Discography is considered for patients who, despite extensive treatments, have disabling lower back pain, groin pain, hip pain, and/or leg pain. When a variety of spinal diagnostic procedures have failed to elucidate the primary pain generator, these individuals may benefit from lumbar discography especially if spine surgery is contemplated. The lumbar discogram is designed to locate pain in a sensitive disc. A spinal fusion procedure that is designed to obliterate an internally disrupted, painful disc (pain generator) would not be the procedure of choice if pressurization of the disc didn’t reproduce the patient’s clinical discomfort. The spine surgeon needs to be absolutely sure that the level or levels being fused are responsible for the patient’s pain.
