Orthopaedic hinge mechanism

摘要

An orthopaedic hinge mechanism has a body with at least one pivot and at least one hinge arm mounted thereon and having two cam abutment stops which arise from the said hinge arm either side of and close to the pivot. Screw adjustment means are housed in threaded holes in the hinge body in the plane of the hinge arms and may be driven down to impinge on the cam abutment stops. The plane of the operating surfaces of the cam abutment stops is at right angles to the axis of the motion limiting screws. The mechanism provides limiting and locking possibilities over a clinically useful range.
