  • Patent number: 8834531
    Abstract: A method of providing spinal stabilization is provided herein. More specifically, the method includes positioning a plurality of fixation assemblies within a plurality of vertebrae in a trans-lamina orientation wherein each fixation assembly includes a proximal portion configured to securely receive a stabilization element (e.g., a stabilization rod). The proximal portions of the various fixation assemblies can be aligned so as to secure at least one stabilization element in a desired position (e.g., along and above a midline of the patient's spine, adjacent and parallel to the midline). A system for providing spinal stabilization is also provided which utilizes trans-lamina delivery and positioning of fixation assemblies within target vertebrae thereby providing stronger fixation and a significant reduction in associated tissue damage.

  • Patent number: 8663287
    Abstract: Spine fixation constructs are configured to receive and retain a spinal rod onto a vertebral bone screw. The spine fixation constructs provide for 360° rotation about a bone screw and variable axial placement about the bone screw. In one form, a rod holder of the spine fixation construct is configured to be axially received onto the bone screw. Axial positioning of the rod holder on the bone screw is fixed through cooperation of the rod holder with a fixation component. The fixation component is axially received onto the bone screw. Retention of the spinal rod by the spinal rod holder is also provided via the fixation member. In one form, spinal rod retention is provided upon axial retention of the spinal rod holder onto the bone screw through cooperating action between the fixation mechanism and the spinal rod holder. According to an embodiment, a member of the rod holder is caused to pivot and capture the spinal rod upon receipt of the fixation member onto the bone screw and rod holder.

  • Patent number: 8641734
    Abstract: A Posterior Dynamic Stabilization (PDS) device that regulates physiologic spinal elongation and compression. Regulation of elongation and compression are critical requirements of Posterior Dynamic Stabilization devices. Elongation and compression of the device allow the pedicles to travel naturally as the spine flexes and extends. This interpedicular travel preserves a more natural center of rotation unlike some conventional PDS devices that simply allow bending. The device incorporates two components: 1) a spring that allows elongation/compression, and 2) a polymer core component that serves to increase the stiffness of the device in shear, bending, and tension, and also prevents soft tissue ingrowth.

  • Publication number: 20140031871
    Abstract: Anatomic points within the body are projected outside the body through the use of extenders (180, 182, 188). The projected points may then be used for measurement, or to facilitate the selection or configuration of an implant that is positioned proximate the anatomic points using a slotted cannula (143). Such an implant may be a rod (270) for a posterior spinal fusion system. Pedicle screws (140, 142, 148) may be implanted into pedicles of the spine, and may then serve as anchors for the extenders. The extenders (180, 182, 188) may have rod interfaces (214, 216, 218) that receive the rod (270) in a manner that mimics the geometry of the pedicle screws (140, 142, 148) so that the selected or configured contoured rod (270) will properly fit into engagement with the pedicle screws (140, 142, 148).
