Diabetes Mellitus is a non-communicable chronic disease of multifactorial origin, whose prevalence in Chile is 12.3% in the population over 15 years of age. Among the consequences of this disease there is the diabetic foot, whose main treatment is the partial amputation of the foot. In this context, the objective of the research is to design a partial foot prosthesis for the transmetatarsal and Chopart levels of amputation. The used methodology included the establishment of the patient’s profile, the definition of the design specifications and the subsequent proposal of the conceptual design. Then the detailed design was approached, carrying out the calculations of the forces to which the prosthesis is subjected, the material selection and the stress analysis using the finite element method to establish the final material and dimensions of the prosthesis. The designed prosthesis is composed of a polyurethane-thermoplastic or polypropylene material insole, and an aesthetic silicone cover; It includes both levels of partial foot amputation in the same template, does not restrict the degrees of freedom of the ankle, and is personalized for the patient, which is relevant when working with patients with diabetes.
