The invention discloses a fracture healing
simulation method based on a
tissue oxygen environment and a mechanical environment. The method comprises the steps of establishing a three-dimensional geometric model of a fracture part, meshing the obtained geometric model to establish a finite
element model of a bone and a
callus, analyzing and solving the finite
element model to calculate a partial strain of a fracture area, establishing a vascular
growth model of the fracture area according to force stimulation, establishing each
cell proliferation and differentiation model of the fracture area,establishing an
oxygen transport model of the fracture area, calculating a new material attribute in a tissue, establishing a fracture healing iteration
simulation process of a force biological adjustment
algorithm, and judging whether the material attribute in the tissue reaches a material attribute value of the bone or not according to the calculated
tissue material attribute value, completing
simulation if so, otherwise updating the
tissue material attribute value and entering into next iteration simulation.
