Foraminal Stenosis

Although quite similar to spinal stenosis, foraminal stenosis is singled out because it primarily will affect one or more vertebral foramen.  When looking at a normal spine there is enough room for the nerve roots to slip through the foramen.  The foramen can become clogged with debris as we age trapping and compressing nerves

When the nerve root leaves the canal through the lateral foramen, a side hole in the canal, a bone spur that may have developed as a result of a degenerating disc may press on that nerve root.  This is the most common form of spinal stenosis and is termed lateral spinal stenosis.  When examining foraminal stenosis, the majority of the cases will occur at the lowest lumbar level of the back.  When the emerging nerve root in this area is trapped a major part of the sciatic nerve is compromised. Although not all stenosis cases are critical, if ignored, loss of function may occur if nerves die.  The ability to feel and move can be part of this function loss.
