ABSTRACT:
An improved above-the-knee prosthesis with an anatomically configured socket is characterized by one or more contours which correspond to a pre-selected anatomical contour of the upper or lower residual thigh. By exaggerating the depth of the contour in the socket as compared with the corresponding contour in the thigh, the socket grips the residual thigh and maintains the femur in proper alignment. The new channels and contours allow the patient using the socket to have improved rotational support and control over the prosthesis by providing structures which the muscles of the upper and lower residual thigh can "grip." The socket snugly contains the thigh and maintains it, throughout the gait cycle, in a proper anatomical position. This fit increases the comfort of the prosthesis and minimizes gait abnormalities common with other artificial limbs. The increased support helps maintain the physical condition of the residual limb. The extended and new channels allow the muscles of the patient's residual thigh to flex and contract against and around the channels, thereby reducing muscle atrophy.
