[Internal compression arthrodesis of the ankle joint (with examination of stability for comparison]

A new technique of arthrodesis of the ankle joint by internal fixation with self-compression blade-plates is presented. The both possible techniques of inserting the plate lateraly or medialy are described. We prefer the lateral approach. After resection of the ankle joint we also resect the tibiofibular syndesmosis putting than in a transfixion screw. We than compare under biomechanical aspects the new techniques with Charnley's external fixation with compression clamps. The osteosynthesis with blade-plates gives a higher stability in which external splintage with plaster becomes unnecessary. Following our experiences consolidation occurs after 8 tp 12 weeks.
