ObjectiveMetastatic bone pain is characteristic of cancer pain and is a form of refractory cancer pain, as the pain includes not only nociceptive but also neuropathic pain. Although some drugs are effective in the management of painful bone metastases, pain while moving is one of the most refractory forms of pain. Although pulsed radiofrequency (RF) dramatically reduces neuropathic pain, chronic pain, and vertebral metastatic pain, the number of cases reported in these studies was very small (five or less).DesignCase report.SettingSingle pain center.PatientsFifteen patients suffering from intractable vertebral metastatic pain.InterventionsDorsal root ganglion (DRG) pulsed RF.Outcome MeasuresA numerical rating scale (NRS) of pain at rest and while moving.ResultsAlmost all patients experienced sound pain relief after the pulsed RF treatment. There were no severe side effects reported.ConclusionDRG pulsed RF procedure provided sound pain relief for patients with intractable vertebral metastatic pain.
