ABSTRACT:
An artificial leg has a ball and socket ankle joint, the socket of which has upper and lower portions. They are connected together and clamped over the ball by a turnbuckle ring. This provides an adjustable shin and foot connection which permits use of a rubber-encased ball of sufficient size, without taking up too much shape within the ankle region. Also disclosed is a movable patella member and a vertically jointed two part foam covering.
