Lumbar disc herniation is also known as “rupture of the lumbar disc annulus fibrosus”. It is a common disease of the lumbar region, mostly occurring in young adults between the ages of 20 and 50, and is especially common in heavy laborers. The intervertebral disc is the connecting part of the vertebral body and has the function of stabilizing the spine and cushioning shock. With the growth of age and constantly subjected to extrusion, traction and torsion and other external forces, the intervertebral disc degenerates and loses its elasticity, thus narrowing the intervertebral space and loosening the surrounding ligaments, resulting in instability of the vertebral body, which is the internal cause of lumbar disc herniation; while trauma and wind, cold and dampness are the external causes of the disease. This disease mostly occurs between lumbar 4-5 and lumbar 5-sacral 1. 1.Lumbar and leg pain: lower back pain as well as lower limb radiological pain, both of which may appear at the same time, or lower back pain may appear first and lower limb radiological pain may appear after several days or weeks. 2. Unfavorable movement of the lower back. 3.Changes in spine morphology: scoliosis, reduction or disappearance of lumbar physiological anterior convexity, or posterior arch in severe cases. 4.pressure point: mostly found in the lumbosacral region with obvious pressure pain and radiating to the lower belly. 5.When the affected limb is elevated with straight legs in supine, there will be increased pain in the lower limbs, and in severe cases, the lower limbs can only be elevated 150°-30°. 6.Decreased dorsiflexion or plantarflexion of the bunion.
