Abstract: A liner of a limb prosthesis liner includes a main body portion, an open proximal end, and a closed distal end. The liner further includes a sealing rib. The sealing rib has a first portion spiraling around the liner.

Abstract: An alignment assembly for a modular prosthesis. The alignment assembly includes a plurality of modular components that can be selectively connected to each other for providing selectively linear adjustability along first and second non-parallel axes, and rotational/angular adjustability about three orthogonal axes.

Abstract: A prosthesis liner for below-knee amputees comprising a polymer liner, such as silicone, incorporating a pre-flexed shape having an angle at the knee selected from 20 to 60 degrees, at least one thickened upper silicone band, an appropriate anatomical shape and taper and a flexible connector piece at the bottom portion of the liner adapted for connection to a walking piece. An anti-bacterial agent is added to the liner to suppress the over-growth of bacteria that may form between the liner and the residuum.

Abstract: A plastic orthotic therapeutic device which applied correcting pressure for varus or foot inversion and equinus or foot drop. This combination is prevalent in a condition known as spastic equinovarus which occurs with alarming frequency in post-stroke and brain injured patients. Equinus is controlled by a three pressure point system consisting of a foot plate, a broad proximal posterior section and the wearer's shoe. Varus is controlled by a three point pressure point system consisting of an appropriately relieved and padded malleolar area, a high medial wall, an extended projection proximal to medial malleolus, and an extended trim line over the first tarsal bone of the wearer. This orthosis is made of lightweight, hygienic polypropylene and may be worn inside the patient's shoe. It is easily donned and doffed using only one hand.
