Fixing mechanism for closed distal femur osteotomy

A fixing mechanism for a closed distal femur osteotomy, which is configured to be installed on a femur incised by the closed distal femur osteotomy, the fixing mechanism comprising:

• a body portion having body coupling holes and an oblong hole, the oblong hole extending a predetermined length along a longitudinal direction of the body portion;
• a head portion connected to the body portion and having ahead coupling holes;
• body coupling screws inserted into the body coupling holes;
• head coupling screws inserted into the head coupling holes;
• and
• a sliding screw inserted into the oblong hole, the sliding screw being adjusted along the direction of extension of the oblong hole,
• wherein the head portion comprises a head lower surface configured to directly contact a lower femur and a head upper surface opposite to the head lower surface, and the body portion comprises a body lower surface configured to directly contact an upper femur and a body upper surface opposite to the body lower surface,
• wherein the head lower surface has a predetermined inclination angle in an upward direction based on the body lower surface,
• wherein the head coupling screws inserted into the head portion are directed toward a particular single point,
• wherein the head portion is tilted in a left or right direction with respect to the longitudinal direction,
• wherein the head coupling holes are aligned in rows and columns, and
• wherein a first imaginary line, which connects the centers of the head coupling holes formed along a first column on the upper head surface, is inclined 3 to 5 degrees with respect to a horizontal direction, which is vertical to the longitudinal direction.
