ABSTRACT:
Precontoured plating, screws, instruments and methods for osteosynthesis. Plates according to the present invention take advantage of the fact that human adult craniofacial structure and shape is highly similar among the population. The plates are thus preformed, pretempered, precontoured, and preconfigured during manufacture to fit a large proportion of the human adult population. The plates consequently require less time during surgery to twist and bend to conform to the skeletal structure and their crystalline and other structural characteristics need not be adversely affected by extensive bending, twisting and shaping in the operating room. The plates may be packaged and presented for use on forms which simulate portions of the skull so that their intended craniofacial location is easily recognized by members of the surgical team. Because bone thickness at particular craniofacial skeletal locations is highly consistent in the adult population, appropriate length screws may also be packaged with the plates with which they are to be used, as for instance, by insertion through the plates on the skeletal-shaped packaging form. The packaging also allows the plates to be presterilized to save time which would otherwise be used for sterilizing the plates. Screws, screw transport units and starters and dispensers for the plates and screws are also disclosed.
