L4-L5 disc bulge, the horizontal spinal canal and both sides of the intervertebral foramina slightly narrowed cause of lumbar disc herniation. In this case of lumbar disc herniation, degenerative disc disease is the underlying cause. As the lumbar discs are subjected to greater pressure in the spine and loads, the discs undergo degenerative disease as they age. Under the action of external forces, strain accumulation, in which the annulus fibrosus and nucleus pulposus gradually decline in water content, lose elasticity, rupture, nucleus pulposus, annulus fibrosus can be protruding backward, which leads to disc bulging level of the spinal canal and both sides of the foramen magnum, and in severe cases, there are also symptoms of compression of the nerve. Patients with this symptom will have lumbar pain and sciatica, limited lumbar movement, and lumbar scoliosis. Clinically, 80% of patients can be relieved and cured by non-surgical treatments, and appropriate treatment options should be selected under the guidance of a physician.
