| Outline of Final Research Achievements |
The analysis of finite element model was performed using the load increment method with the osteoporotic vertebral body fracture. The model which had smaller rod stiffness showed suppression of microfracture in the vertebral body and reduction of the stress concentration. Semi-rigid stabilization for osteoporotic vertebral fractures might have a potential to prevent loosening of pedicle screw or the incidence of fracture.
