ObjectiveDetermine the relative effectiveness and safety profiles of percutaneous and minimally invasive interventions for chronic low back pain.MethodsA systematic search was performed for randomized controlled trials published in the past 20 years reporting on radiofrequency ablation of the basivertebral, disk annulus and facet nerve structures, steroid injection of the disk, facet joint, and medial branch, biological therapies, and multifidus muscle stimulation. Outcomes evaluated included Visual Analog Scale (VAS) pain scores, Oswestry Disability Index (ODI) scores, quality of life (SF-36 and EQ-5D) scores, and serious adverse event (SAE) rates. Basivertebral nerve (BVN) ablation was chosen as the subject of comparison to all other therapies using a random-effects meta-analysis.ResultsTwenty-seven studies were included. BVN ablation was found to provide statistically significant improvements in VAS and ODI scores for 6-, 12- and 24-month follow-up ( P ≤0.05). Biological therapy and multifidus muscle stimulation were the only 2 treatments with both VAS and ODI outcomes not significantly different from BVN ablation at 6-, 12-, and 24-month follow-up. All outcomes found to be statistically significant represented inferior results to those of BVN ablation. Insufficient data precluded meaningful comparisons of SF-36 and EQ-5D scores. The SAE rates for all therapies and all reported time points were not significantly different from BVN ablation except for biological therapy and multifidus muscle stimulation at the 6-month follow-up.ConclusionsBVN ablation, biological therapy, and multifidus stimulation all provide significant, durable improvements in both pain and disability compared with other interventions, which provided only short-term pain relief. Studies on BVN ablation reported no SAEs, a significantly better result than for studies of biological therapy and multifidus stimulation.Copyright © 2023 The Author(s).
