Abstract: A spinal fusion implant includes a leading end, an opposite trailing end, an upper portion extending between the leading and trailing ends, a lower portion extending between the leading and trailing ends, and opposed first and second side portions extending between the leading and trailing ends. The upper portion includes at least two rails extending between the leading and trailing ends, the at least two rails including a first rail and a second rail spaced apart from one another, the first rail of the upper portion including a bone-contacting surface being at least partially smoothened. The lower portion includes at least two rails extending between the leading and trailing ends, the at least two rails including a first rail and a second rail spaced apart from one another, the first rail of the lower portion including a bone-contacting surface being at least partially smoothened.

Abstract: An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.

Abstract: A spinal implant includes a body having opposite first and second end walls and opposite first and second side walls. The side walls each extend from the first end wall to the second end wall. A first cap is coupled to top ends of the walls. A second cap is coupled to bottom ends of the walls. The implant includes an opening extending through the caps such that the first cap defines a first ledge extending from the walls to the opening and the second cap defines a second ledge extending from the walls to the opening. Systems and methods of use are disclosed.

Abstract: A surgical implant includes a body portion, a first tier, and a second tier. The first tier is attached to an upper surface of the body portion, and the second tier is attached to a lower surface of the body portion. Each of the upper surface and the lower surface of the body portion includes channels formed therein. The first tier includes a first layer including a plurality of first slats and a second layer including a plurality of second slats, where the plurality of first slats and the plurality of second slats intersect one another to form openings therebetween. The second tier includes a third layer including a plurality of third slats and a fourth layer including a plurality of fourth slats, where the plurality of third slats and the plurality of fourth slats intersect one another to form openings therebetween. When the first tier and the second tier are attached to the body portion, a passageway is formed through the openings formed in the first tier to the channels in the upper surface of the body portion, and a passageway is formed through the openings formed in the second tier to the channels in the lower surface of the body portion.

Abstract: A spinal implant includes an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body defines a cavity. A plate is connectable with the implant body via a coupling member adjacent the cavity and is translatable relative thereto. The coupling member has a portion including a frangible torque limit. The plate defines at least one opening oriented to implant a fastener with tissue. Systems, spinal constructs, surgical instruments and methods are disclosed.

Abstract: A spinal implant for insertion into a disc space between an upper vertebral body and a lower vertebral body is provided. The spinal implant includes an upper first end plate portion and a lower second end plate portion each extending from at least adjacent a proximal end to a distal end of the spinal implant. The spinal implant is configured to facilitate insertion into the disc space and inhibit withdrawal from the disc space. To the end, the leading end of the spinal implant can be configured to facilitate ease of insertion into the disc space, and an upper surface and a lower surface of the upper first end plant portion and the lower second end plate portion, respectively, can be provided with depressions or dimples forming ridges and points therebetween to inhibit withdrawal from the disc space.

Abstract: A fixation element for use in orthopedic surgery, particularly spinal surgery is disclosed. The fixation element is capable of being screwed, hooked, or otherwise attached to a bone, and is configured to accommodate two or more rods or other elongated members. The head of the fixation elements thus has multiple places for positioning a rod, either vertically or horizontally spaced from each other.
