Abstract
A bone plating system includes a plate, fixed angle and variable angle bone screws, and corresponding set screws for each type of the bone screws. The plate includes common openings adapted to receive the variable and fixed angle bone screws, both of which can be locked relative to the plate with the set screws. In all modes of use, a set screw, sometimes in combination with a sliding washer, is then used to fix the level of compression and prevent loosening. In one mode of use, a bone screw can also be driven to cause displacement of the plate such that pressure is applied to maintain bone parts together about a fracture in tight engagement.
