Its the most common form of spinal stenosis.

Spinal stenosis anatomy. The purpose of this article is to help you understand the basic anatomy associated with spinal stenosis a condition known to cause narrowing of the spinal canal andor nerve passageways that leads to nerve andor spinal cord compression. There are specific names for spinal stenosis depending on the exact locations of where the narrowing and nerve compression occurs. Spinal stenosis may also affect the cervical or thoracic region in which case it is known as cervical spinal stenosis or thoracic spinal stenosis.

Whatever the cause extra movement in the bones of the spine can lead to spinal stenosis and myelopathy. The two main types of spinal stenosis are. In this condition the narrowing occurs in the part of the spine in your neck.

In this condition the narrowing occurs in the part of the spine in your lower back. Spinal stenosis is a condition in which your spinal canal narrows. Anatomy of the spine each vertebra has a large opening at the rear called the spinal canal.

In the cervical and thoracic regions of the spine the spinal cord travels through this space. It may cause back pain and other nerve related problems. Spinal stenosis is a narrowing of the spinal canal that causes pressure on nerves traveling to the legs and arms.

Spinal stenosis usually affects the cervical neck and lumbar low back spinal regions. Spinal stenosis results from progressive narrowing of the central spinal canal and the lateral recesses. Spinal stenosis can occur when a disc in the neck herniates.

Normally the shock absorbing disc is able to handle the downward pressure of gravity and the strain from daily activities. The essential content of the spinal canal includes the spinal cord the cerebrospinal fluid csf of the thecal sac and the dural membranes that enclose the thecal sac. Occurrence in the thoracic uppermid back spine is rare.

Spinal stenosis occurs when the space around the spinal cord narrows. This puts pressure on the spinal cord and the spinal nerve roots and may cause pain numbness or weakness in the legs. In the lumbar region of the spine this opening contains a bundle of nerve roots.

Some people are born with the condition while others have wear and tear on the vertebrae spine bones. With proper exercise and treatment you can reduce its effects. This illustration shows a healthy vertebra cross section view and a vertebra with narrowing of the spinal canal called stenosis.

Spinal stenosis is a general term for the narrowing of one or more foramina bony openings within the spine.
