The invention relates to a mixed acetabular implant with attached fastening tabs According to a characteristic of the invention, the surface of the cup (1) delimits a zone (1c) of positioning and angular orientation in the acetabular cavity. This fixation zone (1C) allows, during the impaction in the acetabulum cavity of the iliac bone, a tight intimate fit also called press fit. This zone is composed of asperities and depressions in relief almost parallel to the equatorial plane. The cup has arrangements for mounting, if necessary, members reported in the form of legs and / or stability hooks. According to a first embodiment these arrangements are regularly distributed on the outer surface of the cup and are constituted by cavities (1d1) and a latching system (channel or groove) (1s2) .Every cavity (1d1) has a profile determined in addition to the groove (1d2) to create a coaptation in combination with a complementary profile of a base (4a) of the attachment or anchoring member (4) (lugs, hooks, ...) Each cavity (1d1) is oriented to allow mounting of the attachment or anchoring member (4) (legs, hooks, ...) by its base (4a) from the polar zone of the cup and before his impaction. Each cavity (1d1) is oriented upwards. L'invention concerne un implant cotyloïdien mixte avec pattes de fixation rapportées Selon une caractéristique de l'invention, la surface de la cupule (1) délimite une zone (1c) de positionnement et d'orientation angulaire dans la cavité cotyloïdienne. Cette zone de fixation (1C) permet lors de l'impaction dans la cavité cotyloïdienne de l'os iliaque, un ajustement intime serré appelé aussi press fit. Cette zone est constituée d'aspérités et de creux en relief quasiment parallèle au plan équatorial. La cupule présente des agencements pour le montage, si nécessaire, d'organes rapportés sous formes de pattes et/ou crochets de stabilité. Selon un premier mode de réalisation ces agencements sont régulièrement répartis sur la sur
