Content
Referring to FIG. 9E, in certain embodiments, the patient-specific bone engagement feature (e.g., a bone engagement surface 944) is coupled to an inferior side 916 of the body 900. Alternatively, or in addition, the body 900 can extend from a medial side M of a foot bone over a dorsal side D of the foot bone to a lateral side L of the foot bone. In this manner, the patient-specific bone engagement feature can contact at least three points on the foot bone. These three contact points can provide a stable and secure placement of the resection guide 820b. In certain embodiments, the patient-specific bone engagement feature (e.g., a bone engagement surface 944) is configured to engage at least a portion of a cuneiform and at least a portion of a metatarsal of a patient when the resection guide 820b is used. The patient-specific bone engagement feature, such as a bone engagement surface 944 and/or a landmark registration feature 960 (discussed below), can include a contour that is at least partially determined based on a bone model of a patient’s foot. The bone model may be defined based on medical imaging of the patient’s foot.
