Abstract: BACKGROUND: Percutaneous radiofrequency (RF) rhizotomy of the medial branches of the dorsal rami from the spinal nerves is the standard treatment for cervical zygapophyseal joint mediated pain. There is a paucity of data regarding the longevity of analgesia following this procedure. OBJECTIVE: To determine the duration of complete pain relief, analgesic consumption and any adverse events following percutaneous cervical RF rhizotomy. METHODS: Retrospective chart review of patients who had undergone percutaneous cervical RF rhizotomy for zygapophyseal joint mediated neck pain. Patient reviews were undertaken by the pain consultant at 6 weeks, 6 months and 1 year following the procedure. Where follow-up was incomplete, the patient was assumed only to have had pain relief until their last review where complete pain relief had been documented. Analgesic consumption and any adverse events were recorded. The data was analysed using Microsoft Excel®. RESULTS: At 12 months 63.64% of patients were pain free. Median duration of complete pain relief was 52 weeks. Patients who experienced pain relief had ceased using prescription analgesia by their 6 week review. There were no repeat cervical RF rhizotomies, procedure related infections or unplanned hospital admissions. CONCLUSION: Percutaneous cervical RF rhizotomy is an effective treatment for cervical zygapophyseal joint mediated neck pain.
