Abstract

L'invention concerne un système d'implant composé d'un élément d'ancrage osseux et d'une tige de liaison, ce système étant destiné à la stabilisation dynamique d'articulations, en particulier de segments de la colonne vertébrale. Le système d'implant selon l'invention se caractérise en ce qu'il permet un mouvement relatif de translation entre l'élément d'ancrage osseux et la tige de liaison sans limitation, tout en empêchant dans une large mesure un mouvement relatif de l'angle entre ces éléments.
