Disc height discrepancy between supine and standing positions as a screening metric for discogenic back pain in patients with disc degeneration.

Abstract

The diagnosis of discogenic low back pain (LBP) from disc degeneration of the lumbar spine is often evaluated with discography. Noninvasive, simple screening methods other than invasive discography are useful, as evidence supporting clinical findings and magnetic resonance imaging (MRI) have come to the forefront.
