Abstract:
1. A spinal fusion implant positionable within an interbody space between a first vertebral endplate and a second vertebral endplate, said interbody space being at least partially defined by a posterior aspect, an anterior aspect, and opposing lateral aspects, the implant being positionable from a lateral approach to extend from one lateral aspect to the other, said implant comprising: a top surface including a plurality of ridges to engage said first vertebral endplate when said implant is positioned within the interbody space, a bottom surface including a plurality of ridges to engage said second vertebral endplate when said implant is positioned within the interbody space, a distal side, a proximal side, a first side wall defining an anterior side when said implant is positioned within the interbody space, and a second side wall defining a posterior side when said implant is positioned within the interbody space; wherein said implant has a length extending from said proximal side to said distal side, a width extending from said first side wall to said second side wall, and a height extending from said top surface to said bottom surface; wherein said implant has a length extending from said proximal side to said distal side, a width extending from said first side wall to said second side wall, and height extending from said top surface to said bottom surface; wherein said length is at least two and half times greater than said width; wherein said width is greater than said height; said implant further including first and second fusion apertures that each extend between the top and bottom surfaces and permit bone growth between the first vertebral endplate and the second vertebral endplate when said implant is positioned within the interbody space, said first and second fusion apertures being adjacent to one another and separated by a medial support extending parallel to said promixal and said distal sides and between said top and bottom surfaces; said implant further including at least three radiopaque markers situated between said top and bottom surfaces; wherein a first of the at least three radiopaque markers is disposed within said distal side of the implant, a second of the at least three radiopaque markers is disposed within said proximal side and a third of the at least three radiopaque markers is disposed within said medial support.
