Scoliosis is a relatively common spinal disorder that can occur in children, adolescents, adults, and older adults at all times. Mild scoliosis is not easily detectable and often has no obvious symptoms, while severe scoliosis becomes more obvious in appearance, often with a twisted or skewed trunk, significant unevenness on both sides of the back, and different heights on both shoulders. Due to the curvature of the spine, it can cause changes in the force on the back muscles, imbalance of muscle strength on both sides, muscle spasm or weakness, resulting in back pain and affecting daily life. At the same time, severe scoliosis can cause a consequent change in the shape of the thorax, and the movement of the organs in the thorax, especially the lungs, is disturbed and restricted, affecting the respiratory function of the lungs, and some patients with severe scoliosis experience labored breathing for this reason. Severe scoliosis may also affect the spinal nerves traveling in the spinal canal, causing compression or stretching of the spinal cord and impaired nerve function, which may manifest as weakness, numbness or pain in the lower extremities. Therefore, for severe scoliosis, or scoliosis that develops rapidly, prompt consultation and early surgery are required.
