NCT07433634

Brief Summary

Basivertebral nerve ablation (BVNA) is a minimally invasive procedure approved for vertebrogenic low back pain. While early studies support its efficacy, real-world evidence is still evolving, particularly regarding the trajectory of pain relief and functional improvement over time, and predictors of clinical response. This study aims to evaluate clinical outcomes longitudinally following BVNA and identify baseline predictors of response.

Outcome Measures

Primary Outcomes (1)

  • Percentage of participants achieving clinical response

    Clinical response defined as a ≥50% reduction in pain intensity from baseline as measured by the Visual Analog Scale (VAS) or a ≥15-point improvement in the Oswestry Disability Index (ODI) score

    2 years

Secondary Outcomes (4)

  • Change in PROMIS-7 Global Health Score

    2 years

  • Percentage of participants with incresed physical activity assessed using Physical Activity Vital Sign (PAVS)

    2 years

  • Incidence of spine-related interventions

    2 years

  • Patient Global Impression of Change (PGIC) score

    2 years

Interventions

Participants underwent fluoroscopically guided intraosseous basivertebral nerve ablation (BVNA) using the Intracept® System (Boston Scientific, MA, USA) targeting MRI-confirmed Modic type 1 or 2 vertebral endplate changes. Procedures were performed under general anesthesia via a transpedicular or parapedicular approach with biplanar fluoroscopic confirmation of probe placement at the basivertebral foramen (30-50% vertebral body depth, midline AP position). Thermal radiofrequency ablation was delivered using either 75°C for 7 minutes (targeted lesion) or 85°C for 15 minutes (expanded lesion), selected based on intraoperative probe proximity to the intended target to optimize nerve capture. Only levels with imaging-confirmed Modic changes were treated. Weekly patient-reported outcomes were collected for 8, 12, 24 , 48 through 98 weeks.

  • Capable of participating in weekly virtual/telephone follow-up for 8 weeks and in- person or remote follow-up at 3 and 6 months through 2 years

You may not qualify if:

  • Prior spinal neuromodulation therapy (e.g., spinal cord stimulation or intrathecal pump) within the past 6 months
  • Active substance use disorder or uncontrolled psychiatric illness that may interfere with participation
  • Cognitive impairment limiting ability to complete surveys or provide informed consent
  • Pregnancy
  • Incarceration or current status as a prisoner
