Method for producing a tailor-made implant

A method for producing a tailor-made implant intended to be implanted on a placement site of at least one damaged bone part, comprising the following steps:

• i. acquisition of one or more images of at least said damaged bone part;
• ii. graphical 3D representation of the image of at least said damaged bone part acquired at step i.;
• iii. superpositioning of a 3D representation of a standard implant on the 3D representation obtained at step ii., by positioning said standard implant on a placement site at the surface of said at least one damaged bone part, then, modification of the dimensions and/or adjustment of the shape of said standard implant, taking account of at least one parameter of said at least one damaged bone part, then modification of the outer surface of said standard implant, the modification of the outer surface of said standard implant being such that said standard implant thus positioned on said placement site is imparted an outer surface which is:
• 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, said functional surface being determined in such a way that, being at least partially in contact with a conjugate surface of the other bone part with which said damaged bone part cooperates, it ensures the articulation of said bone parts, the determination of said functional surface is performed while the two bone parts are in a functional position in the graphical 3D representation, an acquisition of one or more images of said two bone parts having been performed at step i;
• and
• iv. realization of the tailor-made implant from the definitive parameters of said implant obtained at step iii.
