Abstract

SE PRESENTA LA PIEZA MUSLERA DE TIPO FIJO PARA UNA ENDOPROTESIS DE LA ARTICULACION DE LA CADERA. LA PIEZA CONSTA DE UN MANGO QUE TERMINA EN PUNTA EN SU EXTREMO INFERIOR. EN EL EXTREMO SUPERIOR DE LA PIEZA SE HA CONFIGURADO UN APOYO (12) DE BRIDA. BAJO EL APOYO SE HA DISPUESTO UNA ANILLA (34) REGULABLE QUE AL MENOS CUBRE EN PARTE EL APOYO. EN EL EXTREMO SUPERIOR DE LA PIEZA SE HA REALIZADO UNA HENDIDURA (30). ES PREFERIBLE QUE ESTA HENDIDURA SE RAMIFIQUE EN OTRAS HENDIDURAS. TAMBIEN ES DESEABLE QUE LA HENDIDURA SE PROLONGUE HASTA EL EXTREMO SUPERIOR DEL APOYO Y SIRVA A LA FIJACION CON EL HUESO EN EL ESPACIO INTERMEDIO ENTRE EL HUESO Y LA PIEZA MUSLERA. TODO ESTO, UNA VEZ QUE LA PIEZA MUSLERA HA SIDO FIJADA AL HUESO
