1. An osteotomy guide configured to guide cutting of a bone, the osteotomy guide comprising:
an anterior end and a posterior end that are spaced from one another along a transverse direction;
an inner surface configured to face bone, and an outer surface opposite the inner surface along an outward direction, wherein each of the inner surface and the outer surface extends between the anterior end and the posterior end, and the inner surface defines:
i) a first arm that includes a first bone contacting region; and
ii) a second arm that is offset from the first arm with respect to the transverse direction and includes a second bone contacting region that is spaced from the first bone contacting region so as to define a gap therebetween that 1) extends from the first bone contacting region to the second bone contacting region, and 2) extends from the inner surface towards the outer surface along the outward direction, wherein the first and second arms are separated from one another by the gap;
at least one transverse guide surface that extends between the outer surface and the inner surface, and is elongate along a transverse axis that extends along the transverse direction so as to at least partially define a transverse cutting path into the bone, wherein the at least one transverse guide surface is offset from the gap along a distal direction;
at least one ascending guide surface that extends between the outer surface and the inner surface, and is oriented along an ascending axis that extends along an ascending direction so as to at least partially define an ascending cutting path into the bone; and
first and second push tabs, wherein the second push tab is offset from the first push tab in each of the distal direction, the transverse direction, and the outward direction, and the second push tab is offset from the first push tab toward the ascending guide surface, such that a center of the second push tab is disposed between a center of the first push tab and the ascending axis with respect to the transverse direction.
