Conclusion
HZ‐related pain, pain
The needle tip position had an influence on the PRF treatment in patients with HZ‐related pain. Positioning the needle tip in the area between the medial and lateral edges of adjacent pedicles offered good pain relief and improved quality of life in HZ patients.According to the dorsal root ganglion (DRG) position and needle tip position, patients were randomly allocated to the IP group (group inside of the pedicle) and OP group (group outside of the pedicle). This is the first study on two distinct needle tip positions in PRF for HZ‐related pain. In this study, it was shown that the patients in the IP group had significantly better pain relief and higher activities of daily living than that in the OP group.
