Abstract: Embodiments of the present invention relate to determining the overall height of a prosthesis composed of several components, in which at least some of the components can be adjustably connected to one another via adapters using a substantially spherical surfaces. In certain embodiments, each component can be assigned a system height value and for some components the system height values are adjustable by means of a substantially spherical surface. In other embodiments, a midpoint dimension can be assigned in the respective substantially spherical surface, and these system height values for the components mounted on one another can be added together to determine the overall height.

Abstract: A below-knee prosthesis in which an adapter is displaceable and fixable in relation to the lower socket end on a circular segment surface whose circular arc lies in the sagittal and frontal plane and whose midpoint is the center of the knee.

Abstract: The invention relates to a tubular adapter for clamping connection with the end of a tubular part (4) of a modular prosthesis. The adapter includes an axially slotted connecting sleeve (2) circumferentially clampable by means of a clamping bolt or the like and intended to receive tube end (4), with one end of said sleeve abutted by an annular coupling section (3) preferably having on its circumference four equally spaced threaded holes (5), each hole being designed to receive a coupling and adjusting bolt (clamping bolt) and having an annular ball socket (6) provided endwise to engage a ball collar of an adjusting core. The socket extends in the coupling position on a projection designed as a multi-surface pyramid into the clamping area of the clamping bolts.

Abstract: The invention relates to an artificial foot which is essentially composed of an incompressible core, a heel wedge, an inner foot and an outer foot surrounding everything.

Abstract: A connecting part of a ball joint between leg prosthesis components with a lange intended to fasten to the one component, the flange having an adjusting element position on it, consisting of a cup and a four-sided pyramid positioned centrally upon its point. To improve the adjustability of the connecting part, the flange is a rectangular flange with four holes, upon which the adjusting element is eccentrically positioned.
