Abstract

An implant is provided for fixing neighboring bone plates of the cranial bone in a simple and reliable manner. The implant comprises an outer bearing element for covering a spacing gap between the bone plates, which sits on outer surfaces of the bone plates. The outer bearing element has a first pair of outer openings and a first pair of inner openings. An inner bearing element is provided for covering the spacing gap between the bone plates, which sits on inner surfaces of the bone plates. The inner bearing element has a second pair of outer openings and a second pair of inner openings. A thread-like tensioning element is provided which is threaded through the openings of the outer and inner bearing elements in a displaceable manner, such that, when tensioned, the tensioning element draws the inner bearing element and the outer bearing element together.
