Abstract: A system for stabilizing a portion of the spine comprising an elongate plate attached to one or more vertebrae by a number of bone anchors, with the system including one or more features that provide visualization of an implant disposed within a vertebral space and/or the interface between the implant and the adjacent vertebral tissue. A holding instrument is included that is engageable to the plate for positioning the plate adjacent the spinal column.

Abstract: Instruments for inserting an implant in a space between adjacent bony portions include upper and lower guide members and a drive assembly between the spreaders with an implant positioned forwardly of the drive assembly. The drive assembly is coupled to a handle assembly, and the handle assembly is operable to move the implant forwardly between the guide members to position the implant in a space between the bony portions. The handle assembly includes a mounting portion to which the drive assembly is mounted and an actuating portion operable to effect linear movement of the drive assembly.

Abstract: A spinal interbody replacement device for supporting vertebrae in the space between the vertebrae includes a connecting member having upper and lower disc replacement members engageable thereto at opposite ends of the connecting member to provide a corpectomy device. The disc replacement members are sized to be positioned in a spinal disc space between adjacent vertebrae when disengaged from the connecting member.

Abstract: Retaining mechanisms are attachable to a bone plate to retain one or more bone engaging fasteners relative to the bone plate. The retaining mechanisms include a retaining element engaged to an attachment element. One or both of the retaining element and the attachment element are moveable relative to the plate to position and/or maintain the retaining element in contact with one or more bone engaging fasteners.
