In this study we will prospectively examine the safety and clinical effects of ultrasound-guided cervical medial branch blocks.


While several clinical trials have found that ultrasound guidance provides similar accuracy to fluoroscopy and reduces performance times for cervical medial branch blocks, larger studies documenting safety-related outcomes are lacking. In addition, although cervical medial branch blocks are an accepted tool to diagnose neck pain originating from the cervical facets, there are reports of long-lasting analgesic effects in a subset of patients, suggesting that these blocks may have long-term benefits. We therefore propose to prospectively examine the incidence of adverse events, as well as the clinical long-term effects of ultrasound-guided cervical medial branch blocks, in a cohort of pain clinic patients undergoing these procedures as part of their usual care.
