ABSTRACT:
A foam block ankle prosthesis for Symes amputees that has a lower foot plate and an upper ankle plate connected by a monolithic foam block. The foot plate is generally sized the same as a surrounding cosmesis, while the ankle plate is substantially shorter, with the foam block forming a resilient ankle region underneath the ankle plate. The plates are bonded to the foam block with suitable adhesive. An attachment member is fastened to an upper surface of the ankle member slightly rearward from its centerline and approximately located where a centerline of the wearer's ankle would be. During a walking stride the wearer experiences a smooth rollover or transition of compressive forces from a heel-strike position to a toe-off position.
