    摘要: Methods and devices are provided for spinal fixation. In one exemplary embodiment, the methods and devices provide one or more points of fixation located adjacent to a first fixation point at which a bone anchor is implanted in bone. For example, an extension member can be coupled, either directly or indirectly, to a bone anchor, and a fastener can be used to anchor the extension member to bone at a second point of fixation adjacent to the first point of fixation. The second point of fixation can be effective to prevent rotation or other movement of the bone anchor, thereby stabilizing the bone anchor. The methods and devices are particularly useful for unilateral fixation, in which one or more levels of the spine are stabilized along a single lateral side of the spine.

    摘要: An artificial disc replacement implant is provided that includes an implantable body having a superior surface adapted to be positioned adjacent to an endplate of a superior vertebra, and an opposite inferior surface adapted to be positioned adjacent to an endplate of an adjacent inferior vertebrae. The implantable body includes at least one wall formed therein and extending between the superior and inferior surfaces. The wall(s) can be adapted such that, when the implantable body is disposed between the endplates of adjacent superior and inferior vertebrae, the wall(s) will buckle by moving laterally and shorting in height under a load applied thereto by movement of the adjacent vertebrae. The implantable body can also include at least one opening formed adjacent to the wall(s) and extending between the superior and inferior surfaces of the implantable body.
