Discogenic pain syndromes are incompletely understood but are increasingly believed to be causative of a large number of cases of chronic low back pain. Treatment choices for patients in whom conservative measures fail are limited, and surgical options have considerable cost, morbidity, and only variable effectiveness in pain relief. IDET is a minimally invasive treatment proposed as an alternative to surgery in patients with chronic discogenic low back pain syndromes. Although objective evidence of effectiveness is still being collected, this newly developed procedure is an excellent starting point in the development of minimally invasive techniques in treating discogenic pain and adds another valuable tool to the armamentarium of the practicing spine interventionist.
