Abstract

EL ELEMENTO (20) DE ACUERDO CON LA INVENCION SE COMPONE DE UN CUERPO BIODEGRADABLE, QUE SE ENCAJA ANTES O DURANTE LA IMPLANTACION DE UNA PROTESIS (1) ORTOPEDICA DE TAL MODO QUE EN UNA CAVIDAD (2) DE LA PROTESIS (1) SE ELEVA LA RIGIDEZ DE ESTA PROTESIS. EL ELEMENTO (20) EFECTUA UNA UNION MECANICA ENTRE LOS ELEMENTOS (1A, 1B, 1C) DE CUBIERTA TAN PRONTO COMO EL ELEMENTO (20) EJERCE UNA FUNCION DE APOYO, QUE REDUCE LAS PROPIEDADES ELASTICAS RESPECTIVAS EN LAS POSIBILIDADES DE MOVIMIENTO DE LA CUBIERTA (1) EXTERIOR. LA CAPACIDAD DEL ELEMENTO (20) PARA SU BIODEGRADABILIDAD EN LA TRANSMISION DE FUERZA SE REDUCE UNA VEZ QUE SE INCREMENTA LA IMPLANTACION SUBSIGUIENTE, DE TAL MODO QUE LA CUBIERTA (1) EXTERIOR DE LA CAVIDAD DE ARTICULACION DE CADERA ARTIFICIAL, DE FORMA CORRESPONDIENTE A LAS PROPIEDADES MECANICAS, SEGUN LAS CONDICIONES CONSTRUCTIVAS, MUESTRA PROPIEDADES ELASTICAS EN AUMENTO. DESPUES DE UNA SUJECION TEMPORAL CONOCIDA SEGUN LA IMPLANTACION SE DESINTEGRA DE FORMA BIOLOGICA EL ELEMENTO (20), DE MODO QUE YA NO TRANSMITE NINGUNA FUERZA.
