Abstract
An interbody spinal fusion implant includes a tapered body and a faceplate secured to the tapered body. The faceplate has a recess formed on a front face of the faceplate that is at least partially bounded by an interior surface. A first screw hole and a spaced apart first locking slot pass through the faceplate, the first locking slot having an elongated width. A first locking screw has a head and a threaded shaft, the threaded shaft passing through the first locking slot and being sized so that the threaded shaft can slide laterally along a length of the elongated width of the first locking slot. A first nut is disposed between the tapered body and the faceplate, the shaft of the first locking screw being threadedly engaged with the first nut.
