Abstract

In an implant for fixing neighboring bone plates of the cranial bone comprising an inner bearing element which covers a spacing gap between the bone plates, an outer bearing element which covers the spacing gap and a connecting device which penetrates the spacing gap and which, when said bearing elements approach one another, connects the bearing elements together by means of a latching or a clamping connection in such a manner that they are no longer able to be moved apart, it is proposed that the two bearing elements be additionally connected by a thread-like tensioning element which is passed through the outer bearing element in displaceable manner and, when tensioned, moves the inner bearing element towards the outer bearing element in order to simplify the process of applying the implant and to ensure a secure connection of the bearing elements.
