Abstract
A true bipivotal hinge for orthopaedic use having a hinge body and a pair of hinge arms with adjacent end portions pivotally connected to the side walls of the body for independent pivotal movement of each arm. A T-shaped insert element is removably secured within the hinge body and has a pair of stop portions with abutment surfaces engagable with the end portions of the arms for limiting the degree of extension of such arms. In a system for accommodating such a hinge to a patient's needs, a plurality of insert elements are provided, each being of substantially the same size and shape but having distinctive angularity of their abutment surfaces so that by interchanging one insert element for another, the hinge may be adjusted to provide the required degree of maximum arm extension.
