Bipolar Intra-articular Radiofrequency Thermocoagulation of the Thoracic Facet Joints: A Case Series of a New Technique.
BACKGROUND
This study tests the hypothesis that of bipolar radiofrequency thermocoagulation of the thoracic facet joint capsule may provide a safe and effect method of pain control from thoracic facet origin.


METHODS
Among patients suffering from localized mid back pain, nine patients with thoracic facet disease confirmed by magnetic resonance image and diagnostic thoracic facet block were enrolled. Bipolar radiofrequency ablation in the inferior aspect of the thoracic facet joint was done. Visual Analog Scale (VAS) was measured pre-intervention and 1 month post-intervention. Any complications and changes in amount of pain medication were recorded.


RESULTS
Significant 47.6% reduction in VAS was noted at 1 month. There were no serious complications.


CONCLUSIONS
Intra-articular bipolarradiofrequency thermocoagulation of the thoracic facet joint may be a technically easier and valid method of treating mid back pain of thoracic facet origin.
