Summary
This study shows a new device can be accurately placed in the spine to ablate the basivertebral nerve (BVN), offering a promising treatment for vertebrogenic back pain.
Area of Science:
- Spine surgery
- Pain management
- Biomedical engineering
Background:
- Minimally invasive basivertebral nerve (BVN) ablation effectively treats vertebrogenic back pain.
- Developing new devices is crucial for refining BVN ablation procedures.
Purpose of the Study:
- To simulate the placement of a novel multitined expandable electrode for BVN ablation.
- To assess the feasibility of achieving correct device tip positioning for lesion formation.
Main Methods:
- CT scan reconstructions of 31 lumbosacral spines (L1-S1) were used.
- Simulated intravertebral placement of a novel multitined expandable electrode in bipolar configuration.
- Successful deployment required tip distances between 10 mm and 20 mm.
Main Results:
- Mean tip distances ranged from 11.35 mm (L5) to 11.87 mm (L3), with no significant differences across vertebral levels.
- 90% of simulated placements achieved acceptable tip distances (10-20 mm).
- Significant association found between vertebral level and device angulation.
Conclusions:
- The multitined electrode is feasible for intraosseous placement in the vertebral body.
- This validates the device's potential for effectively ablating the BVN plexus.
- Provides evidence for a new minimally invasive treatment for back pain.
