Title
(EN) SURGICAL DEVICE FOR IMPLANTING A RESURFACING PROSTHESIS
(FR) DISPOSITIF CHIRURGICAL D'IMPLANTATION D'UNE PROTHÈSE DE RESURFAÇAGE
Abstract
(EN)
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.

En vue d' implanter une prothèse de resurfaçage pour une articulation entre un os long (F) et un autre os (B), ce dispositif (1) comporte: - des premiers moyens de mesure (2, 3) adaptés pour mesurer, par rapport à un axe de référence (X-X) associé fixement à l'os long (F), et mémoriser de manière per-opératoire la position de points anatomiques (F4) du col anatomique (F2) de cet os long, -des seconds moyens de mesure (2, 3) adaptés pour mesurer, par rapport à l'autre os, et mémoriser de manière per-opératoire plusieurs positions de l'axe de référence, correspondant en particulier à des configurations articulaires extrêmes de l'articulation, propres au patient opéré, et -des moyens de comparaison (2) adaptés pour comparer, de manière per-opératoire, la position relative entre, d'une part, au moins un des points anatomiques du col anatomique de l'os long pourvu virtuellement de la tête prothétique (11) de la prothèse de resurf açage et, d'autre part, la bordure d'une cavité (16) qui est liée fixement à l'autre os et dans laquelle la tête prothétique est prévue de s'articuler de manière sensiblement complémentaire, et ce au moins dans chacune desdites plusieurs positions de l'axe de référence. En utilisant ce dispositif, le chirurgien peut déterminer facilement et rapidement, au cours de l'intervention chirurgicale proprement dite,- une configuration préférentielle pour implanter la tête prothétique, afin de réduire les risques de luxation ultérieure de la prothèse implantée.
