<p>An orthopaedic and orthotic bipivotal hinge assembly 10 has a hinge body 11 and a pair of coplanar and independently-pivotal hinge arms 12, 13. The proximal end portions 12a, 13a of the hinge arms are disposed within the hinge body (11) and have at least one set of interdigitating end plates 12b, 13b defining an arrangement of abutment surfaces 12c, 13c that are coplanar, face generally in the same direction, and are disposed in side-by-side relation when the arms (12, 13) are in first positions of adjustment (for example, extension). A second embodiment provides two sets of interdigitating plates with two arrangements of abutment surfaces for controlling both extension and flexion. Continuously variable extension and/or flexion control is achieved by an adjusting screw, or a pair of adjusting screws, carried by the hinge body.</p> |
