| Outline of Final Research Achievements |
The purpose of this study was to reveal bone strength prediction in the bone union process. The first study was achieved to establish predicting the in situ strength of the bone with implantation of bone plates by cadavers with using nonlinear finite element analysis(FEM). The second one was achieved to identify of material properties of the immature bone of the bone union process by rabbits. The last one was achieved to evaluate the dynamic influence that an implant gave to a bone in the long-term period after surgery by patients. As results, by the first study, the predicted bone strength in the simulated by FEM with implants was significantly higher than mechanical test measurements. By the second study, we could reveal some material properties of the immature bone of the bone union process. By the last study, we could reveal that in long term period after surgery, the locking plate decreased bone density than the conventional plates.
