Abstract: A multi-centric orthopedic joint having inner and outer guide plates and upper and lower arms rotatably connected to the guide plates for pivotal movement therebetween. The plates each include upper and lower pairs of curved bean shaped slots, tilted relative to one another. The arms include a proximal end, the proximal end further including pins positioned and proportioned for complimental sliding movement within the upper and lower slots of the guide plates. Set screws are positioned between the inner and outer guide plate against a locking surface of the proximal end of each arm. When the set screws are loosened the upper and lower arms may be moved relative to one another, permitting the guide pins to slide within the slots but in opposite directions relative to one another. Flat-screws secure the inner and outer guide plates and co-act with the set screws as a locking mechanism of proximal ends of said arms at a desired angulation between them.

Abstract: The invention relates to an orthopedic hinge system, including an outer and an inner lateral base, each substantially complemental in peripheral dimension to each other, the bases each having a major vertical axis, the inner base having a recess. Also included is an elongate distal member having a semi-circular pivot end including, upon a portion of the end, ratchet teeth pointing in a counter-clockwise direction, the pivot end rotationally secured to both of the bases. Further included is an elongate proximal member having a transverse end element proportioned for complemental securement within the recess of the inner base, transverse end element including an axis of rotation co-linear with an axis of rotation of the distal member and defining an axis of rotation of the pivot end of the distal member.

Abstract: A hinge joint includes a first planer element and a second planer element, each of said planer elements having an exterior side and an interior side. Each planer element exhibits an opening for axial rotational attachment about an end of an intermediately rotationally secured third planer element. The first and second planer elements are secured, at a defined offset by several bolts. Such offset is proportioned to permit rotation of the end of the third planer element therebetween. The interior surfaces of the first and second planer elements are provided with linear channels within which are placed springs, the function of which is to regulate the angulation and resilience of the third planer element relative to the mutually secured first and second elements of the hinge joint.

Abstract: There is provided a knee brace having a primary joint and a flexible secondary joint. The brace permits a more natural flexibility of the knee and lower leg, both when the lower leg is co-linear with the upper leg and when the lower leg is bent relative to the upper leg, as in the case during the sitting.

Abstract: There is disclosed a bi-centric joint for use in an orthopedic support system which includes a plurality of interdigitating tubular elements, secured upon planar base means, in which hubs from which said tubular elements project are secured to proximal and distal sections of the orthopedic apparatus. The length of each interdigitating tubular radial spoke is such that, upon the passage of said spoke through a centerline defined by the centers of rotation of the hubs, a pivot action at the end of such spoke against a peripheral surface of said proximal or distal section will occur. The result is a simulation of natural movement of a human joint.
