有限要素法による頸椎症治療に用いるスペーサの選定と構造上の力学的検討について

抄録

In this study, we focused on open cervical dilatation (following single opening method), which is safe and easy to perform during laminoplasty as a treatment for cervical spondylosis. Though the single opening method has been established as an operative method, there is a present state that the selection of the spacer for maintaining the fist arch of vertebra and the cutting quantity depend largely on the experience of the doctor. See you. There are few examples of mechanical examination on the difference in structure by the difference of the spacer in the postoperative stage. Therefore, a finite element model of the cervical spine from C1 to C7 was made from the tomographic images of the cervical spine in this study. And, the dynamic examination of cutting quantity and selection of the spacer was carried out for the model made.
