Description

ABSTRACT:
A foot prosthesis is provided for attaching to a socket or pylon fitted to the stump of an amputee. The foot prosthesis includes a forefoot portion constructed of a resilient polymer-encapsulated fiber laminate and having an upper attachment section, a curved intermediate section and a lower forward extending section. The shape of the forefoot is generally parabolic or J-shaped so as to provide smooth resilient support to the amputee during normal walking and running activities without producing undue stress concentration in the prosthetic foot, which could otherwise degrade the integrity of the foot. An arcuate toe section provides smooth rolling contact of the foot prosthesis with a ground surface during toe-off, simulating the stride and feel of a natural human foot. A heel portion, also formed of a resilient polymer encapsulated laminate material, attaches under the forefoot in order to provide enhanced comfort and energy absorption during heel-strike. The strength and resilience characteristics of the forefoot and heel portions may be adjusted by interchanging like elements so as to accommodate amputees having different sizes, weights and activity levels.
