Bilateral Foraminal Stenosis Definition
Bilateral foraminal stenosis details when the spinal nerve root is compressed on both sides due to narrowing of the foramen that may be caused by an enlarged joint, a collapsed disc space or a foraminal herniated disc. While compression on one side as opposed to both sides is more common, bilateral foraminal stenosis may occur in the cervical spine (neck) or the lumbar spine (lower back).
