1. A method for promoting fusion across an intervertebral disc space, the method comprising the steps of:
accessing an intervertebral disc space via a lateral approach; inserting a first implant having a top surface, a bottom surface, a leading end wall, a trailing end wall, an anterior wall and a posterior wall; positioning said first implant such that the leading end wall rests on a distal lateral aspect of an inferior vertebral body adjacent the intervertebral disc space; inserting a second implant having a top surface, a bottom surface, a leading end wall, a trailing end wall, a flexible anterior wall and a rigid posterior wall, said leading end wall, trailing end wall, flexible anterior wall and rigid posterior wall defining a fusion aperture; positioning said second implant such that the leading end wall of the second implant runs along a length of and adjacent to the trailing end wall of the first implant; packing the fusion aperture of the second implant with bone growth enhancing material after the second implant is positioned within the intervertebral disc space; inserting a third implant having a top surface, a bottom surface, a leading end wall, a trailing end wall, an anterior wall and a posterior wall after the fusion aperture of the second implant has been packed with bone growth enhancing material; and positioning the third implant such that the leading end of the third implant runs along a length of and adjacent to the trailing end of the second implant, and the trailing end of the third implant rests on a proximal lateral aspect of the inferior vertebral body. |
