Abstract: Equipment includes bony anchoring members, one or two linking rods, intended to be connected to these anchoring members, and parts for connecting the rod(s) to the anchoring members; at least one anchoring member includes a proximal stud articulated with respect to a base portion enabling bony anchoring; clamping elements enable assembly of the connecting part on the anchoring member. The proximal stud includes a surface forming an axial stop, against which the connecting part is intended to rest, and the clamping elements clamp this connecting part against this surface which is positioned so that the connecting part, when clamped there against, is not clamped against the base portion so that there remains, after clamping, a possibility of articulated backlash of the proximal stud with respect to the base portion.

Abstract: This plate (1) includes blocking elements (4b, 5, 6) including: at least one slot (5) comprising a first portion opening into the hole (2) and a second portion extending over a section of this hole (2), at a distance from the edge defining this hole (2), this slot (5) thereby isolating a portion of material (6); this portion (6) has a first part (6a) with a radially increased thickness and a second part (6b) having a radially reduced thickness; this part (6b) has a thickness such that the portion (6) may be radially mobile between a withdrawn position and an active position; a sliding nut (4b) engaged in the slot (5), able to be moved in such a way as to bring the portion of material (6) from its withdrawn position to its active position.

Abstract: Equipment includes bony anchoring members one or two linking rods to be connected to the anchoring members and be attached to the vertebrae by dint thereof, parts for connecting the linking rod(s) to the anchoring members, and clamping elements for locking the linking rod(s) in the connecting parts; at least one anchoring member includes one proximal stud articulated with respect to a body for gripping a vertebra. The proximal stud exhibits an articulation head in the form of a spherical cap; and the anchoring member body includes a cavity for accommodating the articulation head and a wall surrounding this cavity, this wall being crimped around the articulation head and shaped to provide a proximal form, at least partially hemispherical.

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.
