  • Patent number: 5211667
    Abstract: A prosthesis for guarding a residual limb after a lower limb amputation includes an upper shell, lined with a soft material, and matching the limb residuum. A lower shell telescopes over the upper shell. Each shell has a slot in its lower end. A first high density foam pad is disposed in the lower shell such that the lower end of the upper shell rests thereon. The patient dons a stump sock having an elongate thin strap at its distal end. The strap is threaded through a second soft plastic foam pad, the slot in the lower end of the upper shell, the high density foam pad in the lower shell, and through the slot in the lower end of the second shell. Fasteners are provided for anchoring the strap to an external surface of the lower shell. The shock due to a patient falling on the residuum is absorbed by the lower shell telescoping further over the upper shell to permit the pads to compress, as well as by the compression of air between the shells.
