The spine is divided from top to bottom into cervical, thoracic, lumbar, sacral and caudal vertebrae, and the entire sacral vertebrae are basically fused together during growth and development, and the caudal vertebrae are also basically degenerated, and the largest part of the functions of the human spine are concentrated in the cervical, thoracic and lumbar vertebrae, which is also a relative sense. The entire spine has a special physiological bend, such as the cervical spine has a forward physiological bend, the thoracic spine has a slightly backward physiological bend, and the lumbar spine also has a forward physiological bend. The special anatomical structure can meet the body’s weight-bearing walking and preserve the maximum activity of the entire spine at certain special stages, such as the cervical and lumbar spine is the largest range of motion. Therefore, the human cervical and lumbar spine is very prone to disease changes, such as cervical spondylosis and lumbar spondylosis are very common in clinical practice.
