title: [Mechanical and technical aspects of an external fixator made of rings and Kirschner wires (using the Wittmoser and Ilizarov methods). Alternatives to plate osteosynthesis].
abstract: R. Wittmoser's closed method of compression osteosynthesis for treatment of diaphyseal fractures consisting of rings and transosseal wires described in the forties, which was perfected to a technique of plastic bone surgery by G. Ilisarov in the Sowjetunion is contrasted to the open technique of compression osteosynthesis with plates and screws (AO) favoured in the west. The advantages are described such as mechanical stability of the rings - in contradistinction to frame fixators - the use of external fixation system for ambulant patients as well as the possibility of temporary and local withdrawal and reimplantation of wires in contrast to the irreversible measures concomitant to the osteosynthesis by plates.
