12. A method for a Tibial Plateau Leveling Osteotomy (TPLO), comprising:
positioning a bone plate in a desired initial position with a first surface of the bone plate facing away from a tibia and a second surface thereof facing the tibia so that a proximal portion of the bone plate extends over a proximal tibial segment and a distal portion of the bone plate extends over a distal tibial segment that has been cut away from the proximal tibial segment and rotated and seated within a recess formed in the distal tibial segment when the proximal tibia segment was cut away;
inserting a first distal bone fixation element into the distal tibial segment of the tibia along a central axis of an offset portion of a first distal hole, which includes an elongated portion extending along a longitudinal axis of the distal portion of the bone plate and the offset portion extending distally from the elongated portion along an offset axis extending at an angle relative to the longitudinal axis; and
inserting a second distal bone fixation element into the distal tibial segment via a second distal hole extending through the distal portion of the bone plate distally of the first distal hole so that a head portion of the second distal bone fixation element slides along a sloped compression surface extending along a distal portion of the second distal hole to move the bone plate distally relative to the second distal bone fixation element and provide a first distal compression between the cut and rotated proximal tibial segment, the first distal bone fixation element translating proximally along the offset axis during the first distal compression so that the bone plate rotates about the second distal bone fixation element and the proximal portion of the bone plate is moved in a cranial direction to provide a cranial compression of the proximal tibial segment against the distal tibial segment.
