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, and anterior aspect, and opposing lateral aspects, said implant comprising: a top surface to engage said first vertebral endplate when said implant is positioned within the interbody space, a bottom surface 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, said implant having a longitudinal axis and a length extending along said longitudinal axis 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, said length being dimensioned so as to extend between said lateral aspects of said interbody space when said implant is positioned within the interbody space and is at least two and a half times greater than said width, said width being greater than said height, said implant further including at least two 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 from the top surface to the bottom surface, said implant further including at least one keel structure extending along a portion of the length and on said top surface, said at least one keel structure extending parallel to said longitudinal axis.
