Abstract：
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.
摘要：
颅骨交界处不仅包含解剖学上重要的结构，例如延髓，上颈脊髓，和椎动脉,而且还控制屈曲的动态运动，扩展,头部和颈部的旋转。因此,不稳定和脊柱畸形很容易发生在颅骨区域，应根据病变的特异性选择适当的治疗方法。基底内陷通常涉及骨和血管异常，通常需要进行融合手术。因此,仔细的术前模拟是必要的。三维骨骼模型的创建和使用，包括图像导航，对手术模拟很有用。
