Implant device for a tibial plateau leveling osteotomy

An implant device for a tibial plateau leveling osteotomy, comprising:

• an epiphyseal tibial plate section comprising at least two screw holes and a bone-contacting surface, each screw hole of the epiphyseal tibial plate section configured to accept a bone screw to secure the plate section to an epiphyseal tibial bone fragment;
• a metaphyseal tibial plate section comprising at least two screw holes and a bone-contacting surface, each screw hole of the metaphyseal tibial plate section configured to accept a bone screw to secure the plate section to a metaphyseal tibial bone fragment;
• and
• a ligament configured to join the tibial plate sections and to span a curvilinear tibial cut, wherein the curvilinear cut comprises a curvilinear cut radius and separates the epiphyseal and metaphyseal tibial fragments,
• wherein each of the epiphyseal and metaphyseal tibial plate sections and the ligament comprises an implant grade alloy,
• wherein the epiphyseal tibial plate section comprises an epiphyseal tibial plate section length and width, the metaphyseal tibial plate section comprises a metaphyseal tibial plate section length and width, and each tibial plate section length is at least two times longer than the respective tibial plate section width,
• wherein the width of each of the plate sections is substantially uniform along the length of each of the respective tibial plate sections,
• wherein the epiphyseal tibial plate section length is shorter than the metaphyseal tibial plate section length, and
• further wherein each of the cut-adjacent curvilinear surfaces generally matches a shape of the curvilinear cut and is curved in the same direction as the other cut-adjacent curvilinear surface for alignment along the curvilinear cut.
