Interventional approach to low back pain.

Chronic low back pain (LBP) places a tremendous economic burden on society due to both direct and indirect costs. Health care costs for adults with chronic LBP have steadily increased over the past 20 years, coinciding with a large increase in the utilization of spinal injections, surgical interventions, opioid medications, and physical therapy. The treatment of LBP is best approached by a multimodal and even multidisciplinary approach with a combination of physical rehabilitation, pharmacologic management, psychological intervention, spinal injections, and surgical intervention with a goal of improving the functional status of the patient. In this review, we discuss the interventional management of LBP secondary to herniated nucleus pulposus, spinal stenosis, facet mediated pain, sacroiliitis, and discogenic pain.
