M99.31: Osseous stenosis of neural canal Cervical region

Changes to your vertebrae have caused a constriction in your vertebral canal in the cervical spine area.

The spine consists of several sections. The cervical spine begins below the head. The cervical spine is very mobile. Below that is the thoracic spine. The ribs are attached to the thoracic spine. Below the thoracic spine is the lumbar spine. The lumbar spine is also very mobile and it bears a large part of the body’s weight. After the lumbar spine, the sacrum and coccyx join. The vertebrae form the vertebral canal on the rear of the spinal column. The spinal cord runs in the vertebral canal. Nerve fibers run from the brain into the body via the spinal cord and form nerves there. Every nerve is responsible for a particular part of the skin and for certain muscles. These nerves are important for instance in enabling you to feel and move the muscles.

Changes to the vertebrae can have different causes. Wear and tear can cause the formation of bony outgrowths which constrict the vertebral canal. Injuries or surgery can also cause changes in the vertebrae which constrict the vertebral canal. When the vertebral canal is narrowed, the spinal cord can be damaged.

The narrowing of the spinal canal can cause pain or sensitivity disorders. This can affect your arms or chest, for example. For example, the skin in the affected areas may tingle or be numb. It may also be that you are no longer able to move certain muscles properly.
