Outline of Final Research Achievements

Bone microstructural analysis by high-resolution CT (HR-pQCT) was performed on 140 Japanese women over the age of 50, and the factors involved with cortical bone porosity were analyzed.
Cortical porosity occurred more frequently in cases where trabecular bone was preserved in this study.
This result is a new finding in the research of osteoporosis and may become a basis for proposing a new hypothesis on the mechanism on bone deterioration.

Academic Significance and Societal Importance of the Research Achievements

皮質骨多孔性は、通常の臨床用画像装置では検出することができないが、骨脆弱性を引き起こす骨構造の重要な因子である。
本研究で、皮質骨多孔性の発生メカニズムの糸口が見つかり、かつ、今後さらに、皮質骨多孔性と、日常診療で知り得る患者情報との関与を探索することで、骨折リスク評価や骨折予防へ貢献できると考えられる。
