Abstract

CAZOLETAS ARTIFICIALES DE ARTICULACION DE CADERA, CON UNA SUPERFICIE EXTERIOR SINUOSA, CON UNA PARTE ANTERIOR PARCIALMENTE ESFERICA Y UNA PARTE POSTERIOR CON UN ROSCADO EXTERIOR AUTOCORTANTE. LA PARTE POSTERIOR (3) TIENE FORMA CONICA. EL ROSCADO EXTERNO (4) SOBRESALE DE LA SUPERFICIE ESFERICA HACIA FUERA, QUE ESTA PENSADA COMO AMPLIACION DE LA PARTE PARCIALMENTE ESFERICA (2). LAS ESCOTADURAS QUE FORMAN LOS BORDES DE CORTE DEL ROSCADO EXTERIOR AUTOCORTANTE (4) SE ALARGAN POR LO MENOS HASTA LA SUPERFICIE ESFERICA AMPLIADA. EL ROSCADO EXTERNO (4) SE FABRICA DE FORMA SENCILLA. A PESAR DE ELLO SE CONSIGUE UNA FUERTE UNION DESPUES DEL ROSCADO EN TODA LA ZONA EXTERNA. TAMBIEN ES VALIDO PARA EL CASO EN QUE EL NUCLEO SOBRESALGA AL MENOS PARCIALMENTE DE LA SUPERFICIE ESFERICA PENSADA COMO AMPLIACION. DEBIDO AL CARACTER AUTOCORTANTE EL NUCLEO DEL ROSCADO CONSIGUE EL MISMO SU FORMACION COMPLEMENTARIA EN EL HUESO DE LA CADERA.
