Abstract

Le système d'ostéosynthèse comporte deux organes d'ancrage (2) adaptés à être fixés à deux vertèbres (4), et un organe de liaison (6; 106) adapté à relier les deux organes d'ancrage en exerçant des contraintes à l'encontre du rapprochement des deux organes d'ancrage en translation. L'organe de liaison (6; 106) est déformable élastiquement en flexion autour d'un axe de déformation (45, 47, 49). Il comporte deux portions de fixation (16) adaptées à être fixées aux deux organes d'ancrage (2) et une portion intermédiaire (40). La portion intermédiaire est décalée par rapport à un axe d'alignement (18) des deux portions de fixation (16). L'organe de liaison (6; 106) comporte deux butées (39) disposées de façon à venir en appui lorsque l'organe de liaison est déformé autour de l'axe.
