Abstract
An orthopedic device has first and second struts connected to one another by a hinge system, and includes a dynamic control system and a counterforce system. The dynamic control system includes first and second dynamic components arranged on a first side of the orthopedic device to exert first and second dynamic forces according to a flexion angle of the hinge system. A counterforce system is located on a second side of the orthopedic device to counteract the first and second dynamic forces with at least one counterforce.
Claims18
An orthopedic device having first and second struts connected to one another by a hinge system including at least one hinge, comprising:
- a dynamic control system including:
- a first dynamic component arranged on a first side of the orthopedic device relative to an anterior-posterior plane, and superior to the hinge system, the first dynamic component connected to at least one of the first and second struts and arranged to exert a first dynamic force directed toward at least one of the first and second struts according to a flexion angle of the hinge system, a first cable securing to the first dynamic component and extending along the first strut and past the hinge system and anchored to the second strut;
- and
- a second dynamic component arranged on a first side of the orthopedic device relative to an anterior-posterior plane, and inferior to the hinge system, the second dynamic component connected to at least one of the first and second struts and arranged to exert a second dynamic force, directed toward at least one of the first and second struts according to a flexion angle of the hinge system, a second cable securing to the second dynamic component and anchored to the at least one hinge;
- a counterforce system located on a second side of the orthopedic device relative to an anterior-posterior plane and adapted to counteract the first and second dynamic forces, the counterforce system including a first counterforce strap device coupled to the second strut and inferior to the hinge system for providing a first counteracting force to the first dynamic force, and a second counterforce strap device coupled to the first strut and superior to the hinge system for providing a second counteracting force to the second dynamic force;
- wherein the first and second cables are separate and independently adjustable relative to one another;
- wherein the first cable freely extends over the hinge system without interference with movement of the first cable as the hinge system articulates;
- wherein the first cable consists of and terminates at first and second ends with the first end securing to the first dynamic component and extending along the first strut and past the at least one hinge inferiorly to the hinge system.
