Abstract: An automated screw rod bender includes a sensing system for sensing a position of each of a plurality of screws that are inserted into a vertebrae, a computing system for converting the positions into a geometric coordinates of the screws and generating a corresponding plurality of rod bending parameters, and a rod bending system for bending a rod based on the rod bending parameters.

Abstract: A vertebral plating system includes a bone screw and a vertebral plate. The bone screw includes a screw head and a shaft. The screw head includes at least three segments flexibly attached to the shaft and has a spherical outside surface. The plate includes holes to receive the screw and that have a spherical inside surface. A driver tool has pins that are inserted into a pin hole on each segment, and that causes the segments to move towards each other when downward pressure is applied.

Abstract: Various materials, constructs, and methods for maintaining an intervertebral space are provided.

Abstract: A method of treating an aneurysm includes injecting a ferromagnetic material into the aneurysm and applying a magnetic field to the ferromagnetic material to form a ball in the aneurysm.

Abstract: A vertebral implant for replacing a biological disk includes a top and bottom plate. The implant further includes flexible coupling that couples together the plates while allowing the same degree of freedom in all axes of motion as the original biological disk.

Abstract: Various materials, constructs, and methods for maintaining an intervertebral space are provided.

Abstract: The present invention provides vertebral spacers having a lower surface and an upper surface, an anterior face and a posterior face extending from the lower surface, and at least one guiding groove for engaging an insertion tool. A system for delivering a vertebral spacer to the spinal column of a patient, includes an insertion tool, an optional guiding tool, a pusher, a vertebral spacer, and a cutting tool. The insertion tool accepts any of a pusher, a vertebral spacer, or a cutting tool and has at least one spacer guide for engaging with a guiding groove of a vertebral spacer. The vertebral spacer is inserted into a patient by inserting the insertion tool into an intervertebral space, engaging the guiding groove of a vertebral spacer with a space guide of the insertion tool, advancing a pusher into the insertion tool, thereby pushing the vertebral spacer into the intervertebral space and thereafter removing the pusher and the insertion tool.
