Lumbar Spinal Stenosis
Lumbar spinal stenosis is a common cause of low back and leg pain, or sciatica.
As we age, the normal wear-and-tear effects of aging can lead to narrowing of the spinal canal, which houses the spinal nerves and spinal cord. This condition is called spinal stenosis.
Degenerative changes of the spine are seen in up to 95% of people by the age of 50. Spinal stenosis most often occurs in adults over 60. Pressure on the nerve roots is equally common in men and women.
A small number of people are born with back problems that develop into lumbar spinal stenosis. This is known as congenital spinal stenosis. Typically, this occurs in people who are born with a smaller spinal canal; because there is less space within the canal, degeneration, or arthritis, can affect them sooner. Congenital spinal stenosis occurs most often in men. People usually first notice symptoms between the ages of 30 and 50.
