摘要： A transtibial prosthetic device comprises a pylon configured as a unitary truss structure formed of a plurality of elongated supports interconnected at nodes and having open spaces between supports of the plurality of elongated supports. The unitary truss structure comprises a polymer. A foot-ankle complex extends from a base of the pylon. The foot-ankle complex comprises an s-shaped posterior portion, an s-shaped anterior portion, and a sole portion. The s-shaped posterior portion and the s-shaped anterior portion both extend from the sole portion, have upper portions with curvatures that are concentric with each other, and are separated from each other by a gap.

摘要： A unibody transtibial prosthetic device includes a socket personalized for a specific patient's residual limb. A pylon extends from the socket, the pylon being a unitary polymer structure of interconnected elongated supports having open spaces therebetween. The device also includes a foot-ankle complex, the foot-ankle complex being a unitary polymer extending from the pylon, the foot and ankle unitary structure being shaped to provide multi-axial dynamic flex to enable dorsiflexion, plantar flexion, inversion and eversion motion for smooth symmetric gait performance and energy capture and return. The socket, pylon and foot-ankle complex are portions of a unibody.
