Zusammenfassung:A system comprises a bone plate and a bone screw. The bone plate is provided with a through-hole, which extends from an upper face to a bone-side lower face of the bone plate. A lip is formed in the through-hole, which lip protrudes from the curved surface of the through-hole and extends in the circumferential direction of the through-hole. The bone screw has a head thread, which is designed to reshape the lip in the through-hole in order to form a threaded connection. The lip has a step arranged between the curved surface of the through-hole and a central region of the lip, which step extends along the lip. The system has the advantage that a bone screw can easily cut into the lip.
