Paragraph Number

179

In this example, a surgeon has decided to do an arthrodesis procedure on the 1st TMT joint (between the medial cuneiform 202 and the first metatarsal 208). In virtual pane 610, a surgeon or other user may identify an axis 612 between a model of the medial cuneiform 202 and a model of the first metatarsal 208 which the user wants to use as a reference for checking the outcome of a surgical procedure near the final steps of the procedure. It should be noted that rather than aligning the axis 612 with a long axis of the first metatarsal 208, the axis 612 in virtual pane 610 extends more medial. In one embodiment, this difference may be because the surgeon intends to reorient the first metatarsal 208 and rotate the first metatarsal 208 such that sesamoids 258 are directed more plantar once the surgical procedure is completed. Virtual pane 630 illustrates that once the procedure is completed the axis 612 will align with the long axis of the model of the first metatarsal 208 and the model of the first metatarsal 208 will be substantially parallel to the model of the second metatarsal 210.
