Abstract
RETROSPECTIVE OBSERVATIONAL STUDY TO EVALUATE THEEFFICACY OF RADIOFREQUENCY IN THE TREATMENT OFCHRONIC PHARMACORESISTANT LOW BACK PAIN Corrente A.1, Luxardo N.2, Di Natale A.S.2, Fiore M.1, Pace M.C.1, Passavanti M.B.1, Pirolli R.1, Pota V.1, Sansone P.1, Schettini V.1, Aurilio C.1 1 Department of Women, Child and General and Specialized Surgery, University of Campania Luigi Vanvitelli, Naples, Italy.2 Department of Surgical Sciences, Anesthesia and Intensive Care, University of Turin, Azienda Ospedaliera Cittu00e0 della Salute e della Scienza di Torino, Presidio Molinette, Turin, Italy..Background and aims: Radiofrequency technique is a possible therapeutic strategy for chronic pharmacoresistant low back pain. This study compare the efficacy of continuous (CRF) and pulsed (PRF)radiofrequency for this condition.Methods: 120 patients with chronic pharmacoresistant low back pain were enrolled and treated with radiofrequency from January 2015 to May 2017 at our hospital. From the hospital database, the followingdemographic information was collected: age, sex, etiology of pain, VAS value before treatment (table1). RF type depended on the etiology. The primary outcome was pain intensity (reduction u2265 50% or u2265 3 points ofVAS value) measured 1, 3 and 6 months after the intervention. Data analysis considered three variables: etiology, pain type and origin of pain.Results: Efficacy of CRF in twenty-five spondyloarthrosis and axial nociceptive pain was 96% at 1, 3 months and 88% at 6 month (p<0.01); in spinal stenosis and disc herniation efficacy was greater for axialnociceptive pain (100%, 80%, 80% and 91.6%, 83,3% 83,3% respectively) then neuropathic pain (p<;0,01). Efficacy of PRF in disc herniation was greater for radicular neuropathic pain (85,7% 78,6% 71,4%) as well asin FBSS (66,6% 66,6% 50%), in spinal stenosis (71,4% 57,1% 35,7%) and in spinal stenosis with disc herniation ( 75% 50% 37,5%) (p<0,01), as showed in Table 2.Conclusions: CRF and PRF donu2019t always have the same efficacy. To improve the response to treatment it is important to identify etiology, origin and type of pain for each patient.Conflict of interestThe authors do not have competing interests to declare.
