  • Publication number: 20190110820
    Abstract: A vertebral fixing system having a flexible elongated member, a connecting part, and an anchor, where the anchor may engage a bone structure (e.g., a vertebra) through an opening of the connecting part and the flexible elongated member may connect to the connecting part. In some cases, the vertebral fixing system may include a tightening part configured to apply a tension to the elongated member and/or secure the elongated member with respect to the connecting part. The vertebral fixing system may be configured to receive a rod and may be capable of connecting thereto. The connecting part may have a plurality of connecting members, where at least one of the connecting members includes an opening for receiving the anchor and at least one of the connecting members connects to the elongated member.

  • Patent number: 9414937
    Abstract: A spinal implant for stabilizing first and second vertebrae. The spinal implant includes an intervertebral spacer and a bone stabilization member configured to be coupled to the intervertebral spacer. The bone stabilization member includes a plurality of bone screw openings and a plurality of bone screws extendable through the bone screw openings to secure the bone stabilization member to the vertebrae. A retention member, which is slidably coupled to the bone stabilization member, is linearly slidable between a first position and a second position while coupled to the bone stabilization member. In the first position, each of the bone screws is permitted to be inserted into the bone screw openings, and in the second position the retention member at least partially covers each of the bone screw openings to prevent a bone screw from backing out of the respective bone screw opening.

  • Patent number: 8900310
    Abstract: An intervertebral or spinal implant having a spacer, a cage, and a locking mechanism, where the locking mechanism may be configured to facilitate a connection between the spacer and the cage. In some cases, the spacer may include a distal end wall, a proximal end wall, a first lateral wall, and a second lateral wall, where the locking mechanism may be situated at the proximal end wall adjacent a receiving opening in the proximal end wall. The implant may have one or more spikes extending from a top and/or a bottom of the spacer to facilitate stabilizing the implant between vertebrae after insertion of the implant in the spinal column.

  • Patent number: 8740945
    Abstract: A spinal stabilization system including an insert positionable in the channel of the housing of a poly-axial pedicle screw which allows for locking the housing of the poly-axial pedicle screw from pivotal movement through a clamping force generated by rotational engagement of a fastener with the housing while clamping a cord of a support construct in the housing of the poly-axial pedicle screw through direct contact of the fastener against the cord.

  • Patent number: 8454700
    Abstract: An interbody vertebral implant for facilitating fusion of adjacent vertebrae. The implant includes a first end plate, a second end plate, and an intermediate member disposed therebetween. The end plates are configured to allow bone in-growth. The intermediate member may include features to engage the end plates and to prevent over insertion of the intermediate member within the end plates. The implant may include a cavity extending through the composite implant configured to receive bone growth material to facilitate fusion between a first vertebra and a second vertebra.
