The lack of dexterity-restoring 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 two degree of freedom passively actuated index finger, one degree of freedom actuator plus sensor driven thumb, solenoid locking system, and passive variable compression bladder. Both qualitative and quantitative testing has demonstrated that this device partially restores several gripping capabilities of the amputee.
