The lower lumbar spine is affected, mainly for three reasons: 1, in the process of lower back, the pressure between the vertebrae will increase, which will easily lead to degeneration of the intervertebral disc, cracks or rupture of the fibrous ring, resulting in the nucleus pulposus being squeezed out, forming a herniated lumbar disc, which will compress the nerve roots of the lumbar region and cause radiating pain or numbness in the lower limbs. 2, is due to the process of lower back, resulting in the lumbar The ligaments, tendons, muscles and other soft tissues are overstretched and strained to form local strains, leading to the formation of sterile inflammatory lesions in the local area. The lower back can also lead to a decrease in the stability of the spine, ligaments can become more lax, and the presence of persistent inflammation can lead to hyperplasia, hypertrophy and osteophytes in the ligamentum flavum and the posterior longitudinal ligament, resulting in pain or spinal stenosis in the lower back.
