Abstract
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 1m 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 PVIMA is highly concentrated on the top-front of trabecular bone of compressed vertebra.
