PurposeA prospective, single-arm, open-label study to evaluate the effectiveness of intraosseous radio frequency (RF) ablation of the basivertebral nerve (BVN) for the treatment of vertebrogenic-related chronic low back pain (CLBP) in typical spine practice settings using permissive criteria for study inclusion.MethodsConsecutive patients with CLBP of at least 6 months duration and with Modic Type 1 or 2 vertebral endplate changes between L3 and S1 were treated with RF ablation of the BVN in up to four vertebral bodies. The primary endpoint was patient-reported change in Oswestry Disability Index (ODI) from baseline to 3 months post-procedure. Secondary outcome measures included change in visual analog scale (VAS), SF-36, EQ-5D-5L, and responder rates.ResultsMedian age was 45 years; baseline ODI was 48.5; VAS was 6.36. Seventy-five percent (75%) of the study patients reported LBP symptoms for ≥ 5 years; 25% were actively using opioids; and 61% were previously treated with injections. Mean change in ODI at 3 months posttreatment was - 30.07 +14.52 points (p < 0.0001); mean change in VAS was - 3.50 + 2.33 (p < 0.0001). Ninety-three percent (93%) of patients achieved a ≥ 10-point improvement in ODI, and 75% reported ≥ 20-point improvement.ConclusionsMinimally invasive RF ablation of the BVN demonstrated a significant improvement in pain and function in this population of real-world patients with chronic vertebrogenic-related LBP.
