  • Patent number: 8449581
    Abstract: A bone plate that may be used to maintain relative position of two pieces of fractured bone, for example, a fractured jaw bone. The bone plate has a slot and holes. The holes are surrounded by walls and the slot is also surrounded by walls. The thickness of walls surrounding the slot at their maximum is greater than the thickness of walls surrounding the holes. Often the nature of the fracture may require bending of the plate for implanting it as desired by the surgeon. Because walls of the slot are designed to be strong, the slot is not deformed when the plate is bent.
