The knowledge how scoliosis affects the respiratory function is important for the treatment of scoliosis. This study investigates the effect of scoliosis to respiratory function using the developed simulation model of scoliosis based on individual CT/MR images. Individual model of scoliotic rib cage is formulated by FEM software (Ansys, ver6.1), to simulate the activity of the exterior and interior inter-costal muscles relating the respiratory motion .The calculation procedure of the volume change of rib-cage under respiratory motion using nodal coordinates and nodal displacements was shown. The rib-cage volume change in respiration of scoliotic subject became considerably less than that of healthy. The investigation of respiratory function relating to rib-cage volume change of scoliotic subject gives a suggestion for the treatment.
