Bipolar Lumbar Radiofrequency Medial Branch Neurotomy in a Patient with Deep Brain Stimulation Implant

Abstract

Chronic axial lower back pain is one of the most common conditions that patients seek medical attention for in pain practices. About 15 to 40% of axial lower back pain is due to facet-mediated pain. Diagnostic blocks of the medial branch reliably identify the facet joint as the pain generator and offer a prognostic factor for response to radiofrequency neurotomy of the identified facet joints resulting in profound pain relief. However, deep brain stimulation implants have been considered a contraindication for neurotomy. We present an illustrative case of a patient with deep brain stimulation system treated with bipolar medial branch neurotomy using a two-needle technique.
