Lumbar disc herniation is a common disease in Department of orthopedics, the clinical incidence rate of 5%, is a common cause of low back pain. As early as in the "Yellow Emperor" on the introduction of the manipulation on low back pain. The ancient Greek "disease" has been used in this "sciatica" this noun [1-2]. In 1934 Mixter and Barr proposed the lumbar disc herniation and finds it become the main reasons of "sciatica" since the lumbar disc herniation has become one of the common disease in Department of orthopedics . 1 the etiology and pathogenesis of lumbar disc herniation is the most common lumbago disease, the disease occurs in young adults 20~50 years of age, male to female ratio was 4: 1. The patients with backleg pain outpatient surgery patients accounted for 50%, accounting for about 70% of the patients in the outpatient department of orthopedics. The lumbar disc herniation accounted for about 20% of patients with lumbocrural pain clinic. The intervertebral disc is the connection between the two vertebrae, which constitutes the weight-bearing joint of the spine. Each disc made of fiber ring, nucleus pulposus, cartilage is composed of 3 parts, with the increase of age and continue to suffer extrusion, traction, rotation and torsion force, intervertebral disc degeneration, reduce the water content of the nucleus gradually lose elasticity, intervertebral space narrowing, ligament relaxation or cracks, this is internal. Under the action of external force, such as bending extraction weight, disc back pressure increased, prone to rupture of fibrous annulus and nucleus posterior protrusion; a small number of patients with waist after cold, muscle tension increased to intradiscal pressure, intervertebral disc degeneration has helped to highlight.
