A system of extension prostheses

Abstract

Congenital lower-limb deficiencies, which have not been converted by amputation, usually present with shortening as well as deformity and joint defects. It is normal practice to equalize the length by the use of a bootee, prepared from a cast, which is attached to a platform mounted above appropriate prosthetic components. In writing the prescription for the prosthesis (Fig. I), con

The prosthetic treatment of lower limb deficiency

“…In most cases the size and shape of the child's foot requires lhat the socket is opened to allow access, often by the use of a suitably reinforced leather bootee. Day and Wright (1977) described the relationship between the clinical factors and prosthetic prescription and demonstrated how this could be achieved using glass reinforced plastic prostheses to replace traditional leather and side-steel construction. Access to the rigid socket was achieved in one of two ways, either by a removeable access panel as in the Canadian Syme prosthesis (Foort, 1956), or by splitting the socket into anterior and posterior halves hinged together at the toe (Fig.…”
