Abstract

A prosthetic socket system comprising a prosthetic socket and a liner, said prosthetic socket having a distal end region, at least one socket wall extending therefrom in proximal direction, and connection means for securing a prosthetic component. The socket wall, when in the applied state, at least partially enclose a stump that is received in the prosthetic socket The liner includes a proximal entry opening and a lateral wall which extends in the distal direction, at least partially surrounds a stump when in the applied state and is arranged between the stump and the prosthetic socket when in the applied state. A coupling device is arranged between the liner and the prosthetic socket in the distal end region, and, on the outer side of the lateral wall of the liner and on the inner side of the socket wall, resistance regions are arranged or formed which interact with one another and which counteract a movement extracting said liner out of the prosthetic socket, in the proximal direction.
