Abstract: An intervertebral implant includes a body having a first face, a second face connected to and opposite the first face, a width and a length at least as long as the width that extend around the first and second faces, and first and second connection portions for connecting the implant to a separate holding member. The first and second connection portions each includes a hollow space accessible from outside the body through an opening formed between the first and second faces. The openings are elongate and extend away from one another around the implant from a same first side that defines the length of the body to respective second and third sides opposite to one another that define the width of the body, and are arranged such that the first and second connection portions are simultaneously engageable by the holding member.
