Abstract: The invention relates to a prosthesis for a leg amputee, comprising a thermoformed framework made of a thermoplastic material or of a laminated substance, covered with a coating material and comprising a socket (1), a leg part (2) and a prosthetic foot (3), one adjoining the other.According to the invention, the framework of the leg part (2) and the prosthetic foot (3) constitutes a monobloc assembly, produced in a single casting operation, and in that the prosthetic foot comprises, at the level of the sole, a cut having served for the extraction of the molding core and, at the level of the heel, above the sole, a cut (9) of wedge formation lending itself to a flexion of the rear of the sole relative to the leg part.

Abstract: The invention relates to an apparatus for plotting the conformation of a lower limb of the human body, this apparatus comprising two sets of two longitudinal uprights, or splints (1), the splints of one and the same set being mutually articulated by an orthesis articulation (2) of a known type, and a plurality of cross-pieces forming braces (8, 10, 12) which transversely connect the splints (1) at various intervals. According to the invention, the spints (1) are deforable in such a way that they can be applied tighlty agains the limb in question in order to match the profile thereof, and the crosspieces (8, 10, 12) connecting these splints have an adjustable transverse dimension, so as to be able to regulate the spacing of the splints.

Abstract: The invention relates to a prosthesis for amputation of the leg.This prosthesis comprises, in monobloc form:a socket (1) of a thermosettable resin, preferably provided with reinforcement fibers;a hollow leg element (2) rigidly integral with the socket, likewise of a thermosettable resin, preferably provided with reinforcement fibers;a hollow foot part (3) rigidly integral with the leg element (2), and in which is lodged a rigid core (26) of a foam of plastic material or similar, this foot part being likewise of a thermosettable material, preferably provided with reinforcement fibers;a sole element (4) of a thermosettable resin, preferably provided with reinforcement fibers, closing the hollow foot part at its base.

Abstract: The device for the alignment research, the alignment and orientation of a first portion of a prosthesis with respect to second portion of said prosthesis comprises at least three elements, two of said elements having spherical contact surfaces and two of said elements having flat contact surfaces, said elements being interposed between said first and second portions of prosthesis and moved one with respect to the other to adjust the respective positioning and orientation of said two portions of prosthesis.
