<p>The inter-vertebral implant has two parts (2, 3), which may be uniportally implanted in a disc cavity (B) and connected to each other in it. The parts have an opening (4, 5) for housing spongiosa or bone replacement material. Both parts have a connector (23), which engage with each other on implantation in the disc cavity and thus connect both parts to each other. One part has a groove in which a spring of the other part may be introduced in a sliding manner. The groove and the spring are arranged on inner narrow faces of both parts which are to come together.</p> |
