Lindblom ﬁrst described discography as a useful tool to identify intervertebral disc ruptures in 1948. The management of chronic low back pain presents a challenge to the spine specialist. With improved understanding of it's pathophysiology, a discogenic etiology is widely accepted and exists in a considerable number of patients with chronic back disorders. The disc has nociceptive innervation capable of pain generation.
An annular tear is the most common cause of chronic low back pain and it may be that annular injuries that do not adequately heal, evolve into painful degenerated discs. Surely chronic discogenic pain results from mechanical stimulation of annular ﬁssures and chemical irritation (neuropathic pain) from inﬂammagenic disc break-down substances.
