End-on Versus Parallel Radiofrequency Lesioning for Neurotomy of the Cervical Medial Branch Nerves
Sponsor: University Health Network, Toronto
Summary
Aim of the EndPaRL study is to compare the efficacy and effectiveness of the two techniques utilizing sharp straight conventional radiofrequency needle with a trident needle for radiofrequency neurotomy of Cervical Medial Branch Nerves (CMBNs), in patients presenting with chronic, moderate-to-severe, neck pain due to cervical zygapophyseal joint osteoarthritis, as diagnosed by positive responses to two consecutive diagnostic blocks with local anesthetic of the CMBN.
