MODULAR ORTHOPEDIC IMPLANTS FOR ARM BONES BASED ON SHAPE MEMORY ALLOYS

The direction of our study was focused on the internal modular implants such as osteosynthesis plates, based on shape memory alloys. The proposed intelligent device is a modular bone plate with modules made of Titanium and staples made of Nitinol which present the following advantages: -minimal intervention and small size of the implanted foreign bodies, -the small incisions mean smaller risk of infection, - the force generated by the nitinol staples accelerates healing and reduces the time of bone recovery. Using CT numerical bone models, the mechanical simulation of the humerus osteosynthesis is presented using Finite Element Method. The stress and displacements diagrams for human humerus bone, for plate modules and for staples are presented.
