The invention relates to a modular articulated spacer system 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 (1, 2) that can be connected by means of a screw connection (5, 6, 12), whereby a first module (1) 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 (2) of the articular spacer system comprises a stem for connection to a bone, in which the modules (1, 2) that can be connected by means of the screw connection (5, 6, 12) comprise at last one screw-locking device (8, 18) for each screw connection (5, 6, 12), whereby the at least one screw-locking device (8, 18) is connected to one of the modules (1, 2) or is provided in the form of the same part as one of the modules (1, 2). The invention also relates to a method for building-up an articular spacer using said articulated spacer system, in which the articular spacer is screwed together using at least two modules (1, 2), which are selected from a multitude of different modules (1, 2) to suit the anatomy and/or treatment situation, whereby the modules (1, 2) are screwed together appropriately such that the screw-locking devices (8, 18) prevent the modules (1, 2) from detaching or being unscrewed. And lastly, the invention relates to the use of an articular spacer made from said articulated spacer system as a temporary place-holder for an artificial joint. |
