Randomized controlled trials between dorsal root ganglion thermal radiofrequency, pulsed radiofrequency and steroids for the management of intractable metastatic back pain in thoracic vertebral body.

Background: Bone metastasis is a complication of various cancers causing severe pain. The current modalities for the treatment of metastatic axial pain include pharmacological, surgical and vertebral augmentation techniques, each of which has its own challenges.

Objectives: To evaluate the effectiveness of pulsed radiofrequency (PRF), thermal radiofrequency (RF) and steroids on dorsal root ganglion (DRG) in patients with thoracic axial pain due to vertebral metastasis.
