ABSTRACT

Lumbar pain is a common and frequent chronic condition. It is estimated that facet joint pain represents 15-31% of all consultations for low back pain. In suspected facet joint pain, it is recommended to perform nerve blocks to establish the diagnosis. Percutaneous continuous radiofrequency is the most effective treatment to date. We describe the current evidence on the minimally invasive treatment of lumbar facet syndrome and our experience with image guidance with CT and fluoroscopy by means of rhizolysis of the medial branch of the dorsal primary ramus of the spinal nerve.
