ABSTRACT:
A medical implant has a secured bone screw which is guided through a bore of the implant. The bore has a thread matching the thread of the bone screw. Between the head of the bone screw and the thread thereon, there is an unthreaded portion whose diameter is not greater than the free inside diameter of the threaded bore. These threads prevent axial passage of the bone screw through the bore without turning. Turning is inhibited or excluded by an arrangement preventing turning.
