摘要

A prosthetic foot is disclosed for improving the gait and comfort qualities of the amputee that participates in walking, running and jumping activities. An ankle pylon component attached to a foot keel of the foot allows hindfoot triplanar motion. An ankle joint and a subtalar joint provided in the hindfoot ankle pylon component permit closed kinetic chain motion of the foot. The ankle and subtalar joints are formed by respective struts of resilient material of a single piece of material of the ankle pylon component. The ankle pylon component can be used as a functional upgrade component to an existing low profile prosthetic foot, for example.
