Intervertebral injuries
The particular vertebrae of the backbone form a protective shield for the respectful spinal nerves. These nerves, depending on the backbone section, are responsible for the proper functioning of the subordinated body organs.
The above picture shows, that both the lower as well as upper surface of the vertebra are not completely flat, but slightly hollow, therefore it looks like a “ little bowl” The intervertebral disc is located between two such “ little bowls”, which makes it impossible for the disc to move forward, backward or sideways. The longitudinal ligaments, interior and posterior, form additional protection against the prolapse of disc, especially when a person leans forward or backward. In this type of movements a strong, one-way pressure is exerted on the disc, which without the additional protection might have been pushed out.

The substantial amount of water influences the elasticity of the intervertebral disc – as well as the articular cartilage. When the backbone becomes squeezed, the disc is deformed in such a way that – using an exaggeration “is going out sideways” The gelatinous nucleus inside becomes flattened and swelled on both sides, thus giving the possibility to pick up and cushion the blows and pressure. The healthy disc may be compared to the water cushion pool. In the opinion of doctor Biedermann, the intervertebral disc is a key element of the backbone, and most of the backbone pains are closely related to the disc functioning.
