Abstract:
Objective To compare the biomechanical effect of three fixation instruments for SchatzkerⅥtibial plateau fractures.Methods Twenty four fresh knee specimens were made into models of SchatzkerⅥtibial plateau fractures.The specimens were divided randomly into three groups.Group A were fixed with a lateral periar- ticular plate and a posteromedial antiskid plate,and group B with a lateral periarticutar plate and an anteromedial lim- ited contact dynamic compression plate(LC-DCP),and group C with a lateral periarticular plate and a medical exter- nal fixator.Each model was tested for its biomechanical performance in resisting compression,bending and rotation. Results The performance of group B was higher than group A in anti-compression,anti-bending and anti-rotation, and group C was the poorest,there was no significant difference between group A and group B,and there was signifi- cant difference between group B and group C.Conclusion The biomechanical performance of group B was good. The method might have clinical applications in the treatment of SchatzkerⅥtibial plateau fractures.
