Now you can often hear such a diagnosis»Intervertebral hernia of lumbar department.» And it is on the lumbar region accounts for more than half of the cases of its occurrence. What is this disease, how it manifests itself, and what treatments are invented modern medicine against this disease?

A bit of anatomy

To imagine why could form a hernia intervertebral lumbar spine clarify the structure and lying in it structures.

The spine is composed of a plurality of vertebrae;almost drawn in a row, and this number, as the children's designer, has a few bends in the anterior-posterior plane. Each of them has a vertebral body - solid non-bone cylindrical shape. The vertebral bodies are interconnected intervertebral cartilage (aka - wheels) - of the structure, which is a substrate for the occurrence of a herniated disc. From the vertebral bodies depart in different directions several processes - small flat bones that form joints between them are not as difficult and smaller than those found between the bodies. This entire structure is strengthened with each other strong ligamentous apparatus: two main ligaments are the anterior and posterior surface of the vertebral bodies, the other firmly associated processes. But that is not all.

Between the body and shackle (a set of processes)vertebrae turns period. When comparing vertebrae to each other this hole turns into the spinal canal. It runs the spinal cord - the major structure that is responsible for the proper functioning of all the limbs and internal organs. It ends in the lumbar and sacral nerve bundles, resembling the tail of a horse (it is called, and is responsible for the innervation of the pelvic organs).

When connecting the processes of vertebrae in a single unit also gaps formed between them. bundles of nerves go through them - spinal roots, as well as blood vessels.

The substrate for the emergence of a herniaintervertebral disc. This structure consists of fibers resembling a tendon on the outside (this is called »fibrous ring») in the middle of the core is a soft jelly. It is called pulposus spine and provides cushioning function. The whole structure is surrounded by a special membrane, through which the differential pressure held and the water and nutrients. And this is the membrane properties thicken with age.

It is important to note that the lumbar spine isthe most vulnerable in the spine. Although he formed a powerful vertebrae, but it accounts for a very large load associated with the vertical position of the body, as well as the implementation of different kinds of physical effort, including - weight lifting. In addition, it is often the department is forced to balance the sloping basin, then curved toward the spine in scoliosis, not to mention obesity and disorders of posture when sitting.
