A C2-3 zygapophygeal joint is a major source of cervicogenic headache. Radiofrequency (RF) neurotomy is preformed widely for zygapophygeal joint pain. Conventional RF denervation technique is generally performed under fluoroscopic control. Recently, ultrasound-guided radiofrequency on zygapophygeal joint has emerged as an alternative method. We report our experiences of two successful ultrasoun...

BACKGROUND Clinical studies have demonstrated the efficacy of pulsed radiofrequency (PRF). PRF energy is delivered to neural structures via specifically designed, percutaneously placed needles to treat some chronic pain states. PRF was introduced as a non-destructive alternative to destructive lesioning produced by continuous radiofrequency (CRF) energy. However, there is an ongoing controversy...

Pain Physician Vol. 9, No. 3, 2006 To the Editor: We consistently obtain similar clinical outcomes using pulsed radiofrequency (PRF) applications to those reported by Rozen and Parvez (1). In agreement, our clinic has been successfully treating post inguinal herniorrhaphy pain for 10 years using PRF applications to the dorsal root ganglia. Thus, we thank the authors for their report. We do note...
