Abstract: Methods, systems, and devices for replacement of a joint with a prosthetic system that replicates the natural kinematics of the joint is disclosed. A prosthetic system according to one embodiment includes a tibial component having a tibial plateau and a tibial stem portion, the tibial plateau having a top side and a bottom side, a tibial insert, with a bearing surface, adapted to be positioned on the top side of the tibial plateau, a femoral component having a base portion and a central housing, the femoral component having an axis of extension-flexion rotation, the base portion having a pair of condyles, an a mechanical linkage component linking the tibial component with the femoral component and with the tibial insert in between the tibial component and the femoral component, so that there is a center of contact between the condyles and the bearing surface.

Abstract: A hip prosthesis with interchangeable epiphysis. The prosthesis is formed from a neck and a head which form a one piece assembly, the neck having a reduced diameter at the level of the head and a greater diameter at its base. The assembly includes a housing for receiving a Morse cone which is integral with the upper pole of the femoral shank. Different sizes of the assembly may be used with different length shanks.

Abstract: A centro-medullary nailing rod for treating bone fractures, the rod being generally in the form of a longitudinally split tube, and being characterized by the fact that it includes locking tongues (3-4; 5-6) suitable for preventing or limiting relative displacement between the two edges (20-21) of the slot (2) in the longitudinal direction, while allowing relative displacement thereof in the transverse direction. The invention improves the resistant of the rod to twisting.

Abstract: The present invention relates to a cement which may be used for the fixation of osseous prostheses. This cement is obtained by hardening of a mixture comprising:(a) at least one epoxide resin having a high reactivity and a very low toxicity, consisting of a diepoxide of a glycidyl ether of bisphenol A;(b) a reactive, non-toxic suppling resin, consisting preferably of hydroxyl-terminated polybutadiene;(c) a mineral filler in powder form;(d) a hardener capable of reacting with said epoxide resin to effect hardening thereof, and(e) a hardening accelerator.The invention is more particularly applicable to the fixation of hip prostheses.

Abstract: A hip prosthesis comprising a thin metal cotyloid cup, substantially spherical in form, the dimensions of the outer surface of which are substantially equal to those of a the cotyloid cavity, and which is provided with a peripheral flange for abutting on the bone around the cotyloid cavity and for preventing the cup from pivoting; a thin femoral cup, also made of metal, extended by a skirt and substantially in the form of a finger guard; and a relatively thick intermediate cup made of plastics material, having a spherical outer surface adapted to pivot in the cotyloid cup, and an inner surface comprising a spherical central part extended by a cylindrical portion which fits on the femoral cup so as to allow said latter to move only in rotation about the axis of symmetry of the cups.
