 Facet joint pain is a common cause of chronic low back pain, but it is difficult to diagnose and treat. Intraarticular injections, medial branch blocks, and radio frequency neurotomy are all options for treating this type of pain, but there is limited evidence regarding their effectiveness. Spinal anatomy is essential for performing these procedures safely and effectively, so it is important for pain physicians to understand the relevant anatomy. We reviewed the anatomy of the lumbar spine and its relevance to interventional pain management related to facet joint injections. Additionally, we provided a comprehensive review of the procedure and clinical evidence. This article was authored by Hyung Sun Won, Myung Young, and Young Dong Kim.
