Patent ID: 8425515

Claim:
A laminoplasty system comprising: a set of bone grafts, the bone grafts of the set each having a graft length, a plurality of the bone grafts of the set of bone grafts having differing graft lengths, a set of bone plates, a plurality of the bone plates of the set of bone plates including a first plate segment, a second plate segment, and a central plate segment interposed between the first plate segment and the second plate segment, the first plate segment including a first hole for receiving a bone anchor, the second plate segment including a second hole for receiving a bone anchor, the central plate segment including a graft opening for receiving an anchor to connect one of the bone grafts, the first hole spaced apart from the second hole by a plate length, at least some of the plurality of bone plates having differing plate lengths, and an instrument for connecting the bone grafts to one of the bone plates, the instrument including an instrument body having a plurality of spaced apart graft chambers, a first one of the graft chambers having a first end, a second end, and a chamber length extending between the first end and the second end, the instrument body including a first protrusion proximate the first end of the first graft chamber and a second protrusion proximate the second end of the first graft chamber, the first protrusion being sized to fit within the first hole of a first one of the bone plates, the second protrusion being sized to fit within the second hole of the first bone plate, the first protrusion spaced apart from the second protrusion a first protrusion distance corresponding to the plate length of the first bone plate.
