[Technique and results of arthrodesis of the ankle joint with autocompression plates (author's transl)].

The article describes the technique of arthrodesis of the ankle joint, introduced in 1973 by Mittelmeier, with suitable preparation (freshening) of the joint, resection of syndesmoses and internal osteosynthesis with autocompression angle plates, as well as additional fastening by screwing the fibula against tibia and talus. This method imparts high biomechanical stability to the joint thanks to the internal bracing of the frame; compared with external fixation, this method offers the advantage of avoiding the risk of subsequent infection of the borehole, as well as the possibility of early impaired wearing of trousers and of being able to bathe after superficial wound healing. Treatment results achieved in 14 patients showed (despite 1 reinfection following osteomyelitis caused by a fracture due to a bullet wound) regular, rapid and stable osseous reconstruction of the joint in which arthrodesis had been performed. Hence, this technique seems to be superior to external compression arthrodesis in aseptical cases.
