AbstractLow back pain (LBP) is a major physical and socioeconomic entity. A significant percentage of LBP is attributable to internal disc disruption. The management of internal disc disruption has traditionally been limited to either conservative treatment or spinal fusion. Intradiscal electrothermal coagulation (IDET) and percutaneous neuromodulation therapy (PNT) are now being performed as an alternative to these therapies. Scientific data regarding the pathophysiology, biologic effects, and clinical results are relatively scarce. Early biomechanical and histologic investigations into the effects of IDET are conflicting. However, in early prospective human trials, IDET seems to provide some benefit with little risk. PNT represents a new less invasive technique for the treatment of discogenic pain, but limited research is available to determine long-term clinical efficacy. IDET and PNT are potentially beneficial treatments for internal disc disruption in carefully selected patients as an alternative to spinal fusion. More basic science and clinical research with long-term follow-up evaluation is necessary.
