,0108, respectively)...
