A multi-level spine stabilization system is formed by providing a plurality of securing members, providing a plurality of rod segments configured to extend between the plurality of securing members, selecting a first rod segment from the plurality of rod segments based upon a first distance between a first vertebra and an adjacent second vertebra, selecting a second rod segment from the plurality of rod segments based upon a second distance between the second vertebra and an adjacent third vertebra, attaching a first, a second, and a third of the plurality of securing members to the first, the second, and the third vertebrae, respectively, forming a rod using the first and second rod segment, and attaching the rod to the first, the second, and the third securing members.

Modular multi-level spine stabilization system and method

A multi-level spine stabilization system comprises a plurality of securing members configured for attachment to a plurality of vertebrae. A plurality of adjustable rods segments extend between the plurality of securing members. The adjustable rod comprises a first rod segment that engages a second rod segment in an adjustable relationship. The length of the rod may be adjusted by moving the first rod segment relative to the second rod segment. For example, the first rod segment may be in a slideable relationship with the second rod segment such that sliding the first rod segment relative to the second rod segment results in a change in the length of the rod. In one embodiment, portions of both the first rod segment and the second rod segment are positioned within and secured to the securing member. Advantageously, the multi-level spine stabilization system described herein may be used to center dynamic portions of the rod between securing members.

Various exemplary instruments for introducing an implant using a posterolateral approach are also provided, as well as various exemplary methods for using such instruments. In general, the instruments are configured to interconnect to an implant and/or to a guide member such that the components are all docked relative to one another. This allows the various components of a multi-piece implant to be mated intraoperatively within the disc space, and in particular to be guided into alignment with one another.

Methods and instrumentation for disc replacement

Various methods and devices are provided for a facet replacement device. In one embodiment of the invention, a facet replacement device is provided and includes an elongate member matable to a first vertebra and a housing. The housing can have a connector formed thereon and matable to an adjacent second vertebra and an inner lumen formed therein. The housing can also include a deformable member disposed within the inner lumen and having an opening formed therein for slidably receiving at least a portion of the elongate member such that the elongate member can be angularly oriented relative to a longitudinal axis of the lumen.
