Hinged fixation devices for combined upper jaw correction

A method of moving a first bone fragment relative to a second bone fragment using a distractor, the method comprising the steps of:

• pivoting a first footplate of the distractor about a first hinge relative to an actuator of the distractor about a first axis, wherein the actuator is elongate along a longitudinal direction and the first axis is oriented in a perpendicular direction that is perpendicular to the longitudinal direction;
• attaching the first footplate to the first bone fragment;
• pivoting a second footplate of the distractor about a second hinge relative to the actuator of the distractor about a second axis that is both parallel to the first axis and aligned with the first axis with respect to the longitudinal direction;
• attaching the second footplate to the second bone fragment;
• rotating a screw of the actuator relative to a sleeve of the actuator about a central axis that is oriented along the longitudinal direction wherein the rotating step causes the second footplate to translate along the actuator relative to the first footplate,
• wherein the second axis intersects the sleeve, and the second hinge overlaps opposed ends of the actuator along the perpendicular direction at two opposed regions of overlap, such that the actuator is received between the two regions of overlap.
