Abstract:
An osteosynthesis system for the spinal column, the system comprising at least two anchor members (2) adapted to be fixed to two vertebrae (4) of the spinal column, and a link member (6; 106) adapted to interconnect the two anchor members in translation towards each other, the link member (6; 106) being elastically deformable in bending about at least one deformation axis (45, 47, 49), the link member (6; 106) having at least two fixing portions (16) adapted to be fixed to the two anchor members (2), and at least one intermediate portion, the intermediate portion being offset from an alignment axis defined by the two fixing portions (16), wherein for at least one intermediate portion the link member (6; 106) further has two abutments (39) facing each other and disposed so as to come into abutment against each other when the link member is deformed about at least one deformation axis, in a given direction of rotation and through an angle (a) equal to a predetermined limit value.
