摘要： Embodiments of the invention being disclosed are directed to a spine implant that allows for in situ adjustment or steering during implantation which allows for precise placement. The structure of the device is composed of a series of hinged link components connected by dowel or shear pins allowing for the links to rotate with respect to each other. The steering feature of the device is activated by a series of tension members connected or coupled to the links. As the tension members are placed in tension, typically by pulling the appropriate member, forces are placed on the individual links to actuate/rotate them in a clockwise or counterclockwise direction. By controlling the rotation of the links, the device may be steered in the desired direction.

摘要： A polyaxial screw body includes a side wall defining a lumen having a first end and a second end. An opening disposed at the first end of the lumen, includes an interior surface disposed in the side wall thereabout. The interior surface is adapted to accommodate a head portion of a pedicle screw. A transverse channel extends from a first aperture through the side wall to a second aperture and is adapted to accommodate a portion of a fixation rod therebetween. A lateral connector extending integrally from the side wall.

摘要： A stand-alone interbody fixation system having a cage, anterior fixation blade and posterior fixation blade. The cage includes an annular side wall with an open interior and upper and lower surfaces, the cage being configured to fit between end plates of adjacent vertebrae. The anterior fixation blade includes an anterior alignment boss with two opposing outward extending anterior blades with end plate penetrating tips configured to fit within the open interior of the cage. The posterior fixation blade includes a posterior alignment boss with two opposing outward extending posterior blades with end plate penetrating tips configured to fit within the open interior of the cage. The anterior alignment boss and posterior alignment boss being rotatably coupled to each other and with a first opening and a second opening in the annular side wall opposite the first opening. The anterior and posterior fixation blades are counter-rotating blades and the anterior alignment boss and posterior alignment boss are configured to receive or engage a blade activation tool having an anterior engagement portion and a posterior engagement portion configured to rotate the anterior and posterior fixation blades from a stowed position to a deployed condition.
