摘要:
Orthopedic implants are disclosed that may be used in spinal applications. In one embodiment, a plate portion is provided with a threaded protrusion on which a connector for attachment to an orthopedic rod can be fitted. The protrusion may be multi-axially orientable with respect to said plate portion. The plate portion may include a dome having an inner surface that may be of conical shape, through which a portion of the protrusion may extend. A pin may be provided to retain the protrusion in place with respect to the dome. A second plate portion may be provided, which may be integral with or movable with respect to the first plate portion, that can be connected to a bone, e.g. iliac or sacral bone.

Anchoring plate for a device for osteosynthesis of the vertebral column, including means for connecting it to one or more rods or to a plate. Its lower face is configured to match the shape of a contact zone situated to straddle two vertebrae, and it has openings for the passage of screws. The device for osteosynthesis of the vertebral column includes one or more rods or plates connected to vertebrae by way of connectors and anchoring plates. At least one of the anchoring plates is of the above type described above.

The invention relates to an anterior osteosynthesis plate for lumbar-lumbar or lumbar-sacral vertebrae, the plate being of the type comprising: an elongate body: adapted to cover of the anterior portions of two consecutive vertebrae; possessing an anterior face (6) and an opposite posterior face (7); presenting end zones that are interconnected by a connection zone (11); and provided with two through holes for anchoring screws. According to this invention, the posterior face (7) of the plate presents a bearing surface (12, 13), which bearing surface is designed to come into contact with the anterior surface (3) of the corresponding vertebra, the bearing surfaces (12, 13)being firstly inclined to define an obtuse angle (&agr;) between them in the sagittal plane (S) matching the relative angle between the anterior portions of the two vertebrae, and secondly being interconnected in the connection zone by a concave extension (17) such that at least the posterior face (7) of the body presents a profile that is concave in the sadittal plane.

A connector (1) for a spinal osteosynthesis device, for connecting two rods to a plate fixed in a vertebra, includes a first orifice (2) opening onto two opposed faces (3, 4) of the connector (1), and two other orifices (5, 6) opening onto two other opposed faces (7, 8) of the connector (1). Each of the two other orifices (5, 6) are each designed to receive a rod (14, 15) of the osteosynthesis device. The connector (1) includes a mechanism making it possible, when the connector (1) is push-fitted onto a protrusion (100) of a bone anchor member, to tighten the rods (14, 15) simultaneously in the two other orifices (5, 6) when a nut (22) is screwed onto the protrusion (100). An assembly for spinal osteosynthesis device includes a plate (16) that includes a protrusion (100), a connector (1) as previously described, and a nut (22).
