ABSTRACT:
An articulated prosthesis includes first and second stem members each anchorable to a bone member at one of the ends of the stem member and the stem member having an aperture with a surrounding surface at the other end. Disposed between the first and second stem members is a movable joint part including a socket and ball combination. The socket has a generally spherical configuration with a hollow interior and a rectangular access port to the interior. The socket has one surface portion having a complementary configuration to the surrounding surface of the stem member ends for adjustable connection to one of the stem members. The ball has a circular configuration with a thickness configured to pass through the access port so that the ball can be rotated within the socket to encapsulate and secure the ball for rotatable motion. The ball has a surface portion having a complementary configuration to the surrounding surface of the stem member ends for adjustable connection to the other stem member. An arcuate extending tab on the ball provides a limiter for rotational and axial movement of the ball within the socket so that the prosthesis imitates the natural movement of a finger or toe.
