| Outline of Final Research Achievements |
In recent years, the importance of trunk muscles for maintenance of good posture has been emphasized to achieve a healthy lifestyle. The purpose of this study is to understand the relationship between the functional anatomy of the iliopsoas muscle (an important trunk muscle) and spinal alignment and to establish a safe surgical technique for spinal deformity correction. Research has shown that the iliopsoas muscle moves forward more than usual as the spinal deformity progresses, and once the spinal deformity correction surgery improves spinal alignment, the iliopsoas muscle moves backward to its original position while carrying out its original function. This provides evidence that it may be possible to improve and maintain a good posture. In addition, effective procedures during spinal deformity correction surgery and clinical features that should be noted before surgery have been clarified.

| Academic Significance and Societal Importance of the Research Achievements |
健康寿命延長のため、良い姿勢を長く保持することは重要である。筋肉はその作用方向で機能が決まる。本研究により姿勢を保持する体幹筋として重要な腸腰筋の位置は脊椎アライメントに応じて変化することが明らかとなった。日常の姿勢に注意することに加え、手術によって良好な脊椎アライメントを獲得することで腸腰筋機能を最大限に発揮することができ、これを一般に広く認知していただくことで、本研究の成果は健康寿命の延長に寄与する。また、安全な脊柱変形矯正手術の確立のために新たな知見を与えた。
