Fixing instrument for open-type distal tibial osteotomy

A fixing instrument for an open-type distal tibial osteotomy which is configured to be installed on an upper tibia and a lower tibia incised by the open-type distal tibial osteotomy, the fixing instrument comprising:

• a body portion comprising coupling body holes and an oblong hole, wherein the body portion has a top body end, a bottom body end opposite to the top body end along a longitudinal direction, an upper body surface, and a lower body surface opposite to the upper body surface along a vertical direction to the longitudinal direction;
• and wherein the lower body surface is configured to directly contact the upper tibia;
• a head portion comprising coupling head holes, wherein the head portion has an upper head surface and a lower head surface opposite to the upper head surface;
• and wherein the head portion directly contacts the top body end and the lower head surface is configured to directly contact the lower tibia;
• coupling body screws inserted into the coupling body holes;
• coupling head screws inserted into the coupling head screws;
• and
• a block detachably installed in the oblong hole by using a sliding screw,
• wherein the head portion is formed to have a predetermined angle based on the lower body surface,
• wherein the head portion is formed to asymmetrically tilt in a left or right direction with respect to the longitudinal direction, and
• wherein the bottom body end has two-stage body inclination sections having different inclination angles from each other along the longitudinal direction.
