Configuration of the Statics FEA for the prosthesis model. (A) Finite element mesh division of prosthesis model A. (B) Application of a 500 N force perpendicular to the horizontal plane on the upper surface of the Astragalus (Prosthesis A forms a 30° angle with the horizontal plane), with fixation points at the calcaneal tuberosity, sesamoid prosthesis and fifth metatarsal head. (C) Application of a 500 N force along the direction of prosthesis A on the upper surface of the astragalus (prosthesis A forms a 70° angle with the horizontal plane), with fixation points at the sesamoid prosthesis and the fifth metatarsal head.
