ABSTRACT:
The present invention relates to a prosthesis having a substantially rigid leg member, wherein most of the bending takes place about a confined ankle region relatively low to the ground, and in a flexible toe and ankle section, wherein the bending of the prosthesis more closely resembles the bending of a normal ankle joint. The confined bending helps to reduce the amount of horizontal deflection caused along the ankle section by the upward deflection of the prosthesis. The present invention also comprises a tubular leg member that is detachable from the ankle and foot member, and a heel member extending rearwardly from the foot member which is also detachable therefrom.
