Outline of Final Research Achievements

The positive effect on bone fusion using the combination of PRP and the gelatin β-TCP sponge is equivalent to that of autogenous bone grafting.
We also study the process of bone repair in a vertebral body defect model in order to use this biomaterial in vertebroplasty.
This method might be less invasive than autogenous bone grafting in terms of being able to induce bone fusion by autologous blood without impairing of healthy donor site. This method also has the advantage of being very safe to perform, because all these materials have already been extensively used clinically. The current study demonstrates that the bone fusion method using the combination of PRP and the gelatin β-TCP sponge could be an alternative to autogenous bone grafting in terms of its effectiveness, lower invasiveness, and safety.
