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.

The invention concerns an equipment comprising two shoring rods, members for anchoring said two rods to the vertebrae, at least a crosspiece (1) in two parts (5, 6) and members (2) assembling said crosspiece (1) to the shoring rods. The invention is characterised in that one of the crosspiece parts (5) comprises a spherical head (7) and a thread (8) adjacent to said head (7); the other crosspiece part (6) comprises a spherical bulging end (9), defining internally a spherical cavity (10) adapted to receive said head (7), and each crosspiece (1) comprises a nut (12) designed to co-operate with said thread (8), including further a spherical seat (13) with a shape matching that of the wall (11) delimiting the cavity (10). The invention also concerns plates (30for anchoring the equipment to the sacrum.

The equipment includes at least one connecting bar, at least one flexible ligament, and at least one connector making it possible to connect the ligament to the connecting bar. The connector having a first conduit for engaging the connecting bar, equipped with a device for immobilizing the connector relative to the connecting bar, and a second conduit for receiving at least one strand of the ligament, having an insertion opening for this or these strands and an outlet opening for this or these strands, and equipped with devices for mobilizing the ligament relative to the connector. The second conduit is rectilinear between the insertion opening of the strand(s) of the ligament and the outlet opening. The second conduit has a transverse section adjusted to the transverse section of the strand(s) of the ligament that it is intended to receive, i.e. a transverse section just sufficient to allow sliding of the strand(s) of the ligament in the second conduit, but such that the strand(s) are in close contact with the walls delimiting the second conduit.

This equipment comprises at least one anchoring assembly including two antagonistic hooks connected to each other through a rod, a first of these hooks having a body crossed by a hole for letting through the rod and being able to be connected to connection means with which the anchoring assembly may be connected to another part of the equipment; said body has an aperture laid out substantially perpendicularly to the axis of said hole, communicating with this hole, and the anchoring assembly comprises has a tightening member which may be engaged into this aperture until it abuts against the rod engaged in the hole, and tightened in order to immobilize this rod in this hole. Said tightening member is directly connected to a part belonging to said connection means, which allows the mounting of the latter on the body of said first hook.

摘要:
A method for rotating a vertebra or vertebrae in a spine that is curved using a vertebral osteosynthesis device that includes polyaxial screws, linking rods, clamping parts, tightening nuts, and set screws. The method includes the steps of: implanting two series of the screws, clamping parts, and linking rods; completely tightening the tightening nuts of a first series of screws on the convex side of the spine curvature; completely tightening the set screws of a second series of screws on the concave side of the spine curvature; tightening the tightening nuts of the second series; and tightening the set screws of the first series.
