Hinge for orthopedic devices

A hinge for an orthopedic device, comprising:

• an upper hinge component having a bottom peripheral surface defined by a first geometrical configuration;
• a lower hinge component having a top peripheral surface defined by a second geometrical configuration;
• an outer plate pivotally connected at first location points to the upper and lower hinge components;
• a rear component pivotally connected at second location points to the upper and lower hinge components;
• a rotation stop fixedly secured to the rear component in constant relative position between the rotation stop and the rear component and between the upper and lower hinge components, the rotation stop having a third geometrical configuration defining a top portion corresponding in shape to at least a portion of the bottom peripheral surface and arranged to directly abut the portion of the bottom peripheral surface, and a bottom portion corresponding in shape to at least a portion of the top peripheral surface and arranged to directly abut the portion of the top peripheral surface, the rotation stop secured to at least two third location points to the rear component;
• wherein the rotation stop consisting of an extension stop and a flexion stop directly interlocking with one another at an anterior surface of the flexion stop and a posterior surface of the extension stop to make the rotation stop unitary, the extension stop is arranged to receive at least two different flexion stops, each having a different degree configuration, the flexion and extension stops combine to span a vertical distance between the upper and lower hinge components such that each of the flexion and extension stops contact the bottom peripheral surface of the upper hinge component and the top peripheral surface of the lower hinge component;
• and
• wherein the flexion and extension stops each consist of a singular integral element.
