Abstract
A washer for use with a bone screw in the reduction and fixation of bone fragments includes a frusto-conical body having a leading end, a trailing end, an exterior surface and an interior surface. A central bore defined by the interior surface for insertion of a bone screw extends longitudinally through the washer. The interior surface is tapered resulting in the central bore's diameter being larger at the trailing end than at the leading end. The washer, when used in combination with a compression bone screw, improves seating of the bone screw head in the bone and results in enhanced compression.
