  • Publication number: 20080154307
    Abstract: There is disclosed a system and method for dynamic stabilization which provides for distraction of the inter-vertebral space while still allowing a patient a substantial range of motion. In one embodiment, an inter-vertebral dynamic brace is used to maintain proper distraction. The dynamic brace is designed to allow the vertebrae to which it is attached to move through their natural arc, maintaining the correct instantaneous center of rotation. An adjustable tensioning device is used to maintain the proper distraction and compression forces to restore and maintain proper kinematics, while allowing the dynamic brace to move through an arc centered with respect to the center of rotation of the portion of the spine between the vertebrae. In one embodiment, a method is provided for adjusting the dynamic brace both with respect to the center of rotation of the vertebrae in both the flexion/extension axis and in the superior/inferior axis.

  • Publication number: 20070225726
    Abstract: A method, apparatus, and system are provided to place an insert in a space between boney structures. The insert may be rotatably coupled to the delivery instrument. The delivery instrument may comprise a body and an articulating member. The articulating member may slidably interact with the insert to rotate the insert about a pivot point. A first actuator is operatively coupled to the articulating member such that actuating the first actuator translates the articulating member relative to the body. An engagement member may be coupled to the body and adapted to releasably and rotatably secure the insert to the delivery instrument. The articulating member and the engagement member may be offset from each other in such a manner that when the articulating member engages the insert, the insert rotates relative to the delivery instrument. Alternatively, the insert may be coupled to the delivery instrument via rotatable attachment members.

  • Publication number: 20070225810
    Abstract: A implant is provided for placement in a space between boney structures. The implant may comprise a flexible section. The flexible section may be either the anterior side or the posterior side of the implant or both, among other sides. The flexible section or sections may comprise one or more orifices, cavities, or low modulus of elasticity materials among others. The flexible section or sections may facilitate a wider range of motion than otherwise possible for a spinal column comprising a Lumbar Interbody Fusion (LIF) device. Additionally, the anterior side comprising a flexible section may have a different modulus of elasticity than the posterior side comprising a flexible section. The difference may facilitate a wider range of responses from the implant to movement generated forces in at least two directions.

  • Patent number: 7214227
    Abstract: A closure member, such as a set screw, and complementary receiving member are included in a medical implant device. The receiving member has a plurality of noncontiguous, threaded walls substantially defining a bore for receiving the threaded closure member. When the closure member is inserted into the receiving member, their respective threads interlock to join the noncontiguous walls of the receiving member. The closure member has an outer thread configured to interlock with the inner walls of the receiving member in a manner that aids in preventing the noncontiguous walls of the receiving member from moving away from the closure member. In certain embodiments, the closure member's outer thread includes a trailing edge having a point that is rearward of the trailing edge's root, and the outer thread includes a leading edge having a point that is forward of the leading edge's root.

  • Publication number: 20060173454
    Abstract: A method and system are described for immobilizing three or more vertebrae. The system includes a first bone anchor assembly, a second bone anchor assembly including a connector having a predefined arc, and at least a third bone anchor assembly. The first and second bone anchor assembly are inserted into the pedicles of vertebrae spanning at least a third vertebra. The third bone anchor assembly is positioned into the third vertebra between the first and second bone anchor assemblies using an arc defining instrument which is used to locate the proper position for the third bone anchor assembly based on the predefined arc of the connector. Once the third bone anchor assembly is in place the connector is rotated into position and captured by the first and third bone anchor assemblies.

  • Publication number: 20060106380
    Abstract: An extension for use in a procedure to implant a stabilization system for bony structures such as vertebrae is described. The extension is formed by a tubular body with an engagement mechanism at one end to removably engage with a poly-axial head of a bone anchor assembly. A locking ring working with a slide are used to temporarily lock the poly-axial head and extension in the desired relationship for performing the procedure. The locking ring includes a slot in which resides a pin on the slider. Twisting the locking ring causes the pin to move in the slot and thereby move the slider either up or down. In one position a locking body on the slider engages with the poly-axial assembly locking the extension in place. In the other position, the locking body is disengaged from the poly-axial head allowing the extension to be decoupled from the bone anchor assembly.

  • Publication number: 20060079894
    Abstract: A tool is described for use in a stabilization system for bony structures such as vertebrae, where the system involves connected a connector from one bone anchor in a vertebra to a second bone anchor in another vertebra. The tool includes a handle attached to an arm. The arm is connected by a pivot to a connector engagement mechanism, the pivot allowing the connector engagement mechanism to move from an orientation inline with the arm to an orientation at an angle relative to the arm by rotating at the pivot. The connector engagement mechanism is engaged to an end of the connector when the tool is in its inline orientation and by causing the movement, which can be by the movement of a lever on the handle, of the connector engagement mechanism to the angled orientation, the end of the connector is moved into a position for engagement with the second bone anchor.
