1. A surgical method, comprising:
collecting a set of patient data;
identifying at least one significant point from the set of patient data;
creating a surgical guide based on the at least one significant point and the patient data;
making a longitudinal incision on a lateral portion of a foot of a patient;
identifying and preserving one or more soft tissue structures;
coupling the surgical guide to a calcaneum of a patient;
performing at least one cut into the calcaneum using the surgical guide, wherein the at least one cut forms a recess in the calcaneum with the recess defined by a first calcaneal portion positioned substantially anteriorly from the recess and a second calcaneal portion positioned substantially posteriorly from the recess;
shifting at least one of the first calcaneal portion and the second calcaneal portion in at least one plane by placing an implant at least partially within the recess; and
securing the implant within the recess,
wherein the at least one significant point comprises at least one of an anterior facet, a middle facet, and a posterior facet of the calcaneum,
wherein the at least one cut extends at least partially between the anterior facet and the posterior facet in a medial-lateral direction,
wherein the first calcaneal portion comprises the anterior facet of the calcaneum, and the second calcaneal portion comprises the posterior facet of the calcaneum,
wherein the implant comprises a substantially wedge-shaped geometry.
