A radiofrequency denervation is a procedure where a needle sized probe is used to create a heat lesion with a goal of interrupting the pain signals stemming from the facet joints of the spine. The spine is made up of bones called vertebrae. Between each vertebrae is a hinge-like joint called a facet joint. The facet joints lengthy vertebrae together. The joints are innervated by nerve skull medial branch nerves. When a facet joint becomes arthritic, patients experience neck or back pain. The procedure is performed under light sedation and typically takes 15-20 minutes. The effectiveness can last for 6-18 months. Sometimes, when the nerves regrow, the pain does not return. If it does, the procedure can be repeated.
