For anatomical understanding of the spinal canal
In order to make the clinical picture understandable, the anatomical structure will be discussed first. The spinal column, the stable mast of the back, forms a canal in its center of bony protection. The spinal cord, which originates from the brain and consists of long nerve fibers and cell bodies, runs through this channel.The brain and the spinal cord form the important central nervous system, which is responsible, among other things, for the execution of movements, body control and the processing of information coming from the body and the environment.
In the area of the small holes between the individual vertebral bodies, the spinal nerves emerge from the spinal cord, which finally move as so-called peripheral nerves into the different regions of the body, or from the body regions back to the central nervous system. The intervertebral discs are located between the individual vertebral bodies, which ensure flexibility and cushion and evenly distribute loads. Various ligaments surround the individual vertebrae and the entire spinal column from the skull to the pelvis as a passive support system.
The trunk muscles, which surround the spine on all sides and support it like a mast on a sailing boat, act as active stabilization. This includes the back muscles as well as the abdominal muscles. The muscles and the complex flexible structure of the spine enable it to move forward, backward, sideways and rotate. When bending forward, the nerves of the spinal cord are stretched, the spinal canal becomes wide and space is created in the back. In contrast, stretching backwards causes a narrowing of the spinal canal.
Summary
Spinal canal stenosis of the lumbar spine describes a narrowing of the canal leading to the spinal cord in the area of the lower back with unpleasant symptoms such as radiating pain, sensitivity disorders and severe weak legs. The symptoms can usually be reduced by physiotherapy, relieving exercises and lots of movement. Self-exercises for strengthening and mobilization should be integrated into everyday life.
