<p>An articulated prosthesis includes first (10) and second stem (10a) members each anchored to a bone member at one of the ends of the stem member, and the stem member having 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 (12), and ball (14) combination. The socket has a generally spherical configuration with a hollow interior (23), and a rectangular access port to the interior. The socket has one surface portion (20) 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 surface portion (20d) 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 (28) on the ball provides a limiter for rotational, and axial movement of the ball within the socket so that the prothesis imitates the natural movement of a finger or toe.</p> |
