ABSTRACT:
A prosthetic foot characterized by an easily exchangeable auxiliary ankle member demountably attached to forefoot and sole portions, which are in turn demountably and interchangeably connected. The forefoot, heel and auxiliary ankle portions are fabricated from polymer impregnated and encapsulated laminates, including such laminates as carbon fibers and/or fiberglass or synthetic fibers such as Kevlar. The easily demountable connection of the auxiliary ankle permits interchangeability thereof to match the activity schedule of the wearer utilizing the prosthetic foot without the necessity of frequent visits to the prosthetist. A compressible member between the forefoot member and the sole member, and function blocks located between the various members provide additional adjustability. The orientation of the auxiliary ankle member and compressible member also allows for increased plantar flexion.
