Abstract
A lower extremity prosthesis solves the problem of relieving the end of the leg stump (S) from a portion of the vertical forces acting on it by pressure from the socket (1) surrounding and supporting the stump, by providing a mechanism capable of transferring forces to the tibia (T). The mechanism includes a first member (13) connected to the tibia and second members (5, 8) detachably connected to the first member and carried by the socket.
