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.

Abstract: Spinal implant trials are provided having various configurations and sizes that aid the selection of spinal implants having similar configurations and sizes. A surgeon during surgery can insert various configurations and sizes of the spinal implant trials into a disc space between two adjacent vertebral bodies of a patient to enable the selection of a spinal implant configured and sized to fit the patient's disc space. Fluoroscopic images can be used in aiding the selection of an appropriately configured and sized spinal implant corresponding to one of the spinal implant trials. The spinal implant trials include features that reveal on the fluoroscopic images whether the spinal implant trials are properly located and oriented in the disc space and include features corresponding to different sizes of spinal implants also revealed on the fluoroscopic images.

Abstract: A spinal implant comprises an implant body extending between an anterior surface and a posterior surface, and including a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least one opening oriented to implant a fastener oblique relative to a lateral axis of a subject body and adjacent an intervertebral space of the subject body. The implant body defining a cavity such that a surgical instrument is connectable with the implant body adjacent the cavity and movable relative to the implant body. Systems, surgical instruments and methods are disclosed.

Abstract: A pivoting wedge expandable spinal implant. An upper portion and a lower portion are pivotally connected together. The implant, in a collapsed position, is inserted into a disc space. A driving screw engages and applies a force to a pushing portion, driving the pushing portion toward the implant's distal end. The pushing portion engages and drives a wedge toward the implant's distal end. The wedge pivots upward against an inner surface of the lower portion. The wedge continues to pivot along an inner surface of the upper portion, translating the force to the upper portion, pivoting and expanding the upper portion to an expanded position.

Abstract: Disclosed is a method and system for performing a procedure. The system may include a navigation system to be used to at least assist in the procedure. The system may assist in delineating objects and/or determining physical characteristics of subject portions. The system may assist in performing and/or a workflow of the procedure.

Abstract: A spinal implant comprises a body including a first vertebral engaging surface and a second vertebral engaging surface. The first vertebral engaging surface is rotatable relative to the second vertebral engaging surface. Systems and methods are disclosed.

Abstract: A surgical instrument includes a first member having an inner surface and an outer surface. A second member has an inner surface and an outer surface. At least one of the inner surfaces defines at least one mating element and the outer surfaces are engageable with tissue. The members are relatively movable between a first configuration and a second configuration to space the tissue and define an opening between the members. At least one third member defines at least one mating element engageable with the at least one mating element of the inner surface such that the at least one third member is disposed within the opening. Systems and methods are disclosed.

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.

The spinal implant trials include features that reveal on the fluoroscopic images whether the spinal implant trials are properly oriented and positioned in the disc space. As such, the selection of the configuration and size of the spinal implants can be made after it is determined that the spinal implant trials are properly oriented and positioned within the disc space.

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: An interbody implant system is provided. The interbody implant system includes an implant having an engagement surface and an instrument including a first member and a second member that is movable relative to the first member. The first member is configured to capture the implant and the second member includes an interface configured to engage the engagement surface to releasably lock the implant in at least one orientation relative to the second member. The at least one of the engagement surface and the interface include at least one planar face. Methods of use are disclosed.

Abstract: A surgical instrument comprises a member connected with a spinal implant defining an axis. A first image guide is connected with the member and oriented relative to a sensor to communicate a signal representative of a position of the member. A second image guide is connected with the member and oriented to represent an angle measuring a second orientation of the axis relative to a first orientation. Systems, implants 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.
