Osteotomy system and method of use

A bone cutting system comprising:

• a substantially rigid bone plate comprising
• an elongated body having a proximal end and a distal end and defining a longitudinal body axis;
• the bone plate comprising a bone contacting side, and opposing side, a left sidewall and a right sidewall, all of which extend between the proximal end of the bone plate and the distal end of the bone plate and all of which are substantially aligned with the longitudinal body axis;
• a proximal elongated slot extending through the bone plate between the opposing side and the bone contacting side located adjacent to the proximal end of the bone plate, the proximal elongated slot adapted to receive a bone screw;
• a distal elongated slot extending through the bone plate between the opposing side and the bone contacting side and adjacent to the proximal elongated slot but located distally on the bone plate relative to the proximal elongated slot, the distal elongated slot adapted to receive a bone screw;
• one or more bone screw holes extending through the bone plate between the opposing side and the bone contacting side and located distally on the bone plate relative to the distal elongated slot, the one or more screw holes adapted to receive a bone screw;
• a recess on the opposing side of the bone plate;
• a left track recessed into the left sidewall, the left track extending longitudinally between a track limit point and the proximal end of the bone plate, the left track being bound by an upper bounding wall, and a lower bounding wall, the lower bounding wall extending for the entire length of the left track while the upper bounding wall extends partially from a distal end of the left track to a location distal to the proximal end of the left track;
• and
• a right track recessed into the right sidewall, the right track extending longitudinally between a track limit point and the proximal end of the bone plate, the right track being bound by an upper bounding wall, and a lower bounding wall, the lower bounding wall extending for the entire length of the right track while the upper bounding wall extends partially from a distal end of the right track to a location distal to the proximal end of the right track;
• wherein portions of the left track and the right track that are bound only by a lower bounding wall provide an overhead entry to the left track and right track accessible from the opposing side of the bone plate;
• a bone cutting guide adapted to cooperate slidingly with the bone plate, the bone cutting guide comprising
• a handling feature;
• left and right guide walls extending downwardly from the handling feature and terminating respectively in left and right horizontal guide blades, the left and right horizontal blades adapted to mate with the left and right tracks of the bone plate respectively;
• an arm extending downward from one of the handling feature, the right guide wall, and the left guide wall, and comprising a flange;
• a cutting slot disposed on the flange;
• wherein when the left and right horizontal blades are engaged with the left and right tracks of the bone plate respectively;
• the cutting guide slides in a proximal-distal direction relative to the bone plate.
