MIAMI—For the treatment of spine pain, a novel, multi-tined radiofrequency (RF) expandable electrode produced a significantly larger thermal lesion surface area at the muscle–bone interface than a standard RF cannula, according to a study of an ex vivo model.
The study poster (abstract 15) from the 2022 annual meeting of the American Society of Pain & Neuroscience (ASPN) found that the mean area of lesion size for the multi-tined Nimbus cannula (Stratus Medical) with
