Mechanical evaluation of the “Hüfner hand” prosthesis

Prosthetics & Orthotics International, 2020
Background: Current body-powered hands have very low acceptance rates. They also require high activation forces. In the past, a high acceptance rate was reported for the then-available Hüfner hand, a hand which could be controlled by relatively low activation forces.

The mechanics of the knee and prosthesis design [PDF]

The Journal of Bone and Joint Surgery. British volume, 1978
The mechanisms controlling and limiting movement and serving to transmit load between the femur and the tibia are discussed. Having accounted for the transmission of all components of force and couple across the joint and noted the load-bearing role of the menisci, some principles which might guide the design of knee prostheses are deduced.
