ABSTRACT:
A composite prosthetic foot and leg which allows a high degree of mobility on the part of an amputee is disclosed. The prosthetic foot and leg utilizes a resin impregnated high strength filament structure for the leg portion, the foot portion and heel portion, with all three regions being provided with substantial elastic flexibility, preferably of relatively low energy absorption characteristics so as to give the wearer high mobility with a relatively natural feel. All three portions of the prosthetic foot and leg are rigidly joined, with a flexibility of the leg portion providing flexibility of the leg in response to both torques about the ankle as well as about a vertical axis while simultaneously providing sidewise rigidity of the structure. Various embodiments are disclosed.
