| Outline of Final Research Achievements |
Scoliosis is a sideways curvature of the spine and surgical treatment for the scoliosis imposes economical and physical burdens for patients. Therefore, there is a demand for less invasive surgical techniques. In this study, we conducted experimental and analytical investigations to obtain fundamental insights necessary to achieve optimal and minimally invasive surgical methods for scoliosis. As a result, we quantitatively assessed spinal stiffness, established a model experiment method applicable to clinically used surgical devices, and confirmed the availability of our proposed surgical methods compared to conventional approaches through computer simulations.

構造的にも機能的にも複雑な機構を有する人体の脊椎について定量的な検討を行うためにはその機構を適切に模擬する必要がある。本研究で実現した成長過程にある脊椎を表現可能な模型は世界的にも例がなく、早期発症側弯症に対する手術手法を検討するためのデバイスとして重要性は高い。さらに、解析的にも成長を加味した手術シミュレーションを実現し、学術的な意義が大きい。また、本研究で確認した効果的な手術手法を用いることにより、側弯症患者の合併症リスクの低減や医療費の削減が期待される。
