Unibody endoskeletal transtibial prosthetic devices and digital fabrication workflow

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

• acquiring patient data via imaging and/or scanning;
• constructing a three-dimensional (3D) model from the patient data;
• translating the 3D model to a 3D printable design of a unibody transtibial prosthesis;
• 3D printing the unibody transtibial prosthesis;
• wherein the acquiring patient data comprises imaging a contralateral limb and a residual limb;
• wherein the imaging is conducted with a smart phone;
• wherein the 3D printing prints a unitary socket, pylon and foot and ankle, the pylon has an open structure of interconnected elongated supports having open spaces therebetween and the foot has a split ankle, a split toe and a split heel;
• and
• wherein the 3D printing is a multi-material printing process that forms regions of different stiffnesses in the unitary socket, pylon and foot and ankle.
