Abstract
Described herein are various implementations of systems and methods for treating back pain (e.g., chronic low back pain) caused by different (e.g., independent) sources of pain, such as pain originating or stemming from intervertebral discs, from vertebral endplates, and/or from intraosseous locations within one or more vertebral bodies. For example, methods for treating back pain (e.g., chronic low back pain) may involve both vertebral fusion (e.g., arthrodesis or spondylodesis to fuse adjacent vertebrae) and neuromodulation (for example, ablation of nerves within or surrounding one or more of the adjacent vertebrae). The neuromodulation may facilitate treatment of pain that is generated by insertion of fusion hardware.
Claims25
A method of treating multiple independent sources of low back pain of a patient during a single therapeutic intervention, the method comprising:
- performing a spinal fusion procedure between two adjacent vertebrae of the patient, wherein the spinal fusion procedure comprises leaving one or more hardware components within or surrounding each of the adjacent vertebrae;
- inserting an access tool within an inner cancellous bone region of a vertebral body of one of the two adjacent vertebrae while avoiding contact with the one or more hardware components, the access tool comprising a lumen extending therethrough to facilitate access to the inner cancellous bone region;
- inserting a nerve ablation device through the lumen of the access tool until at least a distal end of the nerve ablation device extends beyond the access tool within the inner cancellous bone region,
- wherein the nerve ablation device comprises a bipolar radiofrequency probe;
- ablating a basivertebral nerve within the inner cancellous bone region using the bipolar radiofrequency probe;
- and
- removing the bipolar radiofrequency probe and the access tool from the patient.

- modulating a basivertebral nerve within the inner cancellous bone region using the neuromodulation device;
- and
- removing the neuromodulation device and the access tool from the patient.
