What is ligamentous hypertrophy?


Answers:    Hypertrophy of the ligaments in the vertebral canal of the spinal column can increase their mass enough that they come to a point the canal (stenosis) sometimes to the point that the spinal cord and/or nerve roots running through the canal are compressed. When the posterior longitudinal ligament contained by front and ligamentum flavum behind the spinal cord hypertrophy the cord is almost "circumferentially" surrounded and compressed.
rtrophy of the ligamentum flavum laterally near the facet joint can also contribute to foraminal narrowing (stenosis) next to potential nerve compression (pinching). Source(s): http://uscneurosurgery.com/glossary/h/hy…
