Abstract

La présente invention concerne les systèmes pour ostéosynthèse. Le système selon l'invention se caractérise essentiellement par le fait qu'il comporte une vis pédiculaire 10 et une barre 50 d'axe longitudinal 51, la vis 10 comprenant une tête 11 en U avec deux branches 12, 13 et une base 14 pour définir un espace interbranches 15 dans lequel se loge la barre, une tige de vis 16 avec un filetage osseux Fio, et des moyens 20 pour bloquer la barre dans l'espace 15 comportant au moins une patte 21, des moyens de déplacement de la patte 21 par rapport aux branches 12, 13 dans un plan sensiblement parallèle à l'axe 51, ces moyens de déplacement étant agencés de façon que la patte prenne deux positions, une première position P1 dans laquelle la patte ne coopère pas avec la barre 50 et une seconde position P2 dans laquelle la patte coopère avec au moins l'une branches 12, 13 de façon qu'au moins une partie de la patte 21 soit située dans l'espace 15 et applique sur la barre 50 une force de pression orientée vers la base 14 du U. Application, notamment mais non exclusivement, à l'ostéosynthèse rachidienne.
