Bone Plate System for Osteosynthesis

摘要

A bone plate system is for osteosynthesis with a bone plate, a bone screw, the screw head of which has, at least in sections, a surface structure, a further bone screw, the screw head of which has, at least in sections, a surface structure, a through-hole, which is configured to hold the bone screw polyaxially, a further through-hole, which is associated with the through-hole and configured to hold the further bone screw, a perforation which connects the through-hole and the further throughhole, and a bulge, which is formed opposite to the perforation on the through-hole, extending the latter, hi the screwed-in state, the bone screw and the further bone screw are affixed at a fixed angle in many dimensions by virtue of the screw heads of the bone screw and the further bone screw being secured against a relative notion in relation to one another and in relation to the bone plate by a tensioned multi-point mount, in which attachments of the bone screw are formed in the through-hole at both transition regions between the bulge and the through-hole section respectively adjacent to the bulge.

1. A bone plate system for osteosynthesis, comprising:
a bone screw, the screw head of which has, at least in sections, a surface structure, a further bone screw the screw, head of which has, at least in sections, a surface structure, and a bone plate, said bone plate having a through-hole, which is configured to hold the bone screw polyaxially, a further through-hole, which is associated with the through-hole and configured to hold the further bone screw, a perforation, which connects the through-hole and the further through-hole, and a bulge, which is formed opposite to the perforation on the through-hole, extending the latter, wherein in the screwed-in state, the hone screw and the further bone screw are affixed at a fixed angle in many dimensions in that the screw heads of the bone screw and of the further bone screw are secured against a relative motion in relation to one another and in relation to the bone plate by means of a tensioned multi-point mount in which attachments of the bone screw are formed in the through-hole at transition regions between the bulge, and the respective through-hole section adjacent to the bulge.
