Facet joint injections deliver anti-inflammatory medication directly to inflamed spinal joints under image guidance. Medial branch blocks target the small nerve branches carrying pain signals from facet joints. They provide temporary relief and help confirm the pain source. Radiofrequency ablation uses heat to interrupt nerve signals responsible for chronic facet pain, with relief typically lasting six months to two years. Epidural steroid injections reduce inflammation around compressed nerve roots and are commonly used for herniated discs, spinal stenosis, and radiating arm or leg pain.
