Abstract: The invention concerns a device comprising an implant (18) designed to be inserted at least partially between the vertebral bodies (4, 4?) of two neighboring vertebrae, said implant (18) being adapted to provide to said neighboring vertebral bodies (4, 4?) at least one degree of mutual freedom, said device further comprising at least an extra-discal member (20), arranged behind the intervertebral space (12), adapted to damp a movement between said vertebrae (2, 2?), at least in the intervertebral flexion direction.

Abstract: Stabilization systems for stabilizing one or more vertebral levels are provided. The systems include anchors engageable to the vertebrae and an elongate connecting member system that maintains distraction between the vertebrae while allowing at least limited vertebral motion of the stabilized vertebral levels. The stabilization systems can be employed alone in non-fusion procedure or in conjunction interbody fusion and/or postero-lateral fusion procedures. The connecting members are structured to maintain a constant or slightly variable distance between the anchors to which the connecting members are connected while the connections of the connecting members with the anchors allow motion.

The intermediate element (22) is received in an internal volume of the mobile element, (10), and the fixed element (2) is received at least partly in an internal volume (26) of the intermediate element (22). Means are provided for securing, at least in translation, said intermediate element (22) to the fixed element (2), comprising the periphery of the substantially rigid outlet of the internal volume of the intermediate element.

Abstract: The present invention is related to an intervertebral stabilizing device structured to connect two adjacent vertebrae. The device includes an upper stop element engageable with an upper vertebra and a lower stop element engageable with a lower vertebra. The stop elements include mutual support surfaces adapted to allow a mutual rotation of the upper and lower vertebrae about the patient's transverse and sagittal axes and to prevent a mutual rotation of the two vertebrae about a vertical axis. The support surfaces are further adapted to allow mutual translation of the vertebrae in a single direction along the sagittal axis and to allow translation between the two vertebrae in both directions along a vertical axis. Additionally, the support surfaces are also adapted to prevent translation between the two vertebrae in both directions along the transverse axis.
