척추성형술 시술에서 PMMA주입에 대한 흉추의 생체역학적 평가

초록

In this study, method of PMMA injection is suggested for vertebroplasty in patients with osteoporotic compression fracture. The finite element analysis is used to investigate the vertebroplasty quantitatively. In order to improve previous works with simplified geometry of vertebral body more exact geometry has been constructed from CT image data with 1mm thickness. An ideal method of PMMA delivery, with respect to location and amount of injectate, into vertebral body has been suggested based on evaluation of the insert positions and the insert shapes of injected PMMA. It is shown that vertebral body can be compensated most efficiently when PMMA is highly concentrated on the top-front of trabecular bone of compressed vertebra.
