is foraminal stenosis
Foraminal Stenosis. Foraminal stenosis is a narrowing of the spinal foramen, the hole through which passes a spinal nerve as it exits the spine (foramen basically just means hole). It is usually a form of degenerative spine disease which occurs slowly over time with wear and tear of the spinal column.t each level, a spinal nerve, a nerve coming to or from the spinal cord, passes through the foramen. Because the foramen is a relatively small area, anything impinging on that area can cause foraminal stenosis is pinch the nerves inside the foramen.
