| Abstract Scope |
Few researchers have developed porous biomaterials to tackle the stiffness of the bulk materials and offer low stiffness to match the properties of the bones. Finite element models of body-centered cubic (BCC) porous structures with a porosity of 70% are filled with polyglycolic acid (PGA) to prepare the composites. The composite of the Ti-PGA BCC structure is modeled in SOLIDWORKS. The composite cubes were imported in ABAQUS to simulate the compressive properties. A fracture gap size of 3 mm was introduced and a number of bi-cortical screws are used to assemble the fractured bone and implants (composite and dense titanium). The results shows that the BCC composite cube gave lower mechanical properties as compared to the dense titanium stems. The stiffness of the healed fracture increases in the case of larger size of the callus. |
