The left thoracic cage had fallen into the same side pelvis. The body balance cannot be sustained. She was very easily to fall down when standing at attention and also had moderate restrictive ventilatory disorder and severe obstructive ventilatory disorder. In the peroperation assessment, the Cobb measuring was 145˚and thoracic vertebrae bodies were 90˚rotation to the right side.
