Abstract

LA PATENTE DESCRIBE UN ELEMENTO (1) ANATOMICO QUE SE UTILIZA PARA LA COLOCACION DE UNA ENDOPROTESIS ARTICULADA O DE LA ARTICULACION DE LA CADERA, Y TIENE UN ELEMENTO (10) ANATOMICO EXTERIOR VUELTO HACIA EL HUESO DE LA CADERA, Y UN ELEMENTO (20) INTERIOR DISTANCIADO RADIALMENTE DEL ANTERIOR, SOPORTANDO EN EL LATERAL DE LA ARTICULACION, UN INLAY (40) PARA LA ARTICULACION ESFERICA. LA INVENCION SE CARACTERIZA PORQUE: EN EL LATERAL EXTERIOR DEL ELEMENTO (10), ESTAN PREVISTOS UNOS TRAMOS (12) DE PASO DE ROSCA SITUADOS EN LA PERIFERIA DEL LATERAL, Y SEPARADOS RADIALMENTE ENTRE SI; LOS TRAMOS (12), SE DISPONEN EN SERIE (13) Y SE INTERRUMPEN POR RANURAS (11) TRANSVERSALES A LOS MECIONADOS TRAMOS, Y ANGULARES CON RESPECTO AL EJE DE ROSCADO. SE FORMA UNA ROSCA CORTANTE DE ATORNILLADO EN EL HUESO DE LA CADERA; EN EL ELEMENTO (10) ANATOMICO EXTERIOR, SE DISPONEN VARIOS HUECOS QUE SE DISTRIBUYEN POR LA SUPERFICIE DE DICHO ELEMENTO Y TIENEN FORMA DE APERTURAS (11) LONGITUDINALES, LAS CUALES UNEN UN ESPACIO INTERMEDIO (50) CONFORMADO ENTRE EL ELEMENTO ANATOMICO (20) Y EL ELEMENTO (10) (EN EL CUAL SE APOYA EL HUESO DE LA CADERA). SE INSTALAN SUSTANCIAS OSEAS EN EL ESPACIO INTERIOR, Y LAS RANURAS (11) SE CONFORMAN COMO APERTURAS LONGITUDINALES EXTENDIDAS POR TODA LA ALTURA DEL ELEMENTO (10) DE FORMA TRANSVERSAL A LA PERIFERIA DE DICHO ELEMENTO, PARA POSIBILITAR DESPUES DE LAS IMPLANTACIONES SUCESIVAS DE LA ENDOPROTESIS, UN ABASTECIMIENTO DE SUSTANCIAS OSEAS Y UNA MAYOR INTRODUCCION DE LA NUEVA SUSTANCIA OSEA EN LA CADERA.
