| Outline of Final Research Achievements |
A new minimally invasive osteosynthesis plate was developed. Dimples for facilitating bone fragment reduction / temporary fixation operation were machined into conventional plates. Since there was concern that the rigidity of the plate might be decreased by machining, the following three kinds of experiments were conducted; 1) computer simulation by the finite element method, 2) actual rigidity test, and 3) stress concentration by the stress emission experiment .
As a result, the reduction in rigidity due to dimple formation was around 7%. Furthermore, this value was much lower than the reduction in rigidity when the plate size was increased.
In conclusion, "dimple pate" was considered that the new osteosynthesis plate produced by the dimple could be applied clinically.
