Abstract: A unitary foot and shin component for a lower limb prosthesis has a one piece thermoplastic endoskeletal foot keel and shin member and a continuous flexible cosmesis. The cosmesis includes a resilient foot body which is molded directly onto the keel so as to embed the keel, and an integral flexible and hollow shell which surrounds the shin member but is spaced from it. By forming the foot body and the hollow shell as a single polyurethane molding, the foot and shin can be supplied as a single component, ready for connection to a stump socket and alignment coupling.

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.
