  • Patent number: 8052726
    Abstract: A system and method for anchoring a connector to a bony portion of a spinal column is provided. The connector is engaged to the spinal column with an anchor. The connector receives an elongate connecting element that extends along two or more vertebrae of the spinal column. The connector includes an eyelet portion that houses a retaining member through which the anchor extends. The retaining member allows movement of the connector relative to the anchor prior to engagement of the connecting element to the connector. When the connecting element is engaged to the connector, the connector is fixed relative to the anchor and the retaining member.
    Type: Grant

  • Patent number: 8029545
    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.

  • Patent number: 6475218
    Abstract: A spinal implant for an osteosynthesis device having a bone anchorage portion, a connector portion adapted for connection to an elongate rod, an extension portion extending from the connector portion, and a threaded fastener operable to secure the implant to the elongate rod. The connector portion includes a pair of flanges extending axially from the anchorage portion and spaced apart to define a channel for receiving the elongate rod therein. The extension portion includes a first segment extending axially from one of the flanges and a second segment extending transversely from the first segment toward the other of the flanges so as to define a transverse opening capable of receiving the elongate rod therethrough. The fastener is advanced along a continuous thread extending between the extension portion and the opposing flanges to secure the elongate rod within the channel. In one embodiment, the extension portion is selectively separable from the connector portion.
