Abstract: The present invention addresses rod rotation and slippage inside the tulip rod channel(s), as well as forcible rod bending as the spine and musculature bias towards a deformity, for example. The present invention provides a stabilization rod that, fundamentally, includes at least one flat surface on at least one side of the construct, this flat surface engaging a corresponding flat surface associated with the head body, set screw, or locking cap. Multiple flat surfaces may, of course, be used. The stabilization rod may also include one or more ridges and/or one or more keyed channels that is/are engaged by the head body, set screw, or locking cap.

Abstract: An interspinous fusion device for holding adjacent spinous processes of a spine of a patient in a fixed configuration, including: a first plate configured to engage one side of the adjacent spinous processes; a second plate configured to engage another side of the adjacent spinous processes opposite the one side of the adjacent spinous processes; and a spacer disposed between and coupling the first plate to the second plate, wherein the spacer allows one or more of the first plate and the second plate to pivot relative to the other plate in a first unlocked configuration and prevents one or more of the first plate and the second plate from pivoting relative to the other plate in a second locked configuration. Each of the first plate and the second plate includes a pair of opposed wing members protruding from a central bore.

In some embodiments, the distance between the blade holder and the removable blades may be adjusted.

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 assemblies 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.

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.
