Claim 0:
1. A set of components for creating joint implant systems, the set of components including balls having a plurality of different diameters, a plurality of mobile inserts each corresponding to one of the balls, and a plurality of cups, each joint implant system comprising:
a cup configured to be affixed in an element of a considered joint, defining a first smooth inner cavity of substantially hemispherical shape, said first cavity having a first inner diameter;
a mobile insert within the inner cavity of the cup and having a smooth outer surface configured to cooperate by a first ball-and-socket joint with the first smooth inner cavity of the cup, and defining second smooth inner cavity of substantially hemispherical shape, said second cavity having a second inner diameter corresponding to one of the plurality of different diameters of the balls;
a ball of spherical shape having a respective diameter of the plurality of different diameters, said ball being solid with a second element of the considered joint, and being configured to be received in the second smooth inner cavity and to form a second ball-and-socket joint,
wherein a ratio of the first inner diameter of the first smooth inner cavity to the second inner diameter of the second smooth inner cavity for all of the joint implant systems achievable from the set of components, is constant, regardless of the respective diameter of the ball.
