Abstract
A bone impactor consists of a single piece of lightweight metal which has a handle and a smooth shank, across the tip of which extends a working surface that forms a symmetrical cylindrical concavity that may be fitted against an excrescence, followed by striking the butt end of the handle to compress the excrescence into the bone to relieve pressure on a nerve. The edges of the working surface are radiused to minimize cutting. That bone impactor preferably is one of a set of four, the working surface of the second impactor being rectangular and that of the third being circular, while the handle and shank of the fourth impactor have a uniform, rectangular cross section.
