Abstract
Lumbar zygapophyseal joints are important causes of low back pain without neurological deficits. Pathogenesis of lumbar zygapophyseal joints pain are various due to the anatomical and biological characteristics. Their clinical features have many common symptoms but not definitive symptoms. Facet block or medial branch block of dorsal ramus are useful in the diagnosis. Treatment is mainly conservative care including medication and facet block. In some cases, percutaneous electrocauterization of lumbar medial branch is an effective means of long-term treatment.
