Cervical Spinal Stenosis
A Patient's Guide to Cervical Spinal Stenosis
What parts make up the spine and neck ?
The spine is made of a column of bones. Each bone, or vertebra, is formed by a round block of bone, called a vertebral body. A bony ring attaches to the back of the vertebral body, forming a canal.
This bony ring is formed by two sets of bones. One set, the pedicle bones, attaches to the back of each vertebral body. On the other end, each pedicle bone connects with a lamina bone. The lamina bones form a protective roof over the back of the spinal cord. When the vertebra bones are stacked on top of each other, the bony rings forms a long bony tube that surrounds and protects the spinal cord as it passes through the spine.
An intervertebral disc fits between each vertebral body and provides a space between the spine bones. The disc works like a shock absorber. It protects the spine against the daily pull of gravity. It also protects the spine during activities that put strong force on the spine, such as jumping, running, and lifting.
An intervertebral disc is made up of two parts. The center, called the nucleus, is spongy. It provides most of the ability to absorb shock. The nucleus is held in place by the annulus, a series of strong ligament rings surrounding it. Ligaments are strong connective tissues that attach bones to other bones.

Why do I have this problem?
The bony spinal canal normally has more than enough room for the spinal cord. Typically, the canal is 17 to 18 millimeters around, slightly less than the size of a penny. Spinal stenosis occurs when the canal narrows to 13 millimeters or less. When the size drops to 10 millimeters, severe symptoms of myelopathy occur. Myelopathy is a term for any condition that affects the spinal cord. The symptoms of myelopathy result from pressure against the spinal cord and reduced blood supply in the spinal cord as a result of the pressure.
Spinal stenosis may develop for any number of reasons. Some of the more common causes of spinal stenosis include
Some people are born with a spinal canal that is narrower than normal. This is called congenital stenosis. They may not feel problems early in life, but having a narrow canal to begin with places them at risk for stenosis. Even a minor neck injury can set them up to have pressure against the spinal cord. People born with a narrow spinal canal often have problems later in life, because the canal tends to become narrower due to the affects of aging. These degenerative changes often involve the formation of bone spurs (small bony projections) that point into the spinal canal and put pressure on the spinal cord.
