The osteosynthesis system comprises two anchoring members (2) adapted for being fixed to two vertebrae (4), and a connecting member (6; 106) adapted for connecting the two anchoring members by exerting stresses preventing the two anchoring members from coming together in translation. The connecting member (6; 106) is capable of flexural elastic deformation about a deformation axis (45, 47, 49). It comprises two fixing portions (16) adapted for being fixed to the two anchoring members (2) and an intermediate portion (40). The intermediate portion is offset relative to an axis (18) aligning the two fixing portions (16). The connecting member (6; 106) comprises two stops (39) arranged so as to be urged in support when the connecting member is deformed about the axis.
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.
