The backbone occupies a central position in the musculoskeletal system. Holes vertebrae stacked one above the other form the spinal canal. Spinal cord passes through the spinal canal. The spinal cord is formed by a bundle of nerve fibers is based on the level of the cerebral cortex and send commands to it by the entire body. If intervertebral discs are not comprehensive, then narrows the intervertebral space, which can lead to nerve root compression. Damage to the spinal discs of the lumbar spine is called the lumbar discopathy. If the disc between the vertebrae deteriorates and does not interfere with any treatment he may break occurring herniated disc. It is often observed in the L4-L5 disc; L5-S1. The most common form is encountered intervertebral disc herniation, which can occur at any level but the most affected is the lumbar spine, and cervical and dorsal less.
