BackgroundChronic low back pain is a leading cause of disability worldwide and its pathophysiology remains poorly understood, a problem exacerbated by the heterogeneity of the patient population with chronic low back pain. Although the intervertebral discs are often implicated in chronic low back pain, studies have demonstrated strong innervation of the vertebral endplates by the basivertebral nerve, therefore making it a possible target for ablation in the treatment of vertebrogenic chronic low back pain.ObjectivesThis work reviews the current evidence for the efficacy and safety of basivertebral nerve ablation as a treatment modality for chronic low back pain, and discusses the possible study biases and gaps in the current knowledge to provide insight on future research.Study DesignThe authors registered with the Center for Open Sciences and followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews  (PRISMA-ScR).SettingA private clinic.MethodsThis study was performed in accordance with the following 5-stage methodological framework for scoping reviews: (i) identifying the research question; (ii) identifying relevant studies; (iii) selecting studies; (iv) charting the data; and (v) collating, summarizing and reporting the results. Three databases (PubMed, Web of Science, Embase) were searched using the keywords "basivertebral", "nerve", and "ablation".ResultsFrom March 2002 to March 2022, a total of 47 articles were identified, of which 12 were included in this scoping review, based on the exclusion criteria described in Table 1.LimitationsThe limitations found were: • A very specific chronic pain population is typically utilized for this intervention. The inclusion criteria leave many who experience chronic low back pain ineligible for the procedure. • Study demographics need to be more diversified to truly represent the chronic low back pain population.• There is a lack of true control groups due to high crossover rates in published studies.• Very few high-level or long-term studies have been published.• Funding for many of the studies published on the subject is industry-led (Table 6). With an already limited amount of published research, a need for out-of-industry funding is required to avoid any possibility of bias.ConclusionsCurrent research has shown that basivertebral nerve ablation might be a promising treatment for chronic low back pain in patients exhibiting Modic type 1 or 2 endplate changes, while additional research on the association between Modic changes and low back pain is still needed to gain widespread use and acceptance of this new treatment modality. The introduction of new devices and a larger number of independent studies would greatly enhance the confidence in the outcomes reported with this treatment modality in order to ultimately benefit patients, clinicians, and society.
