Optimization of Drill Geometry for Orthopaedic Surgery

Summary

With the advent of internal fixation a surgeon can assist the natural process of bone repair by ensuring that a perfect reapposition of parts is achieved. The rigidity of internal fixation determines the success of open fracture treatment, which most commonly depends on the correct use of plates and screws. This paper outlines the present state of knowledge on the performance testing of orthopaedic drills. It surveys the results of an experimental programme to minimize the forces developed in the drilling of bone, and to ensure accurate location of the holes produced, in order that maximum control of the drilling process can be maintained by the surgeon.
