Scoliosis is a lateral or lateral bending of the spine. It usually starts in childhood or adolescence and may slowly get worse. The younger the age when scoliosis starts, the worse it will be. The degree of curvature is measured from the corner. The wider the angle, the greater the chance that scoliosis will be less than 30 degrees at the end of childhood. Growth rarely deteriorates and does not require close monitoring. If the curve is greater than 50 to 75 degrees, treatment may be required. More girls than boys have severe disorders.
