Abstract

An osteosynthetic anchor bolt has a shaft which has at its front end an external thread having a major diameter greater than the diameter of the shaft and at the rear an internally threaded socket to accept a compression screw. The profile of the external thread is designed in such manner that there is maximum possible resistance to axial pressures acting on the anchor bolt frontally, laterally or both.
