A modular articulated spacer system provides for screw-based assembly of an articular spacer intended to replace an artificial joint temporarily, whereby the articulated spacer system comprises at least two modules connectable by means of a screw connection, whereby a first module of the articular spacer system comprises a surface for formation of a sliding surface of the joint of the articular spacer and a second module of the articular spacer system comprises a stem for connection to a bone. The modules are connectable by means of the screw connection comprising at last one screw-locking device for each screw connection, whereby the screw-locking device is connected to one of the modules or is provided in the form of the same part as one of the modules. A method builds-up an articular spacer using said articulated spacer system, in which the articular spacer is screwed together using at least two modules, whereby the modules are screwed together appropriately such that the screw-locking devices prevent the modules from detaching or being unscrewed. |
