To assess how macroscopic lumbar disc degeneration correlates with age, sex, and anatomical spinal level across pooled postmortem samples.
Synthesized data from 16 published studies evaluating macroscopic disc degeneration grades across 600 lumbar intervertebral discs from 273 cadavers aged 0 to 96 years.
Correlated degeneration severity scores against chronological age, biological sex, and specific lumbar vertebral levels.
Male discs showed greater macroscopic degeneration than female discs across most ages, reaching statistical significance during the second, fifth, sixth, and seventh decades.
Degenerative changes were most severe at the L3–L4 and L4–L5 levels compared to other lumbar spinal segments.

Implication

Pooled cadaver study reveals earlier lumbar disc degeneration in males and mid-lumbar levels, suggesting mechanical stress and limited nutrition drive tissue breakdown.
