Scoliosis is a disease that spine is curved sideways when viewed from the front. Most of cause is idiopathic in adolescence. Scoliosis effect progresses thoracic deformity, affect the respiratory and cardiovascular. Early detection of scoliosis is important for patients. Ready-made diagnosis scoliosis research has exposure from X-ray or ambiguous evaluation. It is known to clinically that relationship of thoracic deformity and scoliosis are dynamically changed constantly by the respiratory motion. The detection system of the respiratory motion was developed but it detects only still image. Therefore it is difficult to obtain the relationship of the breathing and could not perform an accurate evaluation. Therefore we applied a finite element method for the 3D models of a backbone and costal of scoliosis patient. In this paper, we described a relationship between the breathing movement and the scoliosis from the result.
