A method positions a profile of a pros-thetic component on the three-dimensional model of a limb. Patient-specific anatomical data of the limb is gathered. First and second anatomical landmarks are identified to determine a first spatial relationship. A third anatomical landmark is identified to determine a second spatial relationship with respect to the first spatial relationship. The profile of the prosthetic com-ponent is positioned in all but one degree of freedom. A fourth anatomical landmark is identified to position the profile of the prosthetic component in the one re-maining degree of freedom.

L'invention concerne un procédé de positionnement du profil d'un composant prothétique sur le modèle tridimensionnel d'un membre. Les données anatomiques particulières d'un patient sont recueillies. Des premier et second points de repère anatomiques sont identifiés pour déterminer une première relation spatiale. Un troisième point de repère anatomique est identifié pour déterminer une deuxième relation spatiale par rapport à la première relation spatiale. Le profil du composant prothétique est positionné dans tous les degrés de liberté sauf un. Un quatrième point de repère anatomique est identifié pour positionner le profil du composant prothétique dans le degré de liberté restant.
