Abstract

SE MUESTRAN NUEVOS DISPOSITIVOS ORTOPEDICOS COMPUESTOS. EL DISPOSITIVO CONTIENE UNA PARTE EXTRAOSEA (11) FIJADA A UNA PRIMERA PARTE INTRAOSEA (12) QUE ESTA UNIDA A UN SEGUNDA PARTE INTRAOSEA (14); LA PARTE INTRAOSEA PUEDE ESTAR EN CONTACTO CON EL CANAL INTRAMEDULAR DEL FEMUR HUMANO. EL MODULO VARIA A LO LARGO DE LA LONGITUD DEL DISPOSITIVO, DISMINUYENDO DE LA PARTE EXTRAOSEA A LA SEGUNDA PARTE INTRAOSEA. LAS VARIACIONES EN EL MODULO SE CONSIGUEN FORMANDO EL DISPOSITIVO CON UN COMPUESTO QUE COMPRENDE FILAMENTOS DISPUESTOS NO LINEALMENTE A LO LARGO DE LOS EJES LONGITUDINALES DEL DISPOSITIVO Y DENTRO DE UNA MATRIZ DE POLIMERO. TAMBIEN SE MUESTRA EL METODO DE FABRICACION DEL PRESENTE DISPOSITIVO ORTOPEDICO.
