1. A surgical apparatus comprising:
a tibial plateau leveling osteotomy (TPLO) plate including a body that includes a proximal region, a distal region, a first surface, and a bone contacting surface opposite the first surface,
wherein the proximal region is angled relative to the distal region such that the proximal region is offset from either a left-hand side edge or a right-hand side edge of the distal region,
wherein, for a right-hand side offset, both a left-hand side edge and a right-hand side edge of the proximal region are shifted to the right of the left-hand side edge of the distal region, or for a left-hand side offset, both the left-hand side edge and the right-hand side edge of the proximal region are shifted to the left of the right-hand side edge of the distal region; and
a first plurality of apertures passing through the body and each being configured to accommodate a fixation device;
wherein a longitudinal axis of the body bisects a majority of a length of the distal region and intersects through a first portion of the proximal region,
wherein the longitudinal axis intersects a first aperture of a first portion of the first plurality of apertures that are disposed in the proximal region,
wherein a second axis intersects each of a second aperture and a third aperture of the first portion of the first plurality of apertures,
wherein the second axis extends at an acute angle relative to the longitudinal axis,
wherein the second aperture is formed adjacent to a first curved peak of the proximal region and the third aperture is formed adjacent to a second curved peak of the proximal region,
wherein the first curved peak establishes a proximal-most tip of the proximal region.
