Abstract: An intervertebral implant component of an intervertebral implant includes an outer surface for engaging an adjacent vertebra and an inner surface. A keel extends from the outer surface and is designed to be disposed in a slot provided in the adjacent vertebra. This keel extends in a plane which is non-perpendicular to the outer surface; and preferably there are two of the keels extending from the outer surface which are preferably offset laterally from one another. In another embodiment, an anterior shelf is provided at an anterior end of the outer surface, and this anterior shelf extends vertically away from the inner surface in order to help prevent bone growth from the adjacent vertebra towards the inner surface. Further in accordance with disclosed embodiments, various materials, shapes and forms of construction of the component and/or keel provide various benefits.

Abstract: A minimally invasive fixation system and method for providing access to a surgical site. The fixation system may include a holding assembly, the holding assembling preferably including a lateral implant holder which may be attached to a pedicle screw and a sleeve positioned in connection with the lateral implant holder to prevent the lateral implant holder from separating from the pedicle screw. The sleeve may further include a tissue protection portion to keep the tissue out of the surgical site. A holding sleeve may be operably connected to the holding assembly and pedicle screw and may be used to insert the pedicle screw into the body. Multiple constructs may be inserted into the body so that a portion of the holding assembly extends from the body and provides access to and visualization of the surgical site. A rod holder may also be used to insert a rod into the head of the screw. The rod may be held by the rod holder so that the rod may be angulated as the rod is inserted into the screw heads.

Abstract: A system for performing a less invasive surgical procedure and, in particular, devices and methods for spinal fixation. The system comprises dilation tool(s), at least one working/insertion cannula, a plurality of screws, at least one fixation rod for connecting the screws, and a rod inserter. The dilation tool(s) may be used to dilate an incision made in a patient to form an opening. Thereafter, a drill may be used to form holes in the vertebrae. An insertion cannula may be attached to a screw and inserted into the opening. The screws may be polyaxial screws and may be inserted into the vertebrae using a screwdriver. An operator may then move the insertion cannula to manipulate a head portions of the screws such that the head portions may be aligned to receive a fixation rod. A rod inserter may be used to insert a fixation rod into the head portions. After the fixation rod is in place, it may be locked to the screws, thereby fixing the system in place on the spine.
