ABSTRACT:
A vertebral osteosynthesis device includes at least two bone anchoring elements (1) in the vertebral bone structures respectively (S, L5.), a longitudinal linking member (2) between the bone anchoring elements, and connector links (3) between the bone anchoring elements and said linking members. Each bone anchoring element includes a bond fixing part (4), a head (5) to be gripped by a screwing device, a threaded shaft (7) extending the grip head, and a clamping element (8) to be screwed on said shaft to lock together the connector link, the longitudinal linking member and the corresponding bone anchoring element; the threaded shaft (7) is provided at its end with a hinge ball joint (11) in a housing (12) of the grip head (5), enabling a multidirectional adjustment of the shaft (7) and a positioning of the connector link (3) adapted to the vertebral segment configuration (S, L5, . . . Lw) receiving the bone anchoring elements.
