ABSTRACT:
To be able to secure a bone screw, in particular one that can be aligned polyaxially, especially fixedly and nevertheless easily and detachably in an osteosynthesis plate or a comparable implant, a clamping bore is proposed in addition to a receiving bore, whereby the receiving bore holds a bone screw directly or indirectly, and the clamping bore runs essentially perpendicular to the osteosynthesis plate or parallel to the receiving bore, and with a recess in the area of the bores, preferably between the bores, being arranged in relation to the receiving bore in such a way that widening of the clamping bore results in a constriction of the receiving bore.
