ABSTRACT
Discography was first named by Lindblom 1 when he described diagnostic disc puncture. Hirsch 2 used the procedure to identify painful discs in patients with sciatica and lumbar pain. The foundation of the practice of discography was thus begun, and Lindblom did further work using the injection of contrast media to visualize radial tears in the annulus, thus expanding the diagnostic information from intervertebral discs. Pain provocation upon injection served to localize the painful disc, and radiographic appearance with contrast gave information about the internal morphology of the disc.
