Abstract: A knee joint orthosis having a thigh part, which is to be attached to the igh by harnesses or the like, a lower leg part, which is likewise to be attached to the lower leg by harnesses or the like, and two joint splints which are located laterally opposite each other and connect the two leg parts with each other in an articulated manner. To improve the function as well as the construction design, according to the invention, each of the two joint splints is constructed so that it is telescopically adjustable in length, and is coupled at its upper end to the thigh part and at its lower end to the lower leg part, and a device is provided which effects a dorsalization of the lower leg by the retroposition of the joint splints.

Abstract: A heating enclosure for the production of thermoformed plastic shanks having a relatively uniform wall thickness, in particular for the production of prostheses, is provided.

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.

Abstract: An ankle joint brace with a dorsal leg shell extending over the back of the oot, which can be fastened by strappings or similar devices to the calf. In order to improve the function and the structure of this ankle joint brace, the leg shell is extended by a frontal shell section underneath the sole of the foot and, in the area of the ankle joint outer ligaments, it is taken inward and tapered sharply toward the back, creating a cut-out, and an elastic rubber tensioning strap holds the leg shell with a dynamic pull, underneath and outward on the frontal shell section on one side and inward and above in the calf area on the other side, the leg shell being flexible in dorsal extension and pronation because of its shape, while the tensioning strap restricts supination and plantar flexion.
