PURPOSE: To guage the protection and efficacy of radiofrequency (RF) ablation of the basivertebral nerve (BVN) for the remedy of continual low again ache (CLBP) in a Meals and Drug Administration accepted Investigational System Exemption trial. The BVN has been proven to innervate endplate nociceptors that are considered a supply of CLBP.
METHODS: A complete of 225 sufferers identified with CLBP have been randomized to both a sham (78 sufferers) or remedy (147 sufferers) intervention. The imply age throughout the examine was 47 years (vary 25-69) and the imply baseline ODI was 42. All sufferers had Sort I or Sort II Modic adjustments of the handled vertebral our bodies. Sufferers have been evaluated preoperatively, and at 2 weeks, 6 weeks and three, 6 and 12 months postoperatively. The first endpoint was the comparative change in ODI from baseline to three months.
RESULTS: At three months, the common ODI within the remedy arm decreased 20.5 factors, as in comparison with a 15.2 level lower within the sham arm (p = zero.019, per-protocol inhabitants). A responder evaluation primarily based on ODI lower ? 10 factors confirmed that 75.6% of sufferers within the remedy arm as in comparison with 55.three% within the sham management arm exhibited a clinically significant enchancment at three months.
CONCLUSION: Sufferers handled with RF ablation of the BVN for CLBP exhibited considerably higher enchancment in ODI at three months and the next responder fee than sham handled controls. BVN ablation represents a possible minimally invasive remedy for the aid of continual low again ache. These slides could be retrieved beneath Digital Supplementary Materials.
