A line of joint implant systems includes an implant including a cup to be affixed in one of the elements of the considered joint, defining a smooth inner cavity of substantially hemispherical shape. The implant also includes an insert, mobile within the inner cavity of the fixation cup and having its smooth outer surface intended to cooperate by ball-and-socket joint with the inner cavity, and defining in turn a smooth inner cavity of substantially hemispherical shape. The implant further includes a head or ball, solid with a second element of the joint, of spherical shape, intended to be received in the inner cavity of the mobile insert and to form a second ball-and-socket joint. The ratio of the inner diameter of the inner cavity of the fixation cup to the inner diameter of the inner cavity of the mobile insert is constant, whatever the diameter of the selected ball.

The invention relates to a system which is used to replace ball bone joints. The inventive system consists of: a bone anchoring shell () comprising a smooth articular surface () on the inner concave face thereof; a prosthesis () comprising a polished ball () and a neck () which is characterised in that it is smooth and slightly flared, in order to enable a wear-free low friction movement; and a mobile articular cup () which slides (i) on the ball () and the neck () of a prosthesis () and (ii) in the smooth cavity () of the bone anchoring shell () and which is characterised in that the opening () in said cup () tapers towards the center thereof, with an inside diameter () of equal to or less than that of the ball (), such that the flared part adapts perfectly to the flared neck () in all of the respective positions of the mobile parts.
