摘要：The present invention is a lower extremity prosthetic device which includes amodular foot having a heel member and an elongate, dorsal midfoot member configuredfor detachable combination via a coupling mechanism. The heel member is formedsubstantially from a first structural material of a first modulus of elasticity. The midfootmember is formed substantially from a second structural material having a secondmodulus of elasticity less than the first modulus of elasticity. The midfoot memberextends arcuately forwardly from the heel member, and is configured with differentiallyflexible lateral and medial elements which provide the device with flexion characteristicssimilar to those of a natural foot. An elongate plantar member extends between the heelmember and a forward end of the midfoot member, the plantar member being formedsubstantially from a third material having a third modulus of elasticity which is lower thanthe second modulus of elasticity. The plantar member includes a toe section and a sub-arch section. The sub- arch section extends arcuately between the heel member and theforward end of the midfoot member. The toe section extends forwardly from the sub-arch section.
