Foraminal Stenosis

What is Foraminal Stenosis?

Foraminal stenosis, or narrowing, occurs when the open canals between the spinal vertebrae (intervertebral foramina) are compressed by bone or soft tissue, often due to degenerative changes in the spinal anatomy. Spinal nerve roots must travel through these hollow archways as they branch out from the spinal cord to reach other areas of the body.

Stenosis can be caused by other spinal injuries such as a herniated disc, arthritis, bone spurs or from tumors developing near your spinal cord. Most often though, like other spine ailments, it is caused by normal wear and tear of a certain region of your spine that gets the most use. Commonly related to the areas affected by Osteoarthritis.
