Scoliosis is actually not a diagnostic term; it is a descriptive term for a symptom. Scoliosis is the common name for scoliosis, a three-dimensional deformity of the spine that includes abnormal alignment in the coronal, sagittal and axial planes. Our normal spine is straight when viewed from the front and has three physiological curves when viewed from the side: anterior convexity of the cervical spine, posterior convexity of the thoracic spine, and anterior convexity of the lumbar spine. If the two shoulders are asymmetrical from the front, curved to one side, or the physiological lordosis increases, and the physiological curvature disappears from the side, the abnormality is considered scoliosis, and a physical examination should be performed at a hospital to take a full frontal and lateral spine x-ray in the standing position. Mild scoliosis usually has no obvious clinical symptoms and no obvious deformity is visible in appearance. Severe scoliosis can affect the growth and development of infants and adolescents, deforming the body and seriously affecting cardiopulmonary function, involving the spinal cord and even causing paralysis. Mild scoliosis can be observed and followed up to see what happens next, while severe cases require surgery. Adolescent scoliosis is a common disease that harms adolescents and children, and the key is early detection, early treatment, and early prevention.
