Abstract

RESUMEN La invención se refiere a un casquillo de unión para vástagos de anclaje de dos prótesis dispuestas de manera opuesta, preferiblemente en un hueso largo como el fémur o húmero. El casquillo de refuerzo comprende dos manguitos de recepción (1, 2) para en cada caso un vástago de prótesis y una zona de acoplamiento (3) separable dispuesta en medio para la unión resistente al deslizamiento y al giro. Según la invención los manguitos de recepción (1, 2) presentan en su lado dirigido hacia la zona de acoplamiento en cada caso una horquilla (31, 32) de un par de horquillas que actúan conjuntamente entre sí, y en un pie de la horquilla está dispuesto un bloque de ajuste (4), cuyas superficies laterales (44) presentan una distancia tal que corresponde a una anchura interior de la horquilla, y las superficies laterales (44) están configuradas para el apoyo plano en flancos de la horquilla, estando dispuesto al menos un tornillo de fijación (5) transversalmente a través de la horquilla. La unión de horquilla es más sencilla de fabricar que la unión de cuña conocida y aun así es lo suficientemente robusta. A diferencia de la unión de cuña no es necesario un ajuste exacto; en principio es suficiente un ajuste holgado entre la horquilla (31, 32) y el bloque de ajuste (4), eliminándose una holgura excesiva mediante el tornillo de fijación (5).
