Content
In the illustrated embodiments, resection guides 820b, 820c include a two resection features 822 (e.g., resection feature 822a and resection feature 822b). Resection feature 822a may be similar to, or may be, a proximal slot 828 and may be near the proximal end 824. Resection feature 822b may be similar to, or may be, a distal slot 832 and may be near the distal end 826. Thus, as with a proximal slot 828 and/or a distal slot 832, the resection feature 822a and resection feature 822b can guide a cutting tool to form a first osteotomy in a first bone and a second osteotomy in a second bone, respectively. The first osteotomy in the first bone along the first trajectory and the second osteotomy in the second bone along the second trajectory may have a first trajectory and a second trajectory determined based on an angle of at least of portion of the respective resection feature 822a, 822b through the body. In certain embodiments, one or more of the first trajectory and the second trajectory may be at least partially determined based on a bone model of a patient’s foot. The bone model may be defined at least in part based on medical imaging of the patient’s foot. The first trajectory and the second trajectory determined at least in part based on the bone model may determine final trajectory or a proposed trajectory that a surgeon can then alter or revise as needed to accomplish a desired outcome. The bone model may be a model of both the first bone and the second bone or of one of the first bone and the second bone. In one embodiment, the first bone is a cuneiform, and the second bone is a metatarsal. In certain embodiments, the cuneiform and the metatarsal may be of a patient and may be a cuneiform and a metatarsal that are both part of a particular joint such as a TMT joint.
