The method includes positioning a hollow shaft through the cortical shell of a vertebral body and into a cancellous bone region of the vertebral body. The hollow shaft includes an annular wall having a longitudinal bore therein, a proximal portion and a distal portion, and a first window extending transversely through the annular wall. An electrosurgical probe is advanced within the longitudinal bore from the proximal portion toward the distal portion. The electrosurgical probe includes a first treatment element at a distal end of the probe, wherein the first treatment element being in electrical connection with a power supply. The first treatment element is slidably disposed within the longitudinal bore so that the first treatment element is advanced radially outward from the window and shaft to affect treatment of the intraosseous nerve within the cancellous bone region.
