Implication

Prospective cross-sectional study demonstrates distinct origins of disc and zygapophyseal joint pain in chronic low back pain, suggesting dual pathology is uncommon.

Key Points

To evaluate the relative contributions of the intervertebral disc and the zygapophyseal joint as independent or concurrent pain generators in patients with chronic low back pain.
Prospective cross-sectional analytic study conducted in 92 consecutive patients presenting with chronic low back pain.
All patients underwent both diagnostic discography and dual diagnostic blocks of the zygapophyseal joints utilizing lignocaine for screening and bupivacaine for confirmation.
Thirty-six patients (39%) had at least one positive discogram based on exact pain reproduction, an abnormal morphological image, and a negative control.
Eight patients responded positively to both the initial lignocaine screening block and the confirmatory bupivacaine zygapophyseal joint block.
Only 3 patients demonstrated both a positive discogram and symptomatic zygapophyseal joint pain simultaneously.
