Abstract: A foot lifter orthosis including a dorsal leg shell, extending over the rear foot, which can be fixed by a strapping means to the calf of the orthosis wearer and which has a forefoot shell section constructed in one piece which extends to a point below the foot sole region, wherein the leg shell exhibits a low resistance in dorsal foot bending and a high resistance compensating for the foot and shoe mass in plantar foot bending with at least one resilient inlay, which extends approximately parallel to and at a short distance from an edge of the leg shell from the calf region thereof to a point below the forefoot shell section. An associated method of formation is also disclosed.

Abstract: A foot prosthesis has an inner spring that extends from the heel area to the front area of the foot. The foot spring is enclosed within a cosmetic lining and is joined by a threaded bolt to an adapter with a clamping connection for removably joining the foot prosthesis to a prosthesis tube. The adapter is supported by its lower face, which is designed as a cylinder segment and is provided with serrations, on a joining surface of the inner spring. The joining surface of the inner spring has a shape corresponding to the lower face of the adapter, and has serrations for engaging the adapter's serrations. The upper end of the adapter is designed as a peg which is inserted into the prosthesis tube. The threaded bolt is inserted through a slot that extends in the longitudinal direction of the foot and has a width corresponding to the diameter of the bolt.

Abstract: A prosthetic foot includes a prosthesis body having a toe region disposed in a front part of the prosthetic foot, and a one-piece insert which is provided in the prosthesis body and which absorbs and transmits stresses imposed on the prosthesis body. The insert enables at least a plantar and dorsal deflection as well as axial compression of the prosthesis body, and has an approximately S-shaped design in the longitudinal section of the prosthetic foot. The insert includes a top horizontal section which forms a top edge of the prosthetic foot, and a bottom horizontal section which is of an extended construction compared with the top section and which has a free end which extends into the toe region of the prosthesis body, so that a high elasticity and a high energy storage capacity of the front part of the prosthetic foot are achieved. A front inclined section extends at an obtuse angle from the top section to form a rigid angular element.

Abstract: An inner conical recess fitting (1) which is connectable to the prosthesis and is intended for receiving a stump (17) of an amputated extremity can be fitted directly to the stump (17) without the aid of modeling in the following procedural steps: to mold the inner conical recess, a plastic which is shrinkable through the action of external influences, such as heat, is selected; a tube (14) which is made of this plastic and is open at at least one end and has a smaller diameter and a smaller length than the inner conical recess fitting (1) to be manufactured is extended and stretched, so that it has in every direction a greater dimension than the inner conical recess fitting (1) to be manufactured; and the widened and stretched molded piece (10) is placed on the stump (17) and is made to shrink through, e.g., application of heat at selected locations, until the fitting bears everywhere securely against the stump.

Abstract: In an orthopedic device for treating hip dysplasia and hip dislocation, a pelvis-supporting portion is provided with two angular projections extending in the region of natural hip joints of a patient and each carrying a pivot joint including rotation discs to which a curved guide is connected. The curved guide of each pivot joint has a longitudinal slot in which an end of an upper shank guide bar is displaceable and arrestable in any desired position. Two upper shank guide bars carrying the respective upper shank supports are pivotally connected to the lower shank guide bars carrying the respective lower shank supports.
