Unibody Endoskeletal Transtibial Prosthetic Devices and Digital Fabrication Workflow

A method for producing a unibody transtibial prosthetic device, the method comprising:

• acquiring patient data via imaging and/or scanning;
• constructing a 3D model from the patient data;
• translating the 3D model to 3D printable design of a unibody transtibial prosthesis;
• and
• 3D printing the unibody transtibial prosthesis;
• wherein:
• the unibody transtibial prosthesis comprises a pylon and a foot-ankle complex;
• the pylon has a unitary truss structure formed of a plurality of elongated supports interconnected at nodes;
• and
• the foot-ankle complex extends from a base of the pylon and comprises:
• i) a sole portion;
• ii) an s-shaped posterior portion extending from a first location on the sole portion to the base of the pylon;
• and iii) an s-shaped anterior portion extending from a second location on the sole portion to a terminal portion of the s-shaped anterior portion near the base of the pylon, the terminal portion being unconnected to the base of the pylon.
