In order to implant a resurfacing prosthesis for an articulation between a long bone (F) and another bone (B), the device (1) comprises: first measuring means (2, 3) for measuring, relative to a reference axis (X-X) fixedly associated with the long bone (F), the position of anatomic points (F4) of the anatomic collar (F2) of said long bone and for preoperatively storing same; second measuring means (2, 3) for measuring, relative to the other bone, a plurality positions of the reference axis particularly corresponding to the end articulation configurations of the articulation particular to the operated patient, and for preoperatively storing same; and comparison means (2) for preoperatively comparing the relative position between at least one of the anatomic points of the anatomic collar of the long bone virtually provided with the prosthetic head (11) of the prosthetic surface, as well as the edge of a recess (16) rigidly secured to the other bone and in which the prosthetic head is provided so as to be articulated in a substantially complementary manner, and this in at least each of said several positions of the reference axis. When using said device, a surgeon can rapidly and easily determine a preferential configuration for implanting the prosthetic head during the surgical operation itself in order to reduce any risk of subsequently dislocating the implanted prosthesis. |
