  • Patent number: 11951011
    Abstract: 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.

  • Publication number: 20210275308
    Abstract: An acetabular implant for a hip prosthesis including: a fixation cup defining an inner cavity having a substantially hemispherical shape, made of polyethylene and having, on its outer wall, means capable of favoring its fixation with cement within the acetabular cavity of the pelvis of the patient to be prosthesized, the inner cavity being coated with an armoring made of a biocompatible material of high hardness, said armoring defining the smooth inner cavity of substantially hemispherical shape intended to receive the mobile insert; an insert, mobile within said inner cavity and having its smooth outer surface intended to cooperate by ball and socket joint with the inner cavity of the fixation cup, and defining in turn a smooth inner cavity also having a substantially hemispherical shape; said mobile insert being made of high-density polyethylene; a prosthetic femoral head or prosthetic ball, secured to a femoral stem, of spherical shape and intended to be received in the inner cavity of the mobile insert

  • Publication number: 20200390557
    Abstract: An anchoring stem for a joint prosthesis with a centromedullary fixation includes a metaphyseal-diaphyseal (M-D) portion intended to be inserted into the medullary canal of the long bone of the joint to be prosthesized. It receives an epiphyseal-diaphyseal (E-D) portion, having its upper portion protruding from the considered bone and intended to receive in turn an articular element. The M-D portion and the E-D portion are independent from each other but may be fastened to each other. The E-D portion is received within the M-D portion along a direction parallel or substantially parallel to the main dimension of the M-D portion, along a length of cooperation of the portions with each other such that the ratio of the length of reception of the E-D portion within the M-D portion to the total length of the M-D portion is in the range from 0.5 to 0.85.

  • Patent number: 7780737
    Abstract: The invention relates to a system which is used to replace ball bone joints. The inventive system consists of: a bone anchoring shell (1) comprising a smooth articular surface (7) on the inner concave face thereof; a prosthesis (5) comprising a polished ball (4) and a neck (6) 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 (3) which slides (i) on the ball (4) and the neck (6) of a prosthesis (5) and (ii) in the smooth cavity (7) of the bone anchoring shell (1) and which is characterised in that the opening (8) in said cup (3) tapers towards the center thereof, with an inside diameter (9) of equal to or less than that of the ball (4), such that the flared part adapts perfectly to the flared neck (6) in all of the respective positions of the mobile parts.
