    Abstract:
    BACKGROUND: The aim of this study is to assess the efficacy of pulsed RF lesioning of cervical medial branches in patients with whiplash-related chronic cervical zygapophysial joint pain in whom other conservative treatments failed. METHODS: Cervical zygapophysial joint pain was confirmed in 14 patients undergoing double diagnostic blocks. These patients underwent pulsed RF lesioning of the cervical medial branches. Pulsed RF procedures were performed in 2 cycles of 180 seconds after localization under fluoroscopy guide. RESULTS: Twelve (85.7%) patients had substantial pain relief at 1 month. Eleven (78.3%) patients still had more than 60% pain relief at 6 months. Only 5 (35.7%) patients recurred within 12 months. At 12-month follow-up, 9 (64.3%) patients had significant pain improvement. Medication requirements decreased in 13 (92.8%) patients at 1 month, 12 (85.7%) patients at 6 months, and 10 (71.4%) patients at 12 months. CONCLUSIONS: Pulsed RF of cervical medial branches is a potential treatment for patients with chronic whiplash-related cervical zygapophysial joint pain that failed other conservative treatments. This treatment provides long-lasting pain relief and reduces pain medication requirements.
