A new shape editing method for the design of fracture fixation plates based on stress analysis

The mechanical environment of fractured bone after plate implanting is one of the important indicators to evaluate the plate design. In this paper, a novel method of plate editing based on stress analysis was proposed. With CT scans, the finite element analysis model of fracture plate and individual femur was constructed, then the characteristic shape of the plate was modified to improve the mechanical distribution of the plate by parametric feature shape editing. Experiments show that the proposed method has the advantages of simple and efficient, clear operation semantics.
