Abstract
Ni–Ti
alloys are used in bioengineering applications as they join important
qualities as resistance to corrosion, biocompatibility, fatigue
resistance, MR compatibility, kink resistance with two unique
thermo-mechanical behaviors: the shape memory effect and the
pseudo-elastic effect. The adaptive modular implants based on smart
materials represent a superior solution in the osteosynthesis of the
fractured bones over the conventional implants. To realize the model of
the modular plate we used SolidWorks software. The small sizes of the
modules enable the surgeon to make small incisions, using surgical
techniques minimally invasive, having the following advantages:
reduction of soft tissues destruction; eliminating intra-operator
infections; reduction of blood losses; the reduction of infection risk;
the reduction of the healing time. Numerical simulations of the
assembly humerus bone- modular implant are realized using
Visual-Nastran software. The Von Misses stress diagrams and the
displacements diagrams are obtained.
