Offset hole for tplo compression

A Tibial Plateau Leveling Osteotomy (TPLO) plate for providing a cranial and a distal compression of an osteotomy cut, comprising:

• a body extending longitudinally from a proximal end to a distal end and defined via a first surface which, in an operative configuration, faces away from a bone and a second surface which, in the operative configuration, faces toward the bone, the body including a proximal portion configured to be positioned over a cut and repositioned proximal segment of a tibia during a TPLO procedure and a distal portion extending along a longitudinal axis and configured to be positioned over a distal segment of the tibia during the TPLO procedure;
• a first distal hole extending through the distal portion of the body, proximate the distal end thereof, from the first surface to the second surface, the first distal hole including an elongated portion and an offset portion open to and in communication with one another, the elongated portion extending along the longitudinal axis and an offset portion extending distally from the elongated portion along an offset axis, which extends at an angle relative to the longitudinal axis;
• and
• a second distal hole extending through the distal portion of the body proximally of the first distal hole from the first surface to the second surface, the second distal hole extending along the longitudinal axis in alignment with the elongated portion of the first distal hole and including a sloped compression surface along a distal portion thereof,
• wherein the first distal hole is configured such that when a first distal compression to the osteotomy cut is applied via insertion of a bone fixation element into a distal portion of the second distal hole, the bone fixation element translates along the offset axis from a central axis to a point of intersection to provide a cranial compression and a first distal compression to the osteotomy cut.

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 a 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.
