This comprehensive overview addresses interventional pain techniques for managing lumbar spine-related pain, emphasizing the importance of exhausting conservative treatments such as physical therapy and non-opioid medications before considering more invasive options. Exceptions include cases involving severe neurological deficits, infections, or cancer, which may require immediate intervention. Various approaches to epidural steroid injections (ESIs) are discussed for both diagnosing and treating radicular pain. Treatments for axial back pain include facet joint injections, radiofrequency ablation, and myofascial trigger point injections, along with newer methods such as regenerative medicine and neuromodulation via peripheral or central pathways. The frontier of minimally invasive procedures, such as percutaneous image-guided lumbar decompression, interspinous process fixation, and sacroiliac joint fusion, is also explored. Emerging treatments for cancer-related spinal pain, including spinal cord stimulation, vertebral augmentation, intrathecal infusion, and tumor ablation, are presented as well. With the field evolving rapidly and taking on an increasingly surgical focus, the need for ongoing research to optimize safety and efficacy is emphasized, along with the importance of integrating these techniques into fellowship training.
