An apparatus for orienting a prosthetic femoral head rela-tive to an acetabulum comprises a femoral stem and a femoral head mem-ber. The femoral stem is configured to be received within the in-tramedullary canal of a femur. The femoral head member is configured to couple to the femoral stem and further configured to be received in the ac-etabulum. The femoral head member further comprises an indicia config-ured to orient a relative position of the prosthetic femoral head to the ac-etabulum such that the indicia signifies proper relative position of the prosthetic femoral head in the acetabulum.

La tige fémorale est configurée pour être reçue dans le canal intra-médullaire du fémur. L'élément de tête fémorale est configuré pour être relié à la tige fémorale et en outre configuré pour être reçu dans la cavité cotyloïde. L'élément de tête fémorale comporte de plus un indice configuré pour orienter une position relative de la tête fémorale prothétique par rapport à la cavité cotyloïde de telle sorte que l'indice signifie une position relative correcte de la tête fémorale prothétique dans la cavité cotyloïde.
