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.
