[Dynamic locking screw 5.0--first clinical experience]

The principle of "biological" plate osteosynthesis describes the optimum interaction between mechanics and biology with the aim to achieve an uneventful consolidation of the fracture by secondary bone healing. The preservation of soft tissue and blood supply are central points in this context. Empirical values show that a too rigid internal fixation can suppress callus formation. The dynamic locking screw - DLS - allows for a decrease of the rigidity of a plate osteosynthesis. The fracture motion is positively affected. The advantages of the angular stability are not affected. In the Trauma Centre Tuebingen 35 patients were treated with the DLS5.0 in the time between November 2011 and October 2012. These first clinical cases with the use of the large fragment DLS showed good results. Handling the DLS5.0 is comparable to the conventional locking screw - LS5.0. Complications were not caused by the DLS and their application.
