AI 要約（直近 5 年の研究成果）

Okada研究室は脊椎疾患の外科的治療と関連する臨床上の課題を中心に研究を行っています。特に側弯症、脊椎変形、脊髄圧迫などの脊椎疾患の患者に対する手術治療の成果向上と、手術に伴う合併症の予防・軽減を目標としています。脊椎後方筋肉の経年変化や骨粗鬆症患者の体格が手術成績に与える影響など、患者背景と治療成績の関係を調べることで、より効果的で安全な治療戦略の構築に取り組んでいます。主な研究手法としては、長期的なMRI追跡調査による脊椎周囲筋肉の形態学的変化の評価、ならびに過去の手術患者のデータを統計的に分析するレトロスペクティブスタディを採用しています。これらの研究を通じて、脊椎変形矯正手術後の肩のバランス喪失や偽関節形成といった合併症の危険因子を特定し、手術方法や周術期管理の改善に向けた知見を得ています。さらに脊髄空洞症や脊髄圧迫を伴う複雑な脊椎疾患の手術戦略についても検討を進めており、脊椎疾患患者のQOL向上に貢献する臨床研究を展開しています。
