Abstract
Instrumentation and methods are provided for upper jaw correction surgery. The application discloses an orthopedic system and method that can be used to perform both a first distraction (for example a maxillary distraction) and a second distraction (for example a maxillary expansion) within the same surgical procedure. The instrumentation for separating first and second bone segments can include a first footplate; a second footplate; an actuator arranged to vary a distance between the first and second footplates; and a hinge that rotatably attaches the first and second footplates such that the first and second footplates can be angularly adjusted relative to each other about a pivot axis. Additionally, instrumentation and methods are provided for a hinged fixation device capable of securing and adjusting both the linear separation and angular orientation of bone structures.
