[Dislocation fractures of the Chopart and Lisfranc joint].

Dislocation fractures of Chopart's and Lisfranc's (mediotarsal) articulation result from the effects of impact and, because there are many possible complications, require a high level of experience on the part of the treating traumatologist. To avoid residual joint incongruities and intra-articular osteochondral fragments with subsequent early arthrosis and the corresponding complaints, the indications for open reduction and functionally stable osteosynthesis should be broad. The osteosynthesis can be achieved by transfixation with adjustable screws and 3.5 or 2.7 mm screws suitable for small fragments. This permits postoperative treatment to be carried out with a walking cast rather than a full plaster cast. In emergency patients with multiple injuries, dislocation fractures in the tarsal region require immediate and definitive treatment in order to avoid grave consequences and pain severe enough to influence the quality of life.
