Abstract: An artificial limb has an endoskeletal shin component which is of generally constant H-shaped cross section and is formed by injection molding from thermoplastics material. In a preferred embodiment, the limb has a foot keel which is integrally molded with the shin component. The keel also has upper flanges which are contiguous with anterior and posterior flanges of the shin component. Such a limb can be made light in weight yet strong in terms of resistance to transverse bending moments, and can be inexpensively produced. The constant cross section of the shin component allows it to be cut to a required length and clamped to an upper limb component.

Abstract: A single-piece fibre-reinforced plastics shin component for a lower limb prosthesis for a below-knee amputee has an elongate resilient energy-storing blade and, integrally formed at a proximal end of the blade, an alignment plate extending generally anteriorly and perpendicularly with respect to the blade to form at least part of an alignment device for adjusting the position of the blade relative to an upper limb component. The blade is straight and of constant cross-section at least over its distal end portion to allow it to be cut to length to suit the amputee.

Abstract: A single-piece fibre-reinforced plastics shin component for a lower limb prosthesis for an above-knee amputee has an energy storing blade and, integrally formed therewith, a shin cradle in the form of a channel section which has a pair of pivot supports formed as flanges extending away from one of the major surfaces of the blade. Each flange has a pair of holes defining transverse pivot axes, one of which is a knee axis and the other of which is a pivot axis for mounting the distal end of a knee movement control unit. These holes together define a longitudinal axis which is generally parallel to and to the anterior of the blade. The blade merges smoothly into the channel section and, over a distal end portion, is straight and of constant cross-section to allow the blade to be cut to length to suit the amputee.
