Development of a prototype for a prosthesis implant of one degree freedom for the ankle joint

Abstract

The loss of movement in the ankle joint is repeatedly linked to osteoarthritis, which is a disease that causes wear and tear on the cartilaginous tissue, preventing free movement between the tibia, fibula and astragalus. Currently one of the treatments to regain movement in the ankle joint is ankle arthrodesis, which is a surgical procedure during which flexo-extension mobility is restored to resume the high and low gait cycle Speed. To manufacture an artificial ankle joint it is necessary to establish the parameters that help control the manufacturing processes of each component, ensuring its proper operation. The mechanical design for this joint highly depends on the analysis of axial loads produced by the weight of the human body during the supporting phases and based on that information, select the appropriate materials that are useful not only to support the weight of the human body but maintaining an excellent level of biological compatibility.
