摘要:
A system for guiding an implant to an optimal placement within a patient includes a trajectory guide for guiding instruments along a selected trajectory and a trajectory fixation device for fixing the trajectory guide in a selected position. The trajectory guide defines a path configured to align with the selected trajectory. A movable support mounts the trajectory guide and selectively moves the trajectory guide to align the trajectory guide with the selected trajectory prior to fixing the trajectory guide in the selected position. The trajectory is aligned coarsely by hand, then the trajectory is aligned using a fine adjustment system. After fixing the trajectory guide, instruments can be inserted along the trajectory through the path defined by the trajectory guide.

A spinal implant including a stabilization member coupled to an elongate member is herein provided. The implant can be configured for placement within a facet joint in an intra-facet or trans-facet configuration. Also, the implant can include a fusion-promoting bioactive material thereby providing a single device capable of spinal stabilization and/or fusion. Furthermore, a method of placing such an implant within a facet joint in an intra-facet or trans-facet orientation is hereby provided.

Mechanical modifications to a spinal rod that will enable the rod to accept various coating technologies in such a way that the spinal construct's biomechanical performance is not compromised. These modifications preserve construct biomechanics in the presence of a coating and increase the bactericidal payload of an anti-infective spinal rod coating.

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.
