Summary: | Facet joint arthrosis is a progressive degenerative disease that is frequently associated with other spinal
degenerative disorders such as degenerative disc disease or spinal stenosis. Lumbar facet joint arthrosis
can induce pain in the proximal lower extremities. However, symptoms and imaging findings
of “facet joint syndrome” are not specific as they mimic the pain from herniated discs or nerve root
compression. Currently, evidence for therapeutic intra-articular lumbar facet joint injections is still
considered low, with a weak recommendation strength. Nevertheless, some studies have reported
therapeutic effectiveness of facet joint injections. Moreover, the use of therapeutic facet joint injections
in clinical practice has increased. This review article includes opinions based on the authors’ experience
with facet joint injections. This review primarily aimed to investigate the efficacy of lumbar
facet joint injections and consider their associated safety aspects.
