| Research Abstract |
In this study, the quantitative method to evaluate the geometrical symmetry for excessive deformation of the scoliosis was developed. Using thin-plate spline method, symmetrical spinal shape was restored from the original scoliotic shape. Compared the symmetrical shape with the original scoliotic shape, spatical strain distribution covering the scoliosis was evaluated. As a result, compress/tensile/shear stresses were observed. Therefore, the method was useful to quantify three dimensional strain distributions. Also, the method should be a novel approach to elucidate the bony complicated deformation.
