The invention relates to a hip-joint prosthesis comprising a shaft (3) that can be inserted into the femur, the surface of said shaft being provided with an osteoinductive agent. Said agent is provided exclusively in the metaphysial section (5) of the shaft (3) and laterally in relation to the line (7) of the greatest anterior-posterior dimension of the shaft cross-section. The metaphysial spongiosa is thus more effectively integrated into the distribution of forces, without detrimentally affecting the re-operability of the prosthesis.
L'invention concerne une prothèse d'articulation de la hanche comportant une tige (3) à insérer dans l'os de la cuisse, la surface de cette tige étant pourvue d'un agent ostéoinducteur. L'invention est caractérisée en ce que cet agent ostéoinducteur se trouve exclusivement dans la partie métaphysaire (5) de la tige (3) et latéralement à la ligne (7) de plus grande dimension AP de la section transversale de la tige. Ainsi, l'os spongieux métaphysaire est mieux intégré dans le flux de force, sans nuire à l'aptitude à la réopération de la prothèse.
