[Biomechanical investigations of osteosynthesis at metaphys area of tibia and femur with selftensed angle plates (author's transl)].
Straight pressure plates create an eccentric tension force as well as an osteosynthesis with angle pressure plates. Both kinds of plate incline to gape the osteosynthesis and/or fracture gap. Therefore an overbending or additional angle allowance is necessary. In our biomechanical investigations we showed that at average bone stability, an overbending of the angle respectively an additional angle allowance of 3 degrees is most favourable. Uniform distribution of power transmission can be achieved at the entire osteotomie level using large and small angle plates with appropriate plate thickness and plate tension force. Sufficient stability in mobilisation is guaranteed without additional cast fixation.
