Abstract: Disclosed is a finger prosthetic is provided that could be attached to an individual's hand. The finger prosthetic includes a midsection, a fingertip portion, and a ring. The midsection, the fingertip portion, and the ring could be 3D printed and customized via 3D scanning The finger prosthetic includes a torsion spring system that comprises a fabricated torsion spring, a cable, and a pin. When the individual flexes their PIP joint, tension is generated in the cable and the cable pulls on the prosthetic fingertip thus flexing the prosthetic DIP joint simultaneously. When the individual wishes to extend the prosthetic DIP joint, he/she simply extends the PIP joint, causing the torsion spring to extend the prosthetic DIP joint. When the PIP joint is at rest, the cable will release the tension and the torsion spring will cause the DIP joint to extend to its upright position.
