A comparison of the neuroablative effects of conventional and pulsed radiofrequency techniques.

Objectives: To compare the neuroablative effects of pulsed radiofrequency (PRF) and conventional radiofrequency (CRF) techniques on the sciatic nerve, a peripheral nerve that includes motor, sensory, and autonomous fibers.

Methods: The study consisted of 5 groups of 6 adult male Wistar rats. In the control group, no procedure was performed.

A comparison of conventional and pulsed radiofrequency denervation in the treatment of chronic facet joint pain.

Objectives: The goal of this study was to compare the effects of conventional radiofrequency (CRF) and pulsed RF (PRF) denervation to medial branches of dorsal rami in the treatment of facet joint pain.

Methods: The patients greater than 17-year old, with continuous low back pain with or without radiating pain with focal tenderness over the facet joints, pain on hyperextension, absence of neurologic defect, unresponsiveness to conservative treatment, no radicular syndrome, and no indication for low back surgery were included in the study. Local anesthetic was applied in the control group (n=20), whereas 80 degrees C CRF were applied in the CRF (n=20) and 2 Hz PRF were applied in the PRF group (n=20).
