Scoliosis needs to be treated, so why is there a natural curvature in the cervical and lumbar spine? The term “natural curvature” refers to the fact that the spine is seen in a straight line in the frontal position, while the natural curvature is required in the lateral position. What is associated with lumbar spine slippage? The physiological curvature of the cervical and lumbar spine (referred to as vertebral curvature) is formed by the need to maintain the balance of the central axis of the spine after standing and walking. As development matures, the vertebral curvature determines the following: 1. the sequence of spinal vertebrae. 2, the dynamics of the intervertebral discs. 3, the volume of the spinal canal. 4, the size of the intervertebral foramen. 5, the spinal cord, spinal nerves and the length of the attached muscle ligaments. 6.The position of each organ in the body. The severity of the symptoms of lumbar spondylolisthesis is related to the following factors: 1. whether the physiological curvature of the spine is within the normal range. 2.The degree of slippage. When the degree of slippage is small, only I degree or between I degree and II degree, and does not affect the nerves, blood vessels and other tissues, the corresponding symptoms will not appear. Therefore, as long as the degree of slippage is small and the physiological curvature is within the normal range, the relationship between the relative positions of the nerves and blood vessels in the spinal canal and intervertebral foramen is not affected, clinical symptoms will not occur. However, at the same time, it should be understood that the slipped vertebral body is like a “bomb” buried in the body, if the factors that make the vertebral curvature change, that is, the “fuse” appears, the normal relationship between the vertebral canal and the relative position of the nerves and blood vessels in the intervertebral foramen will be changed, and in This also makes the lumbar spondylolisthesis a lumbar spondylolisthesis, which shows how important it is to restore and maintain the physiological curvature of the spine.
