Lumbar Medial Branch Radiofrequency Neurotomy: How Understanding Anatomy, Patient Selection, and Technique Affect Outcomes (410)

11 am–Noon Sunday, March 10

A successful outcome of lumbar medial branch radiofrequency neurotomy (LMBRFN) is dependent on careful attention to principles of facet join pain diagnosis and elements LMBRFN procedure technique. This session will present in depth discussion of these multiple, intricate factors. The relevant anatomy, diagnostic standards, and physics of radiofrequency lesions as applied to LMBRFN will be detailed, as supported by the current medical literature.

Learning Objectives:

  • Recognize the exact anatomy of the lumbar medial branch nerves and how they can be best accessed.
  • Define the diagnostic principles of medial branch nerve blocks and how they can be interpreted to define a 'positive' for patient selection, based on the best medical evidence.
  • Summarize the physics the lesioning the medial branch nerves via radiofrequency technology, in a manner that is most likely to achieve effective coagulation of the nerve, based on the medical literature.
