Abstract

patente de invenção: "dispositivo intercorporal compósito e método de fabricação". a presente invenção refere-se a um dispositivo intercorporal compósito que inclui placas de extremidade superior e inferior com um núcleo de plástico moldado entre as mesmas. o núcleo inclui um ou mais rasgos de kmodo a permitir um crescimento ósseo através do núcleo. cada placa de extremidade inclui um lado de interface de osso revestido com hidroxiapatia, de modo a promover um osso em crescimento. os poros nos lados de interface de osso permitem um crescimento ósseo. os lados de interface de núcleo das placas de extremidade incluem poros relativamente maiores a fim de receber o material fundido do núcleo, por exemplo, durante uma moldagem por injeção, a fim de aumentar a ligação das placas de extremidade com o núcleo. cada placa de extremidade tem uma camada de barreira central a fim de impedir que o material de núcleo fundido venha se extrusar através dos poros de interface de núcleo nos mporos de interface de osso, preservando os poros de interface de osso para a reconstituição óssea. um método de fabricação do dispositivo intercorporal compósito é igalmente apresentado.
