Abstract:
1. An intervertebral implant comprising: an insertion end and an opposing engagement end; first and second opposed main surfaces configured to contact respective first and second vertebral endplates, each of the first and second main surfaces defining an anterior end, and a posterior end, and each of the first and second main surfaces disposed between the insertion and engagement ends; an anterior wall disposed between the first and second main surfaces, the anterior wall disposed along the anterior ends of the first and second main surfaces; a posterior wall disposed between the first and second main surfaces, the posterior wall disposed along the posterior ends of the first and second main surfaces, and the anterior wall and the posterior wall converging at the insertion and engagement ends; a slot defined at the engagement end, the slot continuously disposed between and at least partially along the anterior and posterior walls; a post positioned within the slot, the post spaced from at least one of the anterior or posterior walls, the post at least partially disposed between the first and second main surfaces, and the post defining a plurality of exposed facets, the plurality of exposed facets being configured to engage complementary facets of an insertion instrument so as to rotatably couple the post to the insertion instrument when the insertion instrument is engaged with the post; and an abutment surface disposed within the slot and spaced from the post, the abutment surface having a first portion and a second portion that is contiguous to the first portion, the first portion being angularly offset from the second portion, the first and second portions are configured to contact a surface of the insertion instrument when the post is engaged with the insertion instrument so as to prevent rotation of the intervertebral implant about the post.
