Abstract:
A dynamic prosthetic foot having multiple load points and a single upper, comprising:a sole having a heel end and a toe end that are in substantial coplanar relation to one another; an upper member that overlies said sole, said upper member having a heel end and a toe end; said upper member having a gradual ninety degree bend formed therein, said gradual ninety degree bend separating said toe end of said upper member from said heel end of said upper member, said heel end of said upper member separating from said toe end of said upper member along a parting line that is transverse to a longitudinal axis of said prosthetic foot; a slot formed in said heel end of said upper member, said slot substantially coincident with the longitudinal axis of said prosthetic foot and said slot extending from an uppermost end of said heel end of said upper member to a point about mid-way of said gradual ninety degree bend; said slot dividing said heel end of said top member into a lateral pylon support and a lateral section of said upper member and into a medial pylon support and a medial section of said upper member; said pylon supports being disposed substantially perpendicular to said sole; whereby forces acting on said lateral pylon support are substantially confined to said lateral pylon support and said lateral section of said upper member and forces acting on said medial pylon support are substantially confined to said medial pylon support and said medial section of said upper member; whereby forces acting upon said lateral section of said upper member are substantially attenuated when transmitted to the medial section of said upper section; and whereby forces acting upon said medial section of said upper member are substantially attenuated when transmitted to the lateral section of said upper section.
