Interventions for low back pain: what does the evidence tell us.

Although interventional therapy for chronic spinal pain continues to be popular among patients and providers, the scientific evidence supporting these techniques has lagged behind their presence in the market. This article collates both classic and more recent experimental results involved in the interventional assessment and treatment of chronic spinal pain, and presents key findings for physicians. Although much of the body of evidence is either unsupportive or inconclusive, there are some definitive findings involving each technique that can help shape rational practice. As interventional pain medicine seeks to become a more validated specialty, introspection and advancing science will be key to this development.
