An installation tool is provided for the efficient and effective placement of an implant between adjacent bone structures, preferably adjacent vertebral bodies, and for the subsequent removal of the device without displacement of the implant. The installation tool generally includes a pair of opposed levers, a pusher assembly disposed between the levers, and an installation tool removing element having a mass slidably disposed with respect to at least a portion of the pusher assembly. The levers are effective to separate adjacent bone structures, such as adjacent vertebrae, upon insertion of an implant. The pusher assembly is slidably movable with respect to the levers, and is effective to insert an implant between the adjacent bone structures. Once the implant is positioned between the adjacent vertebrae, the mass can be used to apply a proximally directed force to the opposed levers, thereby removing the instrument from the space between the adjacent bone structures.
