Abstract
An orthopaedic and orthotic bi-pivotal hinge assembly having a hinge body and a pair of coplanar and independently-pivotal hinge arms. The proximal end portions of the hinge arms are disposed within the hinge body and have planar abutment surfaces that face in the same direction and are disposed immediately adjacent each other when the arms are in full extension. Continuously variable extension control is achieved by an adjuster screw carried by the hinge body that is engageable with both of said planar abutment surfaces of said arms.
