Usually a normal high-speed drill is used for the resection of uncarthrotic and spondylophytic bone. In one patient, we used our new high-speed drill close to the dura in an area, which is not easy reachable with a normal drill or a rongeur.


Employing the new drill with a polished tip, the spine surgeon is able to overcome the anatomical restrictions, which he has to face when the anterior approach to the cervical spine. The resection of dorsal osteophytes is easy and safe.


The newly developed drill with the polished tip is a safe and high-quality alternative to conventional drills. Further investigations have to be done, to proof the advantages of the new drill.
