Abstract: An apparatus for joining two members, comprising a central assembly within a first housing, the central assembly comprising a rotor or rotational member, a pin attached at one end to the rotor or rotational member, a base circumferentially disposed about the pin and attached thereto, a resistance member in connection with the pin, at least one compression member in connection with the resistance member, at least one intermediary member disposed between the at least one compression member and the base, a second housing in connection with the pin and first and second arm mechanisms attached at opposing distal ends of the pin.

Abstract: An upper extremity prosthetic device is provided that comprises three main components, namely, an arm cuff, a forearm section and a distal connector. The arm cuff is adjustable to accommodate lower arms of different sizes. The forearm section may be constructed in certain limited sizes to accommodate different sized forearm residual limbs. The distal connector is designed to connect to any of the forearm section configurations, and the distal connector enables any terminal device to be attached to the connector. The components may be mixed and matched in various combinations to fit the physical dimensions of virtually any amputee. The interchangeable parts will accommodate a wide range of residual limb geometries, overall sizes and lengths. Embodiments of the present invention minimize the need for time and resource-intensive customized fitting and create an affordable, relatively low-cost prosthetic interface.
