15 of the plate 10 the first and second screws 40 are positioned respectively in the screw holes 11 and 12 of the plate 10 and thus anchor the plate 10 to the first bone 71 and the second bone 72 with the retention spacer 56 removed the shape memory plate 10 can now respond to room temperature body temperature or external energy input and transform in shape from its open shape 100 to its compressed shape 101 in particular the moveable arms 13 and 14 decrease in length resulting the first central opening 15 transitioning in shape to the second new central opening 18 while the moveable arms 13 and 14 transform the plate 10 in this preferred embodiment one of ordinary skill in the art will recognize that there are any number of designs orientations shapes and numbers of moveable arms that would create the same transformation effect upon the transitioning of the plate 10 to its compressed shape 101 compression is created between the first bone 71 and the second bone 72 at the bone fusion location 73 summarizing the implantation the surgeon selects a shape memory plate implant pre loaded onto an insertion tool the plate can also be pre loaded with drill guide tubes or those can be attached during surgery the surgeon positions the plate at the juncture of two bones to be fused or fixated and uses locating pins to temporarily hold the plate to the bones the surgeon then removes one locating pin and drill guide tube replaces it with a screw to hold one side of the plate in place.
