This 2008 systematic review synthesizes the literature on Modic changes (MC) — MRI-visible bone marrow and endplate signal abnormalities classified by Modic et al. in 1988 — covering their classification, prevalence, natural history, proposed mechanisms, relationship to low back pain, and implications for clinical management and differential diagnosis.
When you see Type I MC adjacent to a degenerated disc in a patient with axial LBP, recognize it as the most inflammatory and symptomatically active subtype — it predicts hypermobility, correlates with discographic pain reproduction, and may predict better response to intradiscal steroids while signaling higher risk of poor outcomes after discectomy or recurrence after endoscopic procedures.
Differentiating MC from spondylodiscitis on MRI hinges on disc signal (preserved/hypointense in MC vs. Hyperintense in infection), erosion pattern (linear/parallel to endplate in MC vs. Irregular erosion in infection), and the absence of paravertebral soft-tissue edema or epidural mass in MC.
