Mathematical modeling of femoral diaphyseal fracture at an acute angle

Abstract

The aim of the work is to establish the regularity of the formation femoral diaphysis fracture under an impact action on the anterior surface of the femur at an acute angle. As a result of mathematical modeling, transverse and short oblique, comminuted fractures of the femoral diaphysis were studied. Application of mathematical modeling with final element analysis made it possible to visualize and predict the stresses arising in the trace-perceiving material under the impact action of a blunt solid object. The data obtained in modeling of the mechanism and morphology of the femoral diaphysis fracture are confirmed by the results of the original full-scale experiments. Absence of experiments and practical observations of femoral fractures with the above described conditions does not enable us to fully validate the mathematical model of femoral fracture and indicates the need for scientific research on biomannequins.
