Bone screw

Abstract

A bone screw is created, with a thread section ( 1 ) with a tip ( 6 ) at a first end and a head ( 8 ) for engaging with a screwdriver at the opposite second end, which serves as traction element to connect shattered or split off parts of bones to one another. So that fusion of the screw with the bones can take place, the thread section ( 1 ) is constructed as tubular and its wall has a plurality of recesses.
