1. A method of treating back pain of a subject, the method comprising:
- performing a spinal fusion procedure between two adjacent vertebral bodies;
inserting a distal end of a first pedicle screw within a cancellous bone region of a first vertebral body of the two adjacent vertebral bodies, wherein the first pedicle screw comprises a channel extending along a length of the first pedicle screw;
inserting a first radiofrequency energy delivery device through the channel of the first pedicle screw;
inserting a distal end of a second pedicle screw within the cancellous bone region of the first vertebral body, wherein the second pedicle screw comprises a channel extending along a length of the second pedicle screw;
inserting a second radiofrequency energy delivery device through the channel of the second pedicle screw;
applying radiofrequency energy using the first and second radiofrequency energy delivery devices to conduct heat to the cancellous bone region of the first vertebral body sufficient to ablate a nerve within the cancellous bone region of the first vertebral body.

Abstract
Methods of using hardware (e.g., bone screws, anchors or other devices) previously inserted within the body to facilitate energy delivery are disclosed. The energy delivery (e.g., thermal energy) may be used for neuromodulation (such as stimulation or denervation), tissue heating and ablation, curing, and other applications in the spine and non-spine orthopedic locations.
