The lack of partial hand prosthetics for amputations at the metacarpophalangeal joint has necessitated the development of a solution that bridges this gap in prosthetic technology. This is addressed via a case study involving a patient with an amputation at the metacarpophalangeal joint of their index finger and nearly complete amputation of the proximal phalanx of the thumb. The resulting solution consists of a servo-driven artificial thumb controlled by motion in the residual bone fragment of the patient’s biological thumb, and a passively actuated index finger controlled by the motion of the patient’s middle finger, with special focus on form factor, mechanical simplification, and improving on various shortcomings of the previous versions. Qualitative and quantitative testing indicates that the prosthetic restores several manual capabilities to the amputee. This project is a continuation of Partial Hand Prosthesis, advised by Professor Marko B Popovic, submitted on May 5, 2021.
