Zusammenfassung:Femoral implant (1) is forged and does not require machine finishing, mainly around neck (2). This forging method ensures the material continuity around neck, between tapered shank (3) and top section (11) so that mechanical strength of neck is increased in its weakest area. Neck has elliptic cross-section so as to also optimize its mechanical strength. L'implant fémoral pour prothèse articulaire de hanche comportant une tige (1) reliée par un col (2) à un cône (3) d'une tête de coopération avec un implant cotyloïdien, la tige (1) comportant une partie métaphysaire (11) à partir de laquelle s'étend le col (2) qui possède une largeur inférieure à la hauteur du col (2), est caractérisé en ce que l'implant fémoral (I) est une pièce forgée sans reprise d'usinage notamment au niveau du col (2).
