1. A hinge comprising:
a first arm;
a second arm;
a hinge plate, the first arm connected to the hinge plate for rotation about a first axis and the second arm connected to the hinge plate for rotation about a second axis, the hinge plate including an internally threaded aperture;
a force application assembly;
an adjustment assembly including
an externally threaded lead screw engaged with the internally threaded aperture of the hinge plate and having
a medial end connected to the force application assembly, and
a keyed bore extending along a longitudinal axis of the externally threaded lead screw from a lateral end of the externally threaded lead screw toward the medial end,
a drive key having a keyed shaft slidingly engaged with the keyed bore,
a knob connected to a lateral end of the drive key such that rotation of the knob causes rotation of the drive key which causes rotation of the externally threaded lead screw through engagement of the keyed shaft and the keyed bore, wherein the rotation of the externally threaded lead screw causes the externally threaded lead screw to move laterally or medially along the longitudinal axis relative to the hinge plate and the drive key to cause lateral or medial displacement of the force application assembly, and wherein the keyed bore slides laterally or medially along keyed shaft of the drive key as the keyed bore and the keyed shaft rotate together, and
a cover having an opening positioned on an anterior side or a posterior side of the cover, wherein the knob and drive key are positioned between the cover and the hinge plate, and wherein the knob extends at least partially through the opening.
