Abstract

UNA ESTRUCTURA DE FUSION 20 PARA LA FUSION DE UN CUERPO VERTEBRAL QUE TIENE FORMA CONICAS. SE FORMA UNA ROSCA 40 COMO PARTE DE LA SUPERFICIE CONICA EXTERIOR DE LA ESTRUCTURA DE FUSION. SE DEFINEN UNAS APERTURAS 54 A TRAVES DE LA ESTRUCTURA DE FUSION PARA QUE SE PUEDA ESTABLECER UN CONTACTO ENTRE LAS ESTRUCTURAS OSEAS VERTEBRALES ACOPLADAS Y UNAS SUSTANCIAS INDUCTORAS DEL CRECIMIENTO DE LOS HUESOS QUE HAY EMPAQUETADAS EN LA ESTRUCTURA DE FUSION. LA ESTRUCTURA DE FUSION SE INTRODUCE Y MANTIENE O AUMENTA LA LORDOSIS ENTRE LAS ESTRUCTURAS OSEAS VERTEBRALES ADYACENTES.
