脊椎脊髄外科における合併症回避のための術前シミュレーション

Preoperative Simulation for Complication Control in Spinal Surgery

Point

・頭蓋頚椎移行部は延髄，上位頚髄，椎骨動脈といった重要な構造物を含み，かつ頚部の屈曲，伸展，回旋といったダイナミックな動きをつかさどる．

・特に，頭蓋底陥入症の手術ではしばしば固定術が必要となるため，綿密な術前シミュレーションが必須となる．

・3Dボーンモデルの作成・利用は，手術シミュレーションに非常に有用である．

　The craniovertebral junction not only contains anatomically important structures such as the medulla oblongata, upper cervical spinal cord, and vertebral artery, but also controls the dynamic movements of flexion, extension, and rotation of the head and neck. Consequently, instability and spinal deformities can easily occur in the craniovertebral region, and appropriate treatment should be selected based on the specificity of the lesion. Basilar invagination often involves bone and vascular anomalies and fusion surgery is often required. Therefore, careful pre-operative simulations are necessary. The creation and use of three-dimensional bone models, including image navigation, are useful for surgical simulation.
