Flashcards
Central Lumbar Stenosis
Central Lumbar Stenosis
A condition where the spinal canal in the lower back (lumbar region) narrows, putting pressure on the spinal cord.
Ligament Overgrowth in Central Lumbar Stenosis
Ligament Overgrowth in Central Lumbar Stenosis
The ligaments in the back can thicken and harden, putting pressure on the spinal cord.
Facet Joint Overgrowth in Central Lumbar Stenosis
Facet Joint Overgrowth in Central Lumbar Stenosis
The facet joints, located in the back of the spine, can develop bony growths, also putting pressure on the spinal cord.

Study Notes
Central Lumbar Stenosis
- Narrowing of the lumbar spinal column.
- Compression of the spinal cord.
- Ligaments originating from the back contribute to the compression.
- Compression also occurs from lateral aspects.
- Overgrowth on facet joints and calcification of ligaments contribute to the spinal narrowing.
- Condition is often bilateral (affects both sides).
- All sensory (dermatomes) and motor (myotomes) functions below the affected level are likely affected.
Causes of Spinal Compression
- Abnormal spinal movement (spondylolisthesis). Spondylolisthesis can be either anterior (ante) or posterior (retro).
- Compression at specific vertebral levels (e.g., C3-4, C4-5, though the context refers to lumbar stenosis)
- Thickening of the ligamentum flavum (posterior spinal canal compromise).
