ABSTRACT:
A prosthetic foot adapted to be attached to a standard sized pylon defining a lower surface and an interior surface which defines a cavity. The foot includes a horizontal foot portion, an upstanding ankle portion connected to the foot portion and a plug formed around the upper end of the ankle portion. The plug defines a radially extending flange spaced downward from the top of the plug and a mating portion above the flange.
A mating portion of the plug fits within a cavity defined by the interior surface of the pylon. A layer of adhesive is provided between the interior surface of the pylon and the mating portion of the plug so that the interior surface and mating portion form a tight fit and the layer of adhesive forms an adhesive bond. The adhesive bond resists torsional load and the mating portion of the plug and the pylon cooperate to resist sheer forces.
