About Spinal Stenosis
Narrowing or stenosis of the spine occurs most commonly in the cervical and lumbar spine. This most commonly develops slowly over months and years. It can contribute to compression or pinching upon the spinal cord or nerves. Pinching on the spinal cord causes myelopathy which produces unsteadiness of gait and can progress to being wheelchair bound or paralysis. Narrowing of the foramen or lateral recess of the spine typically pinches nerve(s) which create pain most commonly known as sciatica or radiculopathy. This can be self limiting or even require surgery if not resolved. Narrowing of the central canal in the lumbar spine can cause neurogenic claudication which is improved by leaning forward while walking, for example leaning forward on a grocery cart.
