Content
FIG. 11E illustrates that the first height 1120 and the second height 1122 are defined such that the trajectory 1124 of the cutter guide 1010 extends substantially perpendicular to the longitudinal axis 1154 of at least one of the bones that is to be resected/dissected using the pivoting resection guide 1002. In one example, the longitudinal axis 1154 may be a long axis of a first metatarsal 208. In certain embodiments, the first height 1120 and second height 1122 may be of the same or substantially the same magnitude. The size of the first height 1120 and/or second height 1122 can vary depending on the contour of a bone surface that contacts the first bone attachment feature 1006 and second bone attachment feature 1008, the first angle 1150, the second angle 1152, an angle of the opening 1116, an angle of the opening 1146, whether the pivoting resection guide 1002 will span a joint and involve two bones, and the like. Advantageously, each of these aspects can be accounted for and accommodated when models of the bones of the patient and/or models of instruments such as the osteotomy system 1000 are reviewed and defined during preoperative planning stages in accordance with the present disclosure.
