The disease develops insidiously during growth. At the beginning, there are usually no symptoms; pain only occurs as the spine becomes increasingly bent. In the majority of children affected, the scoliosis regresses in the course of the disease, so that no treatment is necessary. However, if the disease progresses, there is increasing pain and malpositioning of the upper body. If left untreated, this can have serious consequences, such as reduced respiratory function due to the restricted development of the lungs or painful contact between the ribs and pelvic bones.
