For the elderly, the atrophy of intervertebral disc will lead to shorter height. When the spine moves, the intervertebral disc has the characteristics of wedge-shaped deformation and horizontal movement of the nucleus pulposus, so when rotating or bending sideways, the intervertebral disc is squeezed and thinned on the same side, and at the same time the opposite side is subjected to tension, tension and torsion.
When this force exceeds the stress capacity of the intervertebral disc, it will damage the annulus fibrosus and make the nucleus pulposus overflow. The overflowing nucleus pulposus protrudes into the intervertebral foramen or spinal canal, which will compress the spinal nerve roots and lead to a series of symptoms of disc herniation.

Common diseases and treatment
1. Lumbar disc herniation is one of the most common causes of low back and leg pain in clinic. There are many treatments for lumbar disc herniation, which can be roughly divided into three categories: surgical treatment, conservative treatment and percutaneous treatment.
2. Conservative treatment is mostly individualized treatment, including: bed rest, local manipulation, hot compress, traction, physical therapy and back muscle exercise; Mannitol dehydration in acute stage; Oral painkillers, non-steroidal anti-inflammatory drugs, neurotrophic drugs, etc.
Percutaneous treatment technology is a kind of treatment method between surgical treatment and conservative treatment, which mainly includes chemical nucleolysis, laser disc decompression (PLDD), percutaneous endoscopic laser discectomy (PELD), intervertebral disc electrothermal therapy (IDET) and epidural hormone injection therapy.
3. Minimally invasive treatment has the advantages of less trauma, good curative effect, less bed rest time, less complications, less damage to the stability of spinal cord, less pain for patients and quick recovery.
It has become a new trend in the treatment of lumbar disc herniation, but minimally invasive treatment requires surgeons to have rich clinical experience and minimally invasive surgical skills, and strictly select their indications according to the characteristics of various minimally invasive operations in clinical practice in order to obtain satisfactory results.
