MRI Findings of Disc Degeneration Are More Prevalent in Adults with Low Back Pain Than in Asymptomatic Controls: A Systematic Review and Meta-Analysis

DISC COMMENTARY
This companion study to a related review directly compares symptomatic and pain-free adults aged 50 and under, to identify which specific MRI imaging features of disc degeneration are actually more strongly linked to low back pain rather than simply present with age.
What was studied?
The meta-analysis combined 14 studies and over 3,000 participants, 1,904 with symptoms and 1,193 without, comparing specific imaging findings such as disc bulge, spondylolysis, disc extrusion, Modic type 1 changes, disc protrusion, canal narrowing and annular fissures.
What did they find?
Disc bulge, spondylolysis, disc extrusion, Modic type 1 changes, disc protrusion and general disc degeneration were genuinely more common in people with low back pain. Most other findings, including most Modic changes, canal narrowing, high-intensity zones, annular fissures and spondylolisthesis, showed no significant link to pain.
Why it matters
This helps distinguish which specific scan findings genuinely correlate with symptoms and which do not, since not every degenerative finding on a report carries the same clinical significance.
Why we included it
It reinforces a wider principle for interpreting imaging: treating every reported finding as equally significant misleads patients, whereas precision about which findings actually correlate with symptoms leads to more focused, useful conversations.
