2. Lumbar facet joint radiofrequency denervation therapy for recurrent chronic low back pain: enhanced outcome compared with chemical neurolysis (ethyl alcohol 95% or glycerol 20%)

Abstract

INTRODUCTION: Chronic low back pain is a major source of disability and work productivity loss worldwide. Treatment modalities for back pain due to facet joint arthropathy include chemical neurolysis (Ethyl Alcohol or Glycerol) and radiofrequency denervation of lumbar facet joints. Long-term outcome of these semi-invasive techniques, however, are currently unclear. We hypothesize that radiofrequency denervation is associated with superior pain abolishment and less complications than chemical neurolysis. METHODS: For this prospective follow-up study, we enrolled patients between 01.12.2017 and 01.12.2019. Adult patients with recurrent chronic low back pain, resistant to non-invasive therapy and steroids injections were included. Spinal imaging was performed to exclude alternative diagnoses. Patients were grouped based on treatment modality. The following groups were compared: radiofrequency denervation (Gr. RFD), chemical neurolysis with Ethyl-Alcohol 95% (Gr. EA-95), or Glycerol 20% (Gr. Gly-20). The Core Outcome Measures Index for the back (COMI), World Health Organization (WHO) pain ladder level and VAS (Visual Analog Scale) scores were determined. Furthermore, complications were documented and compared between groups. The outcome was determined pre-interventional, after 6 weeks, 6 and 12 months. RESULTS: A total of 95 patients (60 females and 35 males) with a mean age of 63.7 years were included. Prior to intervention, a mean COMI score of 8.31 and a VAS score of 8.01 were encountered. A total of 30 patients underwent RFD; 35 patients were treated with EA-95; and 35 patients were exposed to Glycerol 20% neurolysis. Subjects had an average WHO pain ladder level of 1.39. No statistically significant differences were found between the three groups. However, upon intervention, patients treated with RFD had significantly lower VAS levels compared to those treated with Ethyl Alcohol after 6 weeks (VAS: 4.33 vs. 6.12, (P<0.05)). Furthermore, after 6 months, bot

Abstract

Fragestellung: Die osteoporotischen Frakturen an der Wirbelsäule führen zu einer pathologischen Kyphosierung damit auch zur Verlagerung des Lots nach ventral. Dies erhöht das Frakturrisiko der benachbarten osteoporotischen Wirbelkörper, was mit einer vertebralen Frakturkaskade enden [zum vollständigen Text gelangen Sie über die oben angegebene URL]
