Paragraph Number

242

The reference feature can serve as a guide to a surgeon for a number of steps in a surgical procedure. In one embodiment, the reference feature includes a first reference feature and second reference feature. The first reference feature may include the set of proximal guide pins 928 deployed in a bone such as a cuneiform and the second reference feature may include the set of distal guide pins 930 deployed in a bone such as a metatarsal. Having two or more reference features can be advantageous because if a condition of a patient prevents deployment of one reference feature or the other, the second reference feature can serve as a backup. Furthermore, where a surgical procedure involves more than one bone, one reference feature can be established in a first bone and a second reference feature can be established in a second bone. Further, different stages of a surgical procedure may use one reference feature and not the other. Thus, having two reference features can facilitate certain stages of the surgical procedure.
