Abstract

A hinge is provided for an orthopedic brace having an adjustable range of rotation. The hinge includes an outer member and an inner member that are rotatably connected in parallel alignment to one another. The peripheral edge of the outer member has a plurality of rotation limiting notches formed therein and the peripheral edge of the inner member has a rotation limiting face formed therein that is selectively alignable with one of the rotation limiting notches. Each of the peripheral edges also has a locking notch formed therein that is selectively alignable with the other. A rotation limiting stop is provided at the peripheral edge of the inner and outer members that is selectively positionable in one of the rotation limiting notches to define an adjustable range of rotation during a rotation mode of hinge operation. Rotation of the inner member is limited when the rotation limiting face engages the rotation limiting stop positioned in the selected notch. Alternatively, the rotation limiting stop is selectively positionable in the locking notches to lock the hinge against rotation in a locked mode of hinge operation. The hinge also includes a stop retainer, which retains the rotation limiting stop in the selected rotation limiting notch or locking notch during a rotation or locking mode of hinge operation, respectively, and which enables repositioning of the rotation limiting stop in an alternately selected rotation limiting notch during an adjustment mode of operation.
