Spinal Stenosis. What is Spinal Stenosis? Spinal stenosis is defined as the narrowing of the spinal canal, most often in the cervical (neck) area and in the lower back (lumbar) region. This condition places pressure on the spinal cord, with patients most often experiencing problems when inflammation of the nerves occur as the pressure is increased.
Terminology for CT scans and MRI scans (Lumbar region) Spinal stenosis â This means that the spinal canal is narrowed. This is usually because the joints that are between the vertebrae, called the facet joints, have hypertrophied (become larger) secondarily to osteoarthrosis of these joints. At the same time the ligament that runs inside the spinal canal, the ligamentum flavum, has also hypertrophied and is pushing on the nerves.
