Screw for compression of bones, has head thread section with cutting thread, where external dimension and/or core dimension of thread and/or external dimension and/or core dimension of thread section is reduced with respect to screw thread

摘要

The screw (1) has a head thread section (2) with a cutting thread (3), and a distal thread section (4) removably arranged towards the thread section. External dimension and/or core dimension of the thread and/or external dimension and/or core dimension of the thread section is reduced with respect to a screw thread and/or another screw thread or conically towards a thread-less shaft section (18). A conical attachment tip (9) is formed at an end of the distal section, where the end lies opposite to the shaft section. An edge hole is formed at an end region of the thread section. Independent claims are also included for the following: (1) a device for inserting a bone screw into bones for compression of bones (2) a magazine for receiving a screw, comprising horizontal plates (3) a kit for implantation of a screw in bones, comprising a centering pin.
