Caracterização de uma haste femoral de Ti-6Al-4V não cimentada

Abstract: ResumoO objetivo deste estudo foi determinar a viabilidade de produção de uma prótese femoral de titânio garantindo a qualidade da matéria prima e as características das superfícies. Um protó-tipo foi criado pelo Método de Elementos Finitos em AutoCad ® 2000. A simulação dos esforços demonstrou uma tensão de von Mises 8,1 vezes menor que a tensão crítica para escoamento do material. Na determinação dos constituintes metálicos, obtevese: Fe = 0,06%, Al = 6,20%, V = 3,57%, O = 0,115%, N = 0,003%, H = 0,010%, e a… Show more

“…Both medical and biomechanical point of view is necessary to develop new methods of implant selection. Clinical trials focus mainly on infection prevention and loosening of endoprosthesis stem, while biomechanics focuses on such things as wrong deformation relations in the composition bone -endoprosthesis, lack of biocompatibility, interference of implants on bone tissue, development of modern implant models and influence of constructional parameters such as: stem stiffness, its length or shape [1][2][3].…”
