ABSTRACT:
A device for joining a prosthetic appendage to a prosthetic limb, comprising rotatable bearings encased within a cylindrical sleeve of resilient material, the cylindrical sleeve having its long axis colinear to the axis of rotation of the bearings. The bearings have a proximal portion affixed to the end of the limb, and a distal portion affixed to the appendage at the point where it is to be joined. The resilient sleeve comprises a top portion which is affixed to the outside surface of the proximal portion of the bearings, a bottom portion which is affixed to the outside surface of the distal portion of the bearings, and a typically bulging central portion which is not affixed to any part of the bearings. When the appendage is rotated relative to the limb about the axis of the bearings, such rotation is resiliently resisted by torsional flexure of the central portion of the resilient sleeve.
