Abstract

A bone plate system for osteosynthesis comprises a bone plate, a swivel screw, a clamping screw, a swivel hole formed in the bone plate as a through hole for receiving the swivel screw polyaxially, and a clamping hole, which is associated with the swivel hole and is formed in the bone plate as a further through hole for receiving the clamping screw. When the swivel screw and the clamping screw are screwed in, they are fixed with angular stability in multiple dimensions, as the screw heads of the swivel screw and of the clamping screw are secured by one another and by the bone plate against relative movement. The swivel screw and the clamping screw are each designed as a bone screw.
