Lumbar facet (zygapophysial) arthropathy is a common cause of chronic lower back pain, and percutaneous radiofrequency denervation of the facet joints appears to be an effective treatment that yields long-term improvement. A technique utilising a distal approach to place the needle parallel to the medial branch has recently come into common use. In the present study, a technique incorporating a distal approach and an A-P fluoroscopic view was investigated.
