ABSTRACT:
An artificial ankle and foot is disclosed. The ankle and foot comprise a tibia, a rear-midfoot, and a forefoot (toes), which contact each other at cam surfaces. Extensible elastic ties interconnect the tibia and rear-midfoot and the rear-midfoot and the forefoot. The ties are attached to the respective components at points or zones of attachment which are movable with respect to each other in accordance with the forces acting on the foot and ankle and the rolling motion of the cam surfaces. The relative movement of the zones of attachment alters the tension in the elastic ties, thereby limiting or increasing mobility in the joints between the tibia and rear-midfoot and between the rear-midfoot and the forefoot.
