Effect of pulsed radiofrequency in treatment of facet-joint origin back pain in patients with degenerative spondylolisthesis.

Background Degenerative spondylolisthesis is a well-recognized source of low back pain mainly induced by facet joint pain. Pulsed radiofrequency (PRF) allows heat dissipation, thus producing a temporary injury that affects only type C fibers responsible for pain conduction.
