RESUMO

Two models simulating fractures type C and B of the classification proposed by AO-ASIF Group (Arbeistsgemeinschaft fiir Osteosyntheseftagen - Association for the study of intemal fixation) were submited to eccentric compression taking in to account the femoralload axes. In the first experimental model (fracture type C) straight and wave plates with 14, 16 and 18 holes, fixing a 5Onm gap were tested comparatively. In the second experimental model (fracture type B), straight and wave plates with 14 holes, fixing a 2mm, with a deffect on the medial wall (opposed to the plate), were tested comparatively. Experimental Model I showed that bodies fixed with straight plates presented rigidity coeflicients significantly larger than the ones fixed with wave plates, and that there was reduction of the rigidity coeflicients in function of the increase of the distance between the fixation points of the plates to the sticks. Experimental Model II showed that the bodies fixed with wave plates presented coeflicients of rigidity significantly larger than the ones fixed with straight plates
