Abstract: A method for producing a tailor-made implant intended to be implanted at an implantation site of a damaged bone part, the method comprising a step in which a 3D representation of a standard implant is superposed on a 3D representation of a damaged bone part by positioning said standard implant on an implantation site of the damaged bone part, in order, if necessary, to modify the dimensions and/or to adjust the shape of said standard implant, and also, if necessary, to modify the outer surface of said standard implant, which may be either the impression or substantially the impression of the outer surface of said bone part in the state prior to superpositioning of said implant, when the geometry of the damaged bone part is intended to be retained, or a functional outer surface, when said tailor-made implant is intended to be used at the interface of two bone parts cooperating with each other.

Abstract: The invention relates to a guiding ancillary device designed to cooperate with at least two bone surfaces, and to the method for the production thereof. The invention also relates to a guiding ancillary device for use in orthopedic surgery, and to an assembly comprising a guiding ancillary device and at least one medical device.

Abstract: The invention relates to joint prosthesis elements, to a method of manufacturing prostheses, and to a kit for putting said prostheses into place. The prosthesis element which is put into place in a resection in the joint surface is defined by a contact surface C, a fixing surface F and, interconnecting said surfaces, a peripheral surface P which co-operates with a projecting rim R of the resection. An anchoring element A projects from the fixing face and penetrates into a corresponding anchoring hole D.
