Disc herniation is a protrusion formed in the intervertebral discs as a result of significant efforts or jerky or repetitive. These protrusions or hernias compress the nerve roots exiting the spine and go to the arms or legs. For the neck, herniated cervical disc produce the so called "Cervico-Brachial Neuralgia (pain in the neck, shoulder and arm on the side of the hernia) and in the case of the lumbar produce sciatica or lumbo-sciatica or pain in the lower back, and this pain spreads to the leg-side herniated lumbar or lumbo - sacral.
Herniated disks can occur in Cervical or lumbar level.
Herniated lumbar intervertebral discs are cartilaginous plates surrounded by a fibrous ring which lie between the vertebrae and serve to cushion. For, wear and tear or trauma, the fibrous tissue (annulus) that surrounds the soft disc material (nucleus pulposus) may tear. This causes the disc protrusion or extrusion of disc material into the canal or neural foramen. This has been called herniated discs, ruptured discs, nucleus pulposus, or prolapsed disc.
In herniated lumbar spine intervertebral disc herniation is a Cando often found weakness in the fibrous ring that surrounds the disk, whereas in the lumbar nerve roots are only at the level of the cervical spine cervical spinal cord there and this can also be compressed by the herniated disk.
Radiographic evaluation of suspected spinal condition begins with an x-ray A herniated disc, being composed of soft tissue instead of bone are not visible on X-rays, but can appreciate other associated changes, such as the characteristic bony ridges of cervical spondylosis. Also, can be accurately align the disks.
