Abstract:
A dynamic prosthetic foot having multiple load points, comprising:a sole having a heel end and a toe end; a slot formed in said heel end of said sole, said slot substantially coincident with a longitudinal axis of said dynamic prosthetic foot and said slot extending from said heel end of said sole to a preselected point in said sole; said slot dividing said heel end into a lateral heel member and a medial heel member, said lateral heel member and said medial heel member being separated from one another by said slot; said lateral heel member including a lateral pylon support and said medial heel member including a medial pylon support; said lateral heel member being formed by a return bend formed in said sole at said heel end thereof and said return bend terminating in a ninety degree upwardly turned bend to form said lateral pylon support, said lateral pylon support being disposed normal to said sole; said medial heel member being formed by a return bend formed in said sole at said heel end thereof and said return bend terminating in a ninety degree upwardly turned bend to form said medial pylon support, said medial pylon support being disposed normal to said sole; a lateral pylon connector secured to a trailing end of said lateral pylon support, said lateral pylon connector adapted to receive a lateral pylon of a prosthetic leg; a medial pylon connector secured to a trailing end of said medial pylon support, said medial pylon connector adapted to receive a medial pylon of a prosthetic leg; whereby forces acting on said lateral pylon connector are substantially confined to said lateral pylon support and forces acting on said medial pylon connector are substantially confined to said medial pylon support; and whereby said foot exhibits enhanced heel elasticity.
