Lumbar Spinal Stenosis
了解 Lumbar Spine Magnetic Resonance Imaging 影像中的 Lumbar Spinal Stenosis，明确其含义与下一步措施。
影像表现
Magnetic Resonance Imaging FindingNarrowed central canal with crowding of cauda equina; hypertrophic ligamentum flavum and facet arthropathy common.
临床意义
Causes neurogenic claudication; imaging guides surgical decompression planning.
What is Lumbar Stenosis?
Canal narrowing compressing nerve roots, usually degenerative. MRI shows the level and cause of compression.
Imaging Appearance
- Reduced AP canal diameter
- Facet overgrowth, ligamentum flavum thickening
- Disc bulge or herniation contributing
- CSF effacement with nerve root crowding
Clinical Significance
- Correlates with neurogenic claudication and radicular pain
- Guides level(s) for decompression
Symptoms
- Leg pain/weakness worsened by walking, relieved by sitting/flexion
Diagnosis
- MRI lumbar spine
- Physical exam: shopping-cart sign
Treatment
- Physical therapy, NSAIDs, epidural steroids
- Surgical decompression ± fusion for refractory cases
Prognosis
- Many improve after decompression; PT can help mild cases
What Should You Do?
- Trial flexion-based PT and posture modifications.
- Discuss surgery if walking limited despite therapy.
- Monitor new weakness or bladder changes urgently.
