ABSTRACT:
A prosthetic leg is characterized by an elongated, flat pylon operatively secured at its upper end to the wearer's leg and at its lower end to a prosthetic foot. The pylon is constituted by one or more leg elements which are fabricated from polymer impregnated and encapsulated laminates, including such laminates as carbon fibers and/or fiberglass or synthetic fibers such as Kevlar. The demountable connection of the leg elements permits interchangeability of leg elements to match the weight, stride and activity schedule of the wearer utilizing the prosthetic leg. Deformable adjustment means is provided in juxtaposition to said leg elements whereby the flexibility of said pylon may be adjusted. To achieve or improve the desired flexure and energy-storage characteristics, the leg elements may be formed in a concavo-convex configuration.
