Abstract: A synthetic ligament for knees, made of biocompatible material, including an active ligamentary part arranged between the femoral and tibial regions of intra-articular penetration. The active ligamentary part having a first pair of parallel main elements and a second pair of intermediate elements which are crossed and integral with the first pair of main elements at the region of intra-articular penetration of the knee joint.

Abstract: Prosthetic cupule comprising:a metallic support cupule (6),a friction cupule in plastic material (20), of which the external shape corresponds to the internal shape of the support cupule,characterized in that:the support cupule (6) is provided in its center with an opening (14);the external shape of the friction cupule (20) comprises respectively a first cylindrical portion (22), joining up with a truncated portion (23), which is itself joined with a flat portion (25) provided in its center with a cylindrical central lug (24);and in that the internal face (21) of the friction cupule (6) is semi-spherical.

Abstract: Total hip prosthesis with primary fixation is provided with three essential parts:a femoral pin, for insertion into the femur;a cotyloidal cupule, for engagement into the acetabulum of the treated hip; anda prosthetic neck, covered with a sphere which joins the pin to the cupule and is intended to make the articulation proper. The threaded femoral pin has a special tulip-shaped anatomical profile, with a progressively variable radius.
