Degenerative Changes on MRI: What They Mean, Common Sites & Management

"Degenerative changes" on MRI = age/wear-related structural alterations. Often asymptomatic; correlate poorly with pain.

Common Manifestations by Region

• Spine: Disc desiccation (T2 signal loss), height loss, bulge/herniation, annular fissure, Modic changes (endplate), facet arthropathy, ligamentum flavum hypertrophy, spinal/foraminal stenosis.
• Joints (Knee, Hip, Shoulder): Cartilage thinning/fibrillation, osteophytes, subchondral sclerosis/cysts, meniscal/labral fraying, effusion.
• Brain: Cortical atrophy, ventricular enlargement, white matter hyperintensities (WMH), microbleeds.
• Muscle/Tendon: Fatty infiltration, atrophy, tendinosis, partial tears.

Etiology

Mechanical loading, genetics, metabolic (diabetes), inflammation, prior injury, sedentary lifestyle.

Clinical Correlation Is Key

• Incidental findings ubiquitous: >50% of asymptomatic 40yo have disc bulges.
• Treat the patient, not the image. Match symptoms to level/pathology.

Management

1. Conservative: PT (core, mobility), NSAIDs, activity modification, weight loss, injections (ESI, HA, PRP).
2. Surgical: Decompression (stenosis), fusion (instability), arthroplasty (end-stage OA), discectomy (radiculopathy failing conservative).
3. Lifestyle: Anti-inflammatory diet, sleep, smoking cessation, graded exercise.

Radiologist's report describes morphology; clinician determines relevance.
