A special arrangement for limiting rack displacement is effective to selectively clamp the hinge arms at a given arm angle or to permit movement within a limited range of allowable angles.

A polycentric orthopedic appliance hinge comprising a pair of hinge arms each capable of angular displacement over a range of angular displacements about a respectively associated pivot axis; displacement means in the form of a driven member interposed between and connected to said hinge arms such that it is translated as a consequence of angular displacement of either one of said arms for forcing angular displacement of the other of said arms and such that the angle between the directions of said arms increases or decreases as the sum of their angular displacements; and stop means in the form of means for limiting displacement of said displaceable driven member for limiting displacement of said arms to a selected segment of said range of angular displacements.
