Placement apparatus and methods of use for implantation of spacers within an inter-vertebral disc space. In one embodiment, the load-bearing superstructure of the implant is subdivided and the bone forming material is positioned within an internal space of the placement instrument but external to the load bearing elements themselves. At least a portion of the bone graft material is freely contained within the disc space. A method of using the device is also described. In one embodiment, the placement device is used to place the implantable spacers at opposing ends of the disc space using a directly lateral surgical approach.
