Abstract
A fusion implant for a facet joint comprises a bearing module and a fusion module, in which the fusion model is arranged on the bearing module and has a holder for a transfacetal fastener, whereby the bearing module includes an expansion element and jaw elements, which have contact surfaces for the lamina on their outer sides moving away from each other and which are arranged to move longitudinally on a guide, so that the distance of the fusion module is changeable using the expansion element. The bearing module forms a secure and safe anchoring for the fusion module, which can be repositioned. In addition, the bearing module has the effect of an augmentation, and as a result treatment is possible even on vertabrae that are weakened by defects.
