Spinal stenosis can be defined as a general term that is used to describe the narrowing of certain passageways or canals in which nerves pass through in our spine. For instance, one example can be narrowing of the lateral recess canal, which is something I specifically have myself. Now, the narrowing of these canals can be a result of multiple factors such as a disc protrusion, hypertrophy of the facet joints, ligament flavum hypertrophy, etc. All of these examples mentioned could cause some narrowing and possibly put pressure on a traveling nerve root. This is where the term spinal stenosis comes in, and it’s mainly just a term to describe the narrowing of some of these passageways or canals.
