INTRODUCTION We analyzed the functional prostheses including body powered prosthesis1 produced for partial hand amputation. There are almost no solutions on the  world market for patients with partial hand amputation. There is no final solution for stump socket (inner socket) that could present both comfort for the stump and cosmetic look of the socket, and at the same time had partial possibility to take the load and transfer it to the power unit.2,3 Abstract PDF  Link: https://jps.library.utoronto.ca/index.php/cpoj/article/view/32026/24443 How to cite: Kruglov A, Lein G, Shvedovchenko I.
