    摘要: Various methods and devices are provided for navigating through bone. In one embodiment, a bone navigation device is provided and includes a bone penetrating member configured to be implanted in bone and having at least one optical waveguide extending therethrough. The optical waveguide is adapted to illuminate tissue surrounding the device and to receive reflected/transmitted light from the tissue to determine the optical characteristics of the tissue, thus facilitating navigation through the tissue. At least one window can be formed in the bone penetrating member for allowing light from the at least one optical waveguide to illuminate the tissue, and for receiving the reflected light.

    摘要: Various methods and devices for replacing damaged, injured, diseased, or otherwise unhealthy posterior elements, are provided. In one exemplary embodiment, a posterior implant is provided and can be adapted to control movement of two or more adjacent vertebrae. In particular, the implant can be adapted to control extension, flexion, and lateral bending of adjacent vertebrae. The implant can also be adapted to substantially prevent rotation of the adjacent vertebrae. In another exemplary embodiment, the implant can have an envelope of motion that is within an envelope of motion of a disc, either natural or artificial, that is disposed between adjacent vertebrae. In other words, the implant can be configured to allow flexion, extension, lateral bending of the vertebrae to within the amount of flexion, extension, and lateral bending allowed by the particular disc. The implant can also be adapted to substantially prevent rotation of the vertebrae relative to one another.
